B-C - Changes

-- change-log --

        Started on CPAN with B-C-1.04_12
        The Perl compiler was in CORE from alpha4 until Perl 5.9.4
        and worked quite fine with Perl 5.6 and 5.8

          init order (44).
        add CVf_CVGV_RC flag (refcount) on CV with no backref magic, e.g. END (48)
        added option -i includeall which adds no BEGIN require ops, but adds
          all included symbols.
        better BEGIN block @INC manipulation detection (33)
        print newsvx flags if -S or Comment

          just set them once.
        added try_isa before try_autoload. use mro::get_linear_isa instead of @ISA
        mark_package force: detect and fix already discarded packages which
          are brought back in directly or by someone else's @ISA. (e.g. Sub::Name
          needs DynaLoader::dl_load_flags)
        improved method_named package search, still not exact though (LWP)
        add manually compiled packages to %INC to avoid a runtime require
        special case Config detection, AUTOLOAD = launcher, included by Dynaloader

        [perl #86186] force binary IO for __DATA__ handles, which changed
          in core with 5.14
        * bytecode.pl:support  m for MULTIPLICITY (yet unused)
        * Makefile.PL:move  cc_runtime.h installation to make install step
          (sudo). Tested ok on darwin gcc, does use -I. internally.
        * cc_runtime.h: renamed from cc_runtime514.h
        * cc_harness: fixed darwin coredir
        * perlcc (2.11): fixed darwin coredir.
        omit darwin linking to dynamic .bundle - generate .a via libtool

dbmopen, cc_runtime.h, perlcc, --staticxs

C.pm (1.30): support dbmopen, fixes issue 24. fixed xpvmgsect (was xpvsect) !-fcog < 5.10 (YAML, test 41,42,43). fixed m//i since 5.13.10: swash_init("utf8::Cased"). fixed method_common package_pv detection in most cases. still two cases open, without tests. PADOP GV NULL 0x20000, GV RV 0x40802. fixed method_named with >= 1 arg, checking for const PV package_pv (test 35) support GvCV_set and GvGP_set introduced with 5.13.10. [RT#65630] implement -staticxs for perlcc --staticxs either link to found static libs or link to shared lib with fixed LD_LIBRARY_PATH/PATH (nyi in C, just perlcc). optimize -fav-init use_av_undef_speedup &PL_sv_undef initialization (again). reserved -mPackagename (NYI) added verbose(),module() for CC. implement outline of -m module, name detection missing. added -fno-fold recommended since 5.13.9 to omit the huge utf8 tables. added -fno-warnings, recommended since 5.13.5. added special workaround for Scalar::Util bootstrapping which did not detect List::Util, since it is not in its ISA, only required. need a better scan. fixes test 44. init XS within Od. prevent autoloaded STDERR printing on non-debugging perls (e.g. "Storablelogcarp").
CC.pm (1.09): support dbmopen, issue 24 failing due to XSLoader (test 45) no pp_name shortnames in embed.h since 5.13.9, use Perl_pp_name(aTHX). implemented dorassign, fixes issue 45. fixed XSLoader detection, moved use_xsloader to save_unused_subs() skip duplicate cc(pp_sub_*) functions (freebsd 45) added missing END block code (test 28). added B::C::verbose on -v fixed B::C::verbose crash by adding B::FAKEOP::fake_ppaddr. fixed compile_stats renamed -n module_name to init_name. check and set -f options from C also. implement outline of -m module, name detection missing. added option -fno-name-magic. added experimental option -ftype-attr. added TYPES pod section. added pod for some funcs: load_pad, cc_queue, label. option -strict only used with DEBUGGING perls. be less chatty with compiling bblocks. light layout cleanup of generated code sections. added Vishal Bhatia <vishal at deja.com> to AUTHORS.
Bytecode.pm (1.10): support dbmopen, fixes issue 24. re-added -m, compile as module to .pmc store AV elems for non-tied AV->MAGICAL >5.6 (i.e. @ISA, ...) (new test 47). -DA: limcheck PV. verbosity: added nice1 (condense elements). name SV indices also.
Byteloader: support GvCV_set introduced with 5.13.10 [RT#65630]
perlcc (2.10): fixed -B -r, -B output and run bytecode. implement --staticxs to workaround DynaLoader problems. use it in t/modules.t add sopath to PATH on -r. Without -r the sofile should be symlinked so that the process can find it. implement --shared and --static, --shared fails on strawberry due to core problems. implemented getopts bundling: -ScO -e'bla' -v4 -oa is now possible. disabled some old single-minus switches: -testsuite, -time, -log, ... requires now double-minus --testsuite, --time, --log, ... kept legacy handling only for -Wb=.. and -stash. fixed -B -e'oneliner'. fixed -B @ARGV, no duplication of @ARGV, c_argv.t 3. re-added -m|--sharedlib for Bytecode and C (NYI). print C and CC filtered compiler output. -v5 adds -v to the compiler options. -v6 adds -Dfull to the compiler options. support -Wb= for -B. fixed -Br for 5.6: add -MByteLoader.

Disassembler (1.08): 5.6: fix ldop comments. add op_type names, add @svnames, add indices, add ldspecsvx type.
Assembler (0.10): print more flags (as hex) and indices. better limcheck diagnostics (op,sv,pv).
cc_runtime514.h: removed from CORE with 5.13.9. [RT#65628] If so, cp it back. You might need sudo cp. (unchecked) Renamed not to pollute tests with older perls. Expanded PERL_MAGIC_taint 't' for 5.6.
C.xs: added experimental method_cv for the hash-only case, untested.
t/modules.t: try --staticxs first, try crosscheck without perlcc.

        fail sometimes. Tested ok with strawberry 5.10.1

        * C.pm: fixed evaltry (test 12) mostly, NVX was shared with 2 xpad_cop_seq ints
          which accidently just worked before 1.17 with %s, but not after changing
          to the %g representation.
        Ignore unused random (overlong) xpviv IV, causing
          "warning: this decimal constant is unsigned only in ISO C90"

        * bytecode.pl:added  cop_seq_low (155), cop_seq_high (156) instead of xnv.
          No conversion code for loading older bytecode needed, but fragile (double => 2 int)
         t/modules.t: refactored by Todd Rinaldo (toddr). 4tests per module:
          -s a, exitcode 0, ok, no warnings on stderr
        * t/TESTS: added 38, failing on CC (Nick Koston).

1.17 2010-02-03 rurban

        Fixed now most module failures, non-threaded at least: bootstrap was in
        the way. strawberry perl fixes. Fixed test 29, broke evaltry test 12

        * C.pm: Added option -Dfull for all full debugging info, set all options.
        Skip saving XS bootstrap. Fixes most XS module failures. i.e.

        Fixed xrv_list "initializer element is not constant" (Class::MOP < 5.10)
        * CC.pm (1.06): Added missing unexported definitions for MSWin32,
          >=5.10: newGP, vivify_ref, prepare_SV_for_RV (tests 18, 29).

use Moose and benchmark still fails. IO even a regression.

C.pm: Fixed braces warning for empty xpvcv startfield (Nullany), register int for warn_sv loop Fixed hv init for magic hashes, pre-allocate array and xpvhv_aux. (test 34) Fixed method_named (CPAN #53889, test 35) for B::C, better fix than for B::CC. Added -DH for HV debuggging. Fixed HV self-references causing endless loops, i.e. with use Moose, test 36.
CC.pm (1.05): added experimental -finline-ops. Always on. Can be removed if it works okay for the new inlined versions. Inlined pp_enter, pp_reset, pp_regcreset, pp_stringify. Fixed pp_padsv DEREF for 5.10. Documented test coverage for each op. Fixed wrong $PERL511 definition. Added Opcodes support (no_stack), on CPAN as 0.01. added pp_pushmark pp_break pp_continue to no_stack handling. Fixed method_named (CPAN #53889, test 35) assuming there is only const before method_named. No counter examples found so far. Changed new OBJ => OBJ->new More curcop->write_back protection.
Stackobj.pm (1.00_02): RV fix for 5.11.
t/testc.sh, t/test.pl: added CC specific tests to increase CC op coverage after 100. Switched test 32->101 (arith) with 33->32 (evaltry catch die) as it fails with 5.11.3. Added new qr test 33 (Nick Koston), test 34 for magic hashes, test 35 for broken methodcall syntax (method_named), test 36 for HV self-references.
TESTS: added test 32 (evaltry catch die): Fails on 5.11.3 C/CC only, <5.11.3 it works okay. Also tests 33, 34, 35, 36.
ByteLoader/Makefile.PL: removed cygwin gcc specific stack-protector removal. It was a bug of mine. Added more AUTHOR gcc -ansi warnings, just -pedantic not.
Makefile.PL: Added more AUTHOR gcc warnings, also -pedantic. Added optional Opcodes PREREQ_PM

1.15 2010-01-03 rurban

t/test.pl: Fixed MSWin32 tests again. Lost the 1.13 patches with 1.14.

1.14 2010-01-02 rurban

CC.pm (1.04): Fixed entereval/leaveeval for 5.10. Fixes eval "", test 12. The end of the string CALLRUNOPS needed to be nullified, as in 5.8. 5.11 CORE also needs a patch for this. Optimized away SP save/restore for %no_stack ops. Need to read this from opcode.pl eventually. PERL_ASYNC_CHECK (pending signals) added after every basic blocks with -O1 and every loop.
C.pm: More 5.10 union braces.
Stackobj.pm (1.00_01): Added iv and nv to peek. Added documentation.
Bblock.pm (1.03_01): Print the argument (sub) to inspect. Added missing documentation.
t/testcore.t: improved. added -fail and a list of failing tests. C now always with -O3.
t/c_allow_opts.t: Added for -DALLOW_PERL_OPTIONS.

1.13 2009-12-31 rurban

        Tested with MSVC (MSVC compiles test29 and bigger examples awfully slow!
        7:30min, 30MB mem, 98% CPU, 2GHz)

         C.pm: MSVC fix for "(OP)Nullany" i.e "(OP*){0}" => "{0}". Fixes
          test 27 on MSVC. CC test 12 broken on MSVC AS 5.8
        * bytecode.pl:Restore  C strictness, printf before declaration.
        Undefine debop for MSVC also. Fixed [cpan #53228].
        * t/test.pl: Cleanup intermediate MSVC .obj. Skip too slow tests 29
          on MSVC, only c.t
        Remove >nul for test results on Win32.
        More run_cc_perl fixes for Win32.
        Be more quiet on MSWin32 also (no 2>/dev/null)
        Skip stderr redirection to stdout on cmd.exe tests, t/o.t 5,9.
        * t/bytecode.pl: ditto.
        * t/TESTS: Fixed 28 for MSWin32 MSVC

1.12 2009-12-31 rurban

        __DATA__ handles work now. Also more Bytecode fixes.
        * t/testplc.sh: Added -S: skip all but -S and Concise
        * Bytecode.pm (1.05): Adapt RV 5.11 change from SV to IV, detect ROK at
          B::IV::bsave analog to C.pm. Fixes test 16.
        Set prototype sv_flags at first, so it cannot assert. Fixes tests 27 and 29.
        More work on 5.6 compat.
        * bytecode.pl:Fixed  5.6 %alias_to sizes.
        * bytecode.h: Fix BSET_cop_label for 5.11. Fixes test 21.
        * t/bytecode.t: Added DEBUGGING to the mix. 5.11 is now completely the
          same as 5.10. Remaining failures are now 9,10,12 for DEBUGGING (or
          non-threaded?).
        * C.pm: Added xpvuv (coverage in 5.6.2 test 21).
        Added PMOP->pmstash/pmstashpv (no coverage yet).
        Checked against -Wall -Wextra:
          Added missing pmop->stash for 5.8.
          Added missing cop->cop_io for 5.8.
          Added braces to union inits (MSVC Todo).
          Remove unused dTARG and dSP.
        Fixed CC test 29 on 5.6.2, not checked why.
        Fixed __DATA__ test 15 on 5.10 and 5.11.
        * TESTS: Updated with 5.10.1 CORE results

1.11 2009-12-29 rurban

        Fixed 5.11 RVs, added C optimizations to CC
        * C.pm: Adapt RV 5.11 change from SV to IV, detect ROK at B::IV::save.
          Fixes test 16.
        Added -DW for walk, together with -Dp only.
        Forced fullname optimization scalars for B::CC.
        Export save_sig and fixup_ppaddr for CC.
        * CC.pm (1.03): Fixed Perl_gv_SVadd cast warning.
        Added most B::C optimizations. This fixes all threaded tests 15 >= 5.10.
        Call save_sig, fixup_ppaddr not yet.
        * t/test.pl: simplified (and fixed) keep logic
        * t/c_argv.t: cleanup

1.10 2009-12-29 rurban

        Fixed @ARGV
        * C.pm: fixed couple of minor bugs detected with new t/testcore.t:
          t/CORE/comp/retainedlines.t => Use of uninitialized value $len, save_hek
          Use of uninitialized value $i in printf at C.pm line 49
          Undefined value assigned to typeglob at C.pm line 2901
        Do not overwrite run-time @ARGV on >= 5.10 (GP and AV). Fixes test c_argv.t
        * t/testcore.t: added
        * t/c_argv.t: added. test @ARGV and perlcc
        * perlcc (2.06): grab_stash only via new -stash, not automatically;
          B::C is better.
        ldopts -std only when modules are given.
        fix for empty options.
        add -sharedxs, -sharedlib; -shared is now for shared linkage,
          -sharedlib to create a shared lib (was -shared before but never worked),
          -sharedxs to also link shared xsubs, no run-time DynaLoader/XSLoader needed.

1.09 2009-12-27 rurban

C.pm: Cut down the number of AUTOLOAD'ed optrees, search only on empty gv->cv (31). Added very unsafe -O4/-fcop to eliminate most cops and file + line numbers. Added faster -fav-init to -O2, less unneeded av_extend(). Get rid of fbm_compile (11). Only 5.8.9 is broken.
CC.pm (1.02): partially fix eval "" for >=5.8.9, wrong CORE cc_runtime.h definition. (test 29 - eval "")
t/test.pl, t/c*.t: Simplify C/CC testsuite.
t/testc.sh: fixed -E Added -o for orig, no -Mblib
t/c_o3.t, t/c_o4.t: added

1.08 2009-12-23 rurban

Adapt coding guidelines, add C and cperl coda. Reformat sources.

C.pm: Detect AUTOLOAD and CLONE (test 27 and 31). 5.10 is now the best release for unoptimized B::C. 5.8 is faster optimized, but misses some autoloaded xsubs. Simplify PVMG exclusion; all non-magical, not just PAD_OUR, as in Bytecode.
Bytecode.pm (1.04): Add missing BM logic to GV >= 5.10. Fixes test 11. Fixed op_pmflags logic for 5.10 threaded only, no += 2. Fixes test 2. Protect empty match from setting op_reflags. Fixes test 20. Add perlversion to the -S generated header. Document more options -TI, -TF, -u<package>
perlcc: improve help. use Pod::Usage as module, not via cmdline. fix previous installation quirks.
assemble: improve pod. make it installable.
disassemble: make it installable.
cc_harness: ditto.
Makefile.PL: added script/* as EXE_FILES to install them.
t/TESTS, t/testc.sh, t/testplc.sh: test 31 non-xs AUTOLOAD added
ByteLoader/Makefile: tuning, bytecode.h triggers now byterun.c
bytecode.h: Specialize pregcomp on 5.10; add PL_regex_pad[0] for pregcomp if missing. fixes tests 3,4,5,7,31 on 5.10.

1.07 2009-12-19 rurban

C.pm: fix fbm_compile (INDEX) for >= 5.10. gv_list is already a pointer. rewrite PVGV (ie PVBM) init for >= 5.10. (test 11) Added CV->save_magic (untested) Fixed two wrong my decelarations detected by the new Od debugger.
README: Clarify DIFFERENCES section for CC only. Esp. the Context of ".." section. New test 30
t/TESTS, t/testc.sh, t/testplc.sh: test 30 added for Context of ".."
t/testc.sh: fix -k logic, keep .pl for -O tests

1.06 2009-12-18 rurban

        Going public on the Perl birthday
        The first public compiler re-release since it was removed from CORE.

        * C.pm: Had to disable -O1 -fcog (pv_copy_on_grow) on 5.10 and higher
          until I find out how to fool S_unshare_hek_or_pvn. This fixes all C
          -O1 and -O2 tests. Warn about this.
        Fix wrong RV init on 5.10 for test 29 also, as with 5.11.
        Simplify __DATA__ handling. Warn when -O3 or -fsava-data is missing.
          Enable working -fsava-data on 5.8 and 5.10 threaded. Fixes couple of tests 15.
        Fix 5.8/5.10 PVMG pv = &PL_sv_undef for empty comppadnames
        * t/testc.sh: -k keep added. Delete temporaries on PASS as new default.
        -E added. Dump preprocessed source file with cc -E as _E.c (was default before)
        * Version bump to official:
          B::C 1.06 (1.05 is in 5.8.9)
          B::CC 1.01
          B::Bytecode 1.03
          B::Asmdata 1.03

CC.pm: fix ARGS >=5.10 (in require, test 28). Enable quiet. No -q for quiet, just -v (verbose) or any -D switch turns on verbose.
t/testc.sh: Added test 27 (import), test 28 (require), test 29 (use) [Nick Koston]

1.04_32 2009-12-14 rurban

Only two 5.10 B::C bugs remaining!

C.pm: added missing FBM logic to GV >= 5.10 (test 11). Forbid MAGIC on non-magival SVs >= 5.10 (tests 14 + 23). Special PVMG PL_sv_undef string. (namesv problem on 10,14,23)

t/testc.sh: fix -D option

1.04_30 2009-12-13 rurban

        Better 5.6 support, but Bytecode compiler still disabled.
        Not even the Byteloader works for 5.6 assembled code. The Disassembler
        does not stop at ret. Fixed several C tests.

        * bytecode.pl:renumbering  policy: <= 5.6 squeeze, >= 5.8 fixed
        to force exact bytecode numbering as with 5.8.
        Allow float versions, such as 10.001 for subreleases.

        Add perlversion to header.
        Add byteorder check logic.

        Added logic to include all possible unsupported ops, all holes.
        bytecode table checked for 5.6.1, 5.6.2, 5.8.0, 5.8.1-5.11
        Note, that I found official and contradicting 5.6.1 releases.
        ActiveState 5.6.1.626 had no op_children, the unix release tarball
        with 5.6.1 (called Trial 1) still has it.

        * ByteLoader.pm (1.06_06): better bytecode numbering.
        * Asmdata.pm (1.02_02): strict numbering along 5.8.
        Unsupported ops are now also included, with PUT method 0.
        * Assembler.pm (0.07_07): Add perlversion to header
        * Disassembler.pm (1.05_04): Add perlversion to header.
        Print header only for existing.
         BcVersions/Asm.pm, BcVersions.pod:added  for most versions with the
        CORE compiler.
        * disassemble: Make it work with the older Disassembler.
        Make it work with older bytecode >= 5.8 via Asmdata unsupported ops.
        * i386.xs, jitcompiler.pl:removed  (seperate module)
        * bytecode.h, C.xs: Fixed for 5.6, tested with 5.6.1 with MSVC.
        * bytecode.h, byterun.c: add static int force = 0. Override it to 1 to
        try out executing older bytecodes.

        * C.pm: fix test 16 on 5.10 again, non-threaded only (GVAV magic).
          first fix in 1.04_24, broken in 1.04_28. On 5.11 I have a broken
          RV handling here.
        Remove version and Regexp::DESTROY from the automatic methods
        (experimental).
        First attempts with pv and hek consting failed.
        * t/testc.sh, t/testplc.sh: support proper cmdline arguments, add -h for
        help
        Fixed test 5 by fixing the wrong test.
        * perloptree.pod:renamed  from perloptreeguts.pod. Added links.

1.04_29 2009-12-07 rurban

        Disable the Bytecode compiler for 5.6. Fixed besides the __DATA__ handle
          (test 15) all remaining 5.8 C bugs.
        * C.pm: assign the PVX of GV also for empty stashes (main::) to avoid
          destruction failures at Perl_pad_undef() SvPVX_const(namesv) == '&'.
        Fixes tests 14 and 23
        * byterun.c: No assert on empty bs_sv, it is &PL_sv_undef.
        Map missing -Dv on 5.6 to -Df i.e. -D256
        Added better debugging output: setter values.
        * STATUS: re-run CORE tests, list cmdlines, update status
        * Disassembler.pm:added  gen_header_hash() for gen_header output.
          add to documentation.
        * Bytecode.pm:-S  uses gen_header_hash for gen_header output.

1.04_28 2009-12-06 rurban

C.pm: fix -fcog (Copy on Grow with -O1 and -O2) for >= 5.10 by a new SVPV. Statically initialize PVs with a union layout trick. Use char* as first union member. Revert xpvcv+svsect changes to pre-initialize those structs against gvcv recursion.
t/b.t, t/o.t, t/stash.t: fix tests for 5.6.2
bytecode.c: byteorder swab only if same length. 1234 => 4321, 12345678 => 87654321. Skip a 0x prefix for byteorder in the header. Perl 5.6 had this.
Assembler.pm (0.07_06): 5.6 byteorder fix: until 5.6 the $Config{byteorder} was falsely dependent on ivsize, we need longsize. Add 0x to byteorder in header again, as with 5.6.
t/testc.sh: do not run old leftovers. some 5.6 optimizations
t/c_o1.t, t/c_o2.t, t/cc_o2.t, t/cc_o2.t: added
t/test.pl: support -O1 and -O2

        Fixes for no ithreads.

        * Fixed verbose Bytecode for old B::Concise (5.8.8). t/testplc.sh
          failed before.
        * ByteLoader: Work on portability (different arch, version and sizes).
          Added bl_header.
          Changed macro BYTECODE_HEADER_CHECK to function bytecode_header_check().
          Fixes for no threads.
        * bytecode.h: pregcomp fix for 5.10 w/o threads
          (Thanks to david@cantrell.org.uk for his cpantest for netbsd).
          use xpv_cur and not xpv_len for the rx length (len - 1) to strip off
          the ending nul byte.
          5.10: new minlen check aborts
        * ByteLoader security: added strconst maxsize flag to bytecode.pl
          for buffer overflow checks.
        * Bytecode -DA for devel assertions of absolute or probably wrong opindex
          pointers (nyi)
        * disassemble, B::Assembler: commented output, similar to -MO=Bytecode,-S
          Added backwards option --bare for older assemblers.
        * assemble, disassemble: added pod
        * B::Disassembler:
          Provide default printers print_insn (commented) and print_insn_bare.
          Portability: Use the header settings from the .plc and not the current
          perl settings.
        * B::Assembler 0.07_03, B::Disassembler 1.05_02, ByteLoader 0.06_03:
          Added longsize to the bytecode header, just for xcv_depth.
        * B::Debug 1.05_03: Fixes for no threads.
         Makefile.PL:Fixed  script/perlcc.PL dependency
          make: ** No rule to make target `script/perlcc', needed by
          `blib/bin/perlcc'.
          (Thanks to david@cantrell.org.uk for his cpantest for solaris)
        * Added test TODO's, Added perloptreeguts.pod

bytecode.pl:Exterminate !
ext/B/B/Asmdata.pm: Exterminate!

Nicholas Clark <nwc10+p5p4@colon.colondot.net> 2007-05-07 14:53:05

Given that @optype and @specialsv_name are hard coded tables, it seems more logical for them to be in B.pm, rather than in the "boilerplate" for the machine generated B/Asmdata.pm

Marcus Holland-Moritz <mhx-perl@gmx.net> 2004-08-29 13:22:48

Vishal would appreciate comments about B::Stackobj changes from someone knowing that module well.

Nick Ing-Simmons <nik@tiuk.ti.com> 1998-12-05 11:44:28

@2452 B.xs had its own code to calculate hash() which differed from PERL_HASH in hv.h - so all saved HV's were mangled - including %INC which meant that run-time require was re-done. Removed some debug from C.pm

Nick Ing-Simmons <nik@tiuk.ti.com> 1998-12-04 22:58:49

@2451 Snapshot of re-worked B::C which compiles Tk apps at least as well as _54, but with pre-scan for classes and save the ISA scheme.

Nick Ing-Simmons <nik@tiuk.ti.com> 1998-11-28 23:46:57

@2378 More C.pm tweaks
Save globs even if we have saved cv itself before - may be imported.

      While we don't save "bootstrap" CV we need to provide a stub,
      so that if we require it later we don't fall through and attempt
      to DynaLoad module again.

      Attempt to save %INC so that "require" does not reload things
      we have compiled-in (does not work right yet - seems to be due
      to PL_incgv being created in perl_parse() current scheme setting
      GvHV() is "better" than saving the glob, but still does not
      work as I expect).

Nick Ing-Simmons <nik@tiuk.ti.com> 1998-11-27 22:10:27

@2332 Handle INIT list in C.pm

Provide init_av() from B.xs
Export it in B.pm
Use it in C.pm Also disable some pruning in savecv() which seems to undo my previous patch. Experimental feature - save pathnames of .so files in easily grep-able form for use in wrapper to feed to linker.

Malcolm Beattie <mbeattie@sable.ox.ac.uk> 1998-02-20 16:42:13

Merge perlext/Compiler/... into mainline. Some files move to ext/B/..., some to lib/B/..., O.pm and B.pm go in lib and some move to the base perl directory (e.g. headers). Will need some cleaning up before it builds properly, I would guess.
