12 years agounify PERL_HASH and PERL_HASH_INTERNAL
David Mitchell [Thu, 28 Apr 2011 15:33:35 +0000 (16:33 +0100)]
unify PERL_HASH and PERL_HASH_INTERNAL

Those two macros expand into two large, almost identical chunks of code.
The only difference between the two is the source of the hash seed.
So parameterize this into a new PERL_HASH_INTERNAL_() macro.

Also, there are a couple of places in hv.c that do the rough equivalent of

    if (HvREHASH(hv))
key = PERL_HASH_INTERNAL(...)
    else
key = PERL_HASH(...)

which incorporates two complete macro expansions into the code.
Reorganise them to be

    key = PERL_HASH_INTERNAL_(..., HvREHASH(hv))

[perl #90122] Make h2ph correctly search gcc include directories

System header conversion with "h2ph -a" is currently broken on Ubuntu
Natty and Oneiric (unless the gcc-multilib package is installed for
backward compatibility), resulting in things like

 # perl -e 'require "syscall.ph"'
 Can't locate asm/unistd.ph in @INC [...]

This happens because Ubuntu has switched to a 'multiarch' setup, see
<https://wiki.ubuntu.com/MultiarchSpec> for details.

The asm subdirectory isn't in $Config{usrinc} anymore: /usr/include/asm
is now /usr/include/x86_64-linux-gnu/asm. (The third component of the
new path varies with the actual architecture.)

gcc --print-search-dirs doesn't really tell anything about where gcc
looks for the include directories, it was just used to find the gcc
internal directory prefix.

Parse the output of "gcc -v -E" instead, and append $Config{usrinc}
for safety. Duplicates shouldn't matter.

The h2ph "-a" switch isn't currently tested automatically, and that
seems nontrivial to do portably. Manual testing was done with

 # mkdir ttt
 # ./perl -Ilib ./utils/h2ph -a -d $(pwd)/ttt syscall.h

The gcc invocation has been tested to work with gcc 4.6, 4.1, and 3.3.

namely the code starting at line 2132 of
900ac0519e4b408fd93443b14b734cc330c59698:hv.c:

the raw string by extending the buffer, and calculating the first U32 aligned
address after SvCUR(). A flag bit on the scalar was set to signal this hackery,
tested with SvCOMPILED()

The flag bit used happened to be the same as one of the two used by to signal
Boyer-Moore compiled scalars. The assumption was that no scalar can be used for
both. Unfortunately, this isn't quite true.

Given that the scalar is alway upgraded to PVMG to add PERL_MAGIC_fm magic,
to clear the cached compiled version, there's no extra memory cost in using
mg_ptr in the MAGIC struct to point directly to the block of U32 opcodes. The
test for "is there a compiled version" can switch to mg_find(..., PERL_MAGIC_fm)
returning a pointer, and the use of a flag bit abolished.

Retain SvCOMPILED() and SvCOMPILED_{on,off}() as compatibility for XS code on
CPAN - the first is always 0, the other two now no-ops.

12 years agoS_doparseform() should return void, not OP*, as it should use Perl_die not DIE

S_doparseform() should return void, not OP*, as it should use Perl_die not DIE

a1b950687051c32e added an error condition in S_doparseform() but used DIE(...)
to report it. DIE is defined as C<return Perl_die>, which acts as a hint to the
compiler about the control flow [as Perl_die() never returns], but also forces
the return type to be OP *. Whilst this is appropriate for pp functions, it's
not for S_doparseform() - a1b950687051c32e had to change the return type to OP*
and return NULL, just to appease DIE(). Hence use Perl_die() instead, remove
return statements, and remove the didn't-return-NULL (dead) code from
pp_formline.
