[ID 20010825.006] -DCRIPPLED_CC is broken
Message ID:
20010825174459.O41464@plum.flirble.org
This is a bug report for perl from nick@talking.bollo.cx,
generated with the help of perlbug 1.33 running under perl v5.7.2.
-----------------------------------------------------------------
[Please enter your report here]
Are we still supporting compilation with -DCRIPPLED_CC?
If no, why haven't we taken it out?
If yes, how can it be fixed?
The problems seem to be due to definitions in sv.c which only occur inside
an #ifndef CRIPPLED_CC block:
#ifndef CRIPPLED_CC
/* redefine some things to more efficient inlined versions */
/* Let us hope that bitmaps for UV and IV are the same */
#undef SvIV
#define SvIV(sv) (SvIOK(sv) ? SvIVX(sv) : sv_2iv(sv))
#undef SvUV
#define SvUV(sv) (SvIOK(sv) ? SvUVX(sv) : sv_2uv(sv))
#undef SvNV
#define SvNV(sv) (SvNOK(sv) ? SvNVX(sv) : sv_2nv(sv))
/* flag values for sv_*_flags functions */
#define SV_IMMEDIATE_UNREF 1
#define SV_GMAGIC 2
#define sv_setsv_macro(dsv, ssv) sv_setsv_flags(dsv, ssv, SV_GMAGIC)
.
.
.
1: Those SV_IMMEDIATE_UNREF and SV_GMAGIC definitions appear to be in the wrong
place, as they are needed in sv.c independent of the setting of CRIPPLED_CC
sv.o is failing to build.
2: The section inside the #ifndef CRIPPLED_CC block seem to provide the only
definitions of a lot of "functions" such as sv_setsv. With CRIPPLED_CC
defined sv.h doesn't map things like sv_setsv into a call to
Perl_sv_setsv_flags, resulting in warnings such as:
CCCMD = cc -DPERL_CORE -c -DDEBUGGING -DCRIPPLED_CC -fno-strict-aliasing -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -g -Wall
regcomp.c: In function `S_scan_commit':
regcomp.c:499: warning: implicit declaration of function `sv_setsv'
regcomp.c: In function `S_study_chunk':
regcomp.c:887: warning: implicit declaration of function `sv_catpvn'
regcomp.c:1232: warning: implicit declaration of function `sv_catsv'
so even with sv.o building the link is going to fail.
It's not totally clear to me what all the mappings in sv.h are about, so I
didn't really want to attempt a patch and get it subtly wrong.
