From 37f91d336d8d93b1416c121627ffe88e548b251d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 21 Feb 1995 06:02:58 +0000 Subject: Tue Feb 21 00:10:50 1995 Roland McGrath * csu/Makefile (crtstuff): New variable consolidates crti, crtn; add crti_s, crtn_s. (install-lib, extra-objs, generated-, omit-deps): Use that. (initfini): New canned sequence, broken out of crt[in].s rule. (crt[in].s rule): Use it. (crt[in]_s.s): New rule. * csu/initfini.c (GLOBAL): New macro; define it to empty if undefined. (_init, _fini): Use GLOBAL as storage class. Add self reference to avoid GCC optimizing out the functions. * Makefile (headers): Remove $(stddef.h). * Makeconfig (stddef.h): Variable removed; now require gcc version >= 2.2. * stddef.h: File removed. Mon Feb 20 19:42:31 1995 Roland McGrath * sysdeps/unix/bsd/ultrix4/mips/start.S: Remove `__environ' definition. * sysdeps/unix/bsd/osf1/alpha/start.S: Likewise. * stdlib/strtod.c: Allow the string to start with a decimal point without a leading zero. --- sysdeps/unix/bsd/Attic/osf1/alpha/start.S | 7 ------- sysdeps/unix/bsd/ultrix4/mips/start.S | 7 ------- sysdeps/unix/start.c | 12 ++++-------- 3 files changed, 4 insertions(+), 22 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/unix/bsd/Attic/osf1/alpha/start.S b/sysdeps/unix/bsd/Attic/osf1/alpha/start.S index 8b7109a..52eb036 100644 --- a/sysdeps/unix/bsd/Attic/osf1/alpha/start.S +++ b/sysdeps/unix/bsd/Attic/osf1/alpha/start.S @@ -18,13 +18,6 @@ Cambridge, MA 02139, USA. */ #include -#ifndef HAVE_WEAK_SYMBOLS -#define __environ environ -#else -weak_alias (__environ, environ) -#endif - -.comm __environ, 8 .comm errno, 4 !.sdata diff --git a/sysdeps/unix/bsd/ultrix4/mips/start.S b/sysdeps/unix/bsd/ultrix4/mips/start.S index ec0f9d8..eec8ce0 100644 --- a/sysdeps/unix/bsd/ultrix4/mips/start.S +++ b/sysdeps/unix/bsd/ultrix4/mips/start.S @@ -18,13 +18,6 @@ Cambridge, MA 02139, USA. */ #include -#ifndef HAVE_WEAK_SYMBOLS -#define __environ environ -#else -weak_alias (__environ, environ) -#endif - -.comm __environ, 4 .comm errno, 4 ENTRY(__start) diff --git a/sysdeps/unix/start.c b/sysdeps/unix/start.c index feb5f44..62c9bd9 100644 --- a/sysdeps/unix/start.c +++ b/sysdeps/unix/start.c @@ -35,11 +35,8 @@ weak_alias (__data_start, data_start) #define DECL_DUMMIES #endif -VOLATILE int errno; - -#ifndef HAVE_WEAK_SYMBOLS -#undef environ -#define __environ environ +#ifndef errno +volatile int errno; #endif extern void EXFUN(__libc_init, (int argc, char **argv, char **envp)); @@ -66,11 +63,10 @@ DEFUN_VOID(_start) start1(); } -#if !defined (NO_UNDERSCORES) && defined (HAVE_GNU_LD) && !defined (__GNUC__) +#if !defined (NO_UNDERSCORES) && defined (HAVE_WEAK_SYMBOLS) /* Make an alias called `start' (no leading underscore, so it can't conflict with C symbols) for `_start'. */ -asm(".stabs \"start\",11,0,0,0"); -asm(".stabs \"__start\",1,0,0,0"); +asm (".weak start; start = _start"); #endif #endif -- cgit v1.1
