From 48252123bcf7a2ceed907a51fea74897fd601769 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 27 Nov 1998 11:34:40 +0000 Subject: Update. 1998-09-03 Philip Blundell * sysdeps/arm/bits/endian.h (__FLOAT_WORD_ORDER): Define to big endian. * math/math_private.h: Use __FLOAT_WORD_ORDER rather than BYTE_ORDER. * string/endian.h: If __FLOAT_WORD_ORDER wasn't defined by , make it the same as __BYTE_ORDER. 1998-11-27 Ulrich Drepper * math/math.h: Avoid using long double functions in generic macros if __NO_LONG_DOUBLE_MATH. * sysdeps/arm/dl-machine.h: Fix handling of weak undefined symbols during bootstrapping. * scripts/config.sub: Add Netwinder specific matches. Patch by Scott Bambrough . 1998-11-26 Andreas Schwab * Makeconfig ($(common-objpfx)sysd-dirs): Use automatic variables if possible. ($(common-objpfx)sysd-sorted): Likewise. 1998-11-27 Andreas Jaeger * sysdeps/libm-ieee754/e_log.c (__ieee754_log): Add declaration of local variables t1,t2 only if needed. * sysdeps/libm-ieee754/e_atan2.c: Added braces to avoid compiler warnings. * sysdeps/libm-ieee754/s_truncf.c (__truncf): Likewise. * sysdeps/libm-ieee754/s_trunc.c (__trunc): Likewise. * sysdeps/mips/mul_1.S (Loop): Add closing comment to avoid warning. 1998-11-27 Andreas Jaeger * math/math.h: Add brace to correct #if expression. --- sysdeps/arm/bits/endian.h | 3 ++- sysdeps/arm/dl-machine.h | 8 +++++++- 2 files changed, 9 insertions(+), 2 deletions(-) (limited to 'sysdeps/arm') diff --git a/sysdeps/arm/bits/endian.h b/sysdeps/arm/bits/endian.h index ad3b539..7fe486e 100644 --- a/sysdeps/arm/bits/endian.h +++ b/sysdeps/arm/bits/endian.h @@ -1,7 +1,8 @@ -/* ARM is little-endian. */ +/* ARM is (usually) little-endian but with a big-endian FPU. */ #ifndef _ENDIAN_H # error "Never use directly; include instead." #endif #define __BYTE_ORDER __LITTLE_ENDIAN +#define __FLOAT_WORD_ORDER __BIG_ENDIAN diff --git a/sysdeps/arm/dl-machine.h b/sysdeps/arm/dl-machine.h index 66ab4c6..53aa806 100644 --- a/sysdeps/arm/dl-machine.h +++ b/sysdeps/arm/dl-machine.h @@ -416,7 +416,13 @@ elf_machine_rel (struct link_map *map, const Elf32_Rel *reloc, break; case R_ARM_GLOB_DAT: case R_ARM_JUMP_SLOT: - *reloc_addr = value; +#ifdef RTLD_BOOTSTRAP + /* Fix weak undefined references. */ + if (sym != NULL && sym->st_value == 0) + *reloc_addr = 0; + else +#endif + *reloc_addr = value; break; case R_ARM_ABS32: { -- cgit v1.1
