* guard *_chk() related stuff with UCLIBC_HAS_FORTIFYPeter S. Mazinger2011-03-092-7/+3
| | | | | | | | | | | | Guard x86_64 memset_chk/memcpy_chk be guarded by UCLIBC_HAS_FORTIFY. Compile ssp.c if one of SSP/FORTIFY is defined. Guard __chk_fail() with UCLIBC_HAS_FORTIFY and move its prototype to libc-internal.h. Disable _FORTIFY_SOURCE if UCLIBC_HAS_FORTIFY is not set. The config option itself is omitted on purpose, headers need to be reviewed and generic *_chk() functions need to be first provided. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
* x86_64: fix multiple definition of chk functionsAustin Foxley2009-12-194-1/+7

* build: Get rids of PIC macro using compiler flag __PIC__ insteadCarmelo Amoroso2009-12-162-3/+3
| | | | | | | Based on Peter Mazinger's comments on a recent commit, I decided to get rids of all occurrences of PIC changing them to __PIC__ Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* amd64 string ops: use alignment more carefully, and comment it.Denis Vlasenko2008-04-158-30/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By capping max padding to not be bigger than three next insns, we avoid having ridiculously big NOPs like this one: 53:66 66 66 66 2e 0f 1f nopw %cs:0x0(%rax,%rax,1) 5a:84 00 00 00 00 00 which was bigger than next three insns combined! Size changes: text data bss dec hex filename 102 0 0 102 66 x86_64/memcpy.o 102 0 0 102 66 x86_64.old/memcpy.o 90 0 0 90 5a x86_64/mempcpy.o 102 0 0 102 66 x86_64.old/mempcpy.o 210 0 0 210 d2 x86_64/memset.o 242 0 0 242 f2 x86_64.old/memset.o 213 0 0 213 d5 x86_64/stpcpy.o 220 0 0 220 dc x86_64.old/stpcpy.o 428 0 0 428 1ac x86_64/strcat.o 444 0 0 444 1bc x86_64.old/strcat.o 417 0 0 417 1a1 x86_64/strchr.o 418 0 0 418 1a2 x86_64.old/strchr.o 33 0 0 33 21 x86_64/strcmp.o 33 0 0 33 21 x86_64.old/strcmp.o 213 0 0 213 d5 x86_64/strcpy.o 220 0 0 220 dc x86_64.old/strcpy.o 135 0 0 135 87 x86_64/strcspn.o 151 0 0 151 97 x86_64.old/strcspn.o 225 0 0 225 e1 x86_64/strlen.o 233 0 0 233 e9 x86_64.old/strlen.o 140 0 0 140 8c x86_64/strpbrk.o 156 0 0 156 9c x86_64.old/strpbrk.o 135 0 0 135 87 x86_64/strspn.o 151 0 0 151 97 x86_64.old/strspn.o Also, a few files got their .text alignment relaxed from 16 to 8 bytes, which reduces padding at link time.
