From bcd5e8e3f9a46d151ed8ca69d7c250e11dff67ce Mon Sep 17 00:00:00 2001 From: Marcus Shawcroft Date: Tue, 10 Nov 2015 14:08:42 +0000 Subject: [ARM] Adding strlen.S The patch adds strlen.S to contain the complementary preprocessor logic to strlen-stub.c intended to provide #inclusion of alternative .S implementations. Initially we just include the existing strlen-armv7.S implementation. We rewrite _ISA_ARMV7 in both strlen.S and strlen-stub.c to use the underlying existing underlying defintion from arm_asm.h in order to avoide including that file, this is in effect the first step towards a move to ACLE predefines only. Tested by building newlib and comparing libc.a binaries before and after for all permutations of: Architectures: armv4 armv4t armv5 armv5t armv5te armv6 armv6j armv6k armv6z armv6kz armv6t2 armv6-m armv6s-m armv7 armv7-a armv7ve armv7-r armv7-m armv7e-m armv8-a iwmmxt iwmmxt2 ISAs: thumb arm Optimization Levels: Os O2 Excluding: armv6s-m -mthumb armv6-m -mthumb armv6zk -mthumb armv6z -mthumb armv6k -mthumb armv6j -mthumb --- newlib/ChangeLog | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'newlib/ChangeLog') diff --git a/newlib/ChangeLog b/newlib/ChangeLog index 7c2f38aa3..44dfdcdce 100644 --- a/newlib/ChangeLog +++ b/newlib/ChangeLog @@ -1,3 +1,11 @@ +2015-11-13 Marcus Shawcroft + + * libc/machine/arm/Makefile.am: Adding strlen.S. + * libc/machine/arm/Makefile.in: Regenerate. + * libc/machine/arm/strlen.S: New. + * libc/machine/arm/strlen-stub.c: Rewrite #if condition. + * libc/machine/arm/strlen-armv7.S: Remove surrounding #if. + 2015-11-13 Marcus Shawcroft * libc/machine/arm/Makefile.am: Rename strlen.c to strlen-stub.c -- cgit v1.2.3
