From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.target/arm/mmx-1.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/mmx-1.c (limited to 'gcc/testsuite/gcc.target/arm/mmx-1.c') diff --git a/gcc/testsuite/gcc.target/arm/mmx-1.c b/gcc/testsuite/gcc.target/arm/mmx-1.c new file mode 100644 index 000000000..c2eca7f78 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/mmx-1.c @@ -0,0 +1,24 @@ +/* Verify that if IP is saved to ensure stack alignment, we don't load + it into sp. */ +/* { dg-do compile } */ +/* { dg-skip-if "Test is specific to the iWMMXt" { arm*-*-* } { "-mcpu=*" } { "-mcpu=iwmmxt" } } */ +/* { dg-skip-if "Test is specific to the iWMMXt" { arm*-*-* } { "-mabi=*" } { "-mabi=iwmmxt" } } */ +/* { dg-skip-if "Test is specific to the iWMMXt" { arm*-*-* } { "-march=*" } { "-march=iwmmxt" } } */ +/* { dg-options "-O -mno-apcs-frame -mcpu=iwmmxt -mabi=iwmmxt" } */ +/* { dg-require-effective-target arm32 } */ +/* { dg-require-effective-target arm_iwmmxt_ok } */ +/* { dg-final { scan-assembler "ldmfd\[ ]sp!.*ip,\[ ]*pc" } } */ + +/* This function uses all the call-saved registers, namely r4, r5, r6, + r7, r8, r9, sl, fp.
