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/wmul-1.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/wmul-1.c (limited to 'gcc/testsuite/gcc.target/arm/wmul-1.c') diff --git a/gcc/testsuite/gcc.target/arm/wmul-1.c b/gcc/testsuite/gcc.target/arm/wmul-1.c new file mode 100644 index 000000000..426c9393f --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/wmul-1.c @@ -0,0 +1,19 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target arm_dsp } */ +/* { dg-options "-O2" } */ + +int mac(const short *a, const short *b, int sqr, int *sum) +{ + int i; + int dotp = *sum; + + for (i = 0; i < 150; i++) { + dotp += b[i] * a[i]; + sqr += b[i] * b[i]; + } + + *sum = dotp; + return sqr; +} + +/* { dg-final { scan-assembler-times "smlabb" 2 } } */ -- cgit v1.2.3
