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/g2.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/g2.c (limited to 'gcc/testsuite/gcc.target/arm/g2.c') diff --git a/gcc/testsuite/gcc.target/arm/g2.c b/gcc/testsuite/gcc.target/arm/g2.c new file mode 100644 index 000000000..031b93657 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/g2.c @@ -0,0 +1,20 @@ +/* Verify that hardware multiply is preferred on XScale. */ +/* { dg-do compile } */ +/* { dg-options "-mcpu=xscale -O2" } */ +/* { dg-skip-if "Test is specific to the Xscale" { arm*-*-* } { "-march=*" } { "-march=xscale" } } */ +/* { dg-require-effective-target arm32 } */ + +/* Brett Gaines' test case. */ +unsigned BCPL(unsigned) __attribute__ ((naked)); +unsigned BCPL(unsigned seed) +{ + /* Best code would be: + ldr r1, =2147001325 + ldr r2, =715136305 + mla r0, r1, r0, r2 + mov pc, lr */ + + return seed * 2147001325U + 715136305U; +} + +/* { dg-final { scan-assembler "mla\[ ].*" } } */ -- cgit v1.2.3
