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/combine-cmp-shift.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/combine-cmp-shift.c (limited to 'gcc/testsuite/gcc.target/arm/combine-cmp-shift.c') diff --git a/gcc/testsuite/gcc.target/arm/combine-cmp-shift.c b/gcc/testsuite/gcc.target/arm/combine-cmp-shift.c new file mode 100644 index 000000000..a64f20e06 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/combine-cmp-shift.c @@ -0,0 +1,16 @@ +/* { dg-skip-if "incompatible options" { arm*-*-* } { "-march=*" } { "-march=armv7-a" } } */ +/* { dg-options "-O2 -mcpu=cortex-a8" } */ +/* { dg-final { scan-assembler "cmp\tr\[0-9\]*, r\[0-9\]*, asr #31" } } */ + +typedef int SItype __attribute__ ((mode (SI))); +typedef int DItype __attribute__ ((mode (DI))); +void abort (void); + +SItype +__mulvsi3 (SItype a, SItype b) +{ + const DItype w = (DItype) a * (DItype) b; + if ((SItype) (w >> (4 * 8)) != (SItype) w >> ((4 * 8) - 1)) + abort (); + return w; +} -- cgit v1.2.3
