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/powerpc/rs6000-power2-1.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/rs6000-power2-1.c (limited to 'gcc/testsuite/gcc.target/powerpc/rs6000-power2-1.c') diff --git a/gcc/testsuite/gcc.target/powerpc/rs6000-power2-1.c b/gcc/testsuite/gcc.target/powerpc/rs6000-power2-1.c new file mode 100644 index 000000000..375241ec6 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/rs6000-power2-1.c @@ -0,0 +1,21 @@ +/* { dg-do compile { target { ilp32 } } } */ +/* { dg-options "-O3 -mcpu=power2 -fno-schedule-insns -w -mhard-float" } */ +/* This used to ICE as the peephole was not checking to see + if the register is a floating point one (I think this cannot + happen in real life except in this example). */ + +register volatile double t1 __asm__("r14"); +register volatile double t2 __asm__("r15"); +register volatile double t3 __asm__("r16"), t4 __asm__("r17"); +void t(double *a, double *b) +{ + t1 = a[-1]; + t2 = a[0]; + t3 = a[1]; + t4 = a[2]; + b[-1] = t1; + b[0] = t2; + b[1] = t3; + b[2] = t4; +} + -- cgit v1.2.3
