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/g++.dg/eh/simd-5.C | 44 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/g++.dg/eh/simd-5.C (limited to 'gcc/testsuite/g++.dg/eh/simd-5.C') diff --git a/gcc/testsuite/g++.dg/eh/simd-5.C b/gcc/testsuite/g++.dg/eh/simd-5.C new file mode 100644 index 000000000..71e117ead --- /dev/null +++ b/gcc/testsuite/g++.dg/eh/simd-5.C @@ -0,0 +1,44 @@ +// Test EH with V2SI SIMD registers actually restores correct values. +// Origin: Joseph Myers +// { dg-options "-O" } +// { dg-do run { target { powerpc_spe && { ! *-*-vxworks* } } } } + +extern "C" void abort (void); +extern "C" int memcmp (const void *, const void *, __SIZE_TYPE__); +typedef int __attribute__((vector_size (8))) v2si; + +v2si a = { 1, 2 }; +v2si b = { 3, 4 }; +v2si c = { 4, 6 }; +volatile v2si r; +v2si r2; + +void +f () +{ + register v2si v asm("r15"); + v = __builtin_spe_evaddw (b, c); + asm volatile ("" : "+r" (v)); + r = v; + throw 1; +} + +int +main () +{ + register v2si v asm("r15"); + v = __builtin_spe_evaddw (a, b); + asm volatile ("" : "+r" (v)); + try + { + f (); + } + catch (int) + { + r = v; + r2 = r; + if (memcmp (&r2, &c, sizeof (v2si))) + abort (); + } + return 0; +} -- cgit v1.2.3
