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.dg/tree-ssa/ifc-pr44710.c | 44 +++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ifc-pr44710.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ifc-pr44710.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ifc-pr44710.c b/gcc/testsuite/gcc.dg/tree-ssa/ifc-pr44710.c new file mode 100644 index 000000000..d4a1be8f0 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ifc-pr44710.c @@ -0,0 +1,44 @@ +/* { dg-do compile } */ +/* { dg-options "-c -O2 -ftree-vectorize" { target *-*-* } } */ + +#include +#include + +#define N 64 +float arr[N]; + +__attribute__ ((noinline)) +int foo (unsigned int n, float *min) +{ + unsigned int pos = 1; + unsigned int i; + float limit = N+N; + + for (i = 0; i < N; i++) + if (arr[i] < limit) + { + pos = i + 1; + limit = arr[i]; + } + + *min = limit; + return pos; +} + +int main (void) +{ + int i, pos; + float min; + + for (i = 0; i < N; i++) + arr[i] = (float)(i); + + arr[2] = -5.8; + + pos = foo (N, &min); + if (pos != 3 || min != arr[2]) + abort (); + + return 0; +} + -- cgit v1.2.3
