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/vect/pr42604.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/pr42604.c (limited to 'gcc/testsuite/gcc.dg/vect/pr42604.c') diff --git a/gcc/testsuite/gcc.dg/vect/pr42604.c b/gcc/testsuite/gcc.dg/vect/pr42604.c new file mode 100644 index 000000000..14f255a40 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/pr42604.c @@ -0,0 +1,35 @@ +/* PR debug/42604 */ +/* { dg-do compile } */ +/* { dg-options "-O3 -ftree-vectorize -g -ffast-math" } */ + +unsigned *d; +unsigned short e; +int f; +float h[3][4]; + +void +test (unsigned short *b) +{ + int a, c, i; + float g[3]; + unsigned j[32] = { 10, 0x63707274 }; + for (i = 0; i < (int) j[0]; i++) + { + j[i * 3 + 2] = d[0]; + d[0] += (j[i * 3 + 3] + 3) & -4; + } + for (a = 0; a < e; a++) + { + g[0] = g[1] = g[2] = 0; + for (c = 0; c < f; c++) + { + g[0] += h[0][c] * b[c]; + g[1] += h[1][c] * b[c]; + } + for (c = 0; c < 3; c++) + b[c] = 0 > ((int) g[c] < 65535 ?
