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/graphite/pr37943.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/graphite/pr37943.c (limited to 'gcc/testsuite/gcc.dg/graphite/pr37943.c') diff --git a/gcc/testsuite/gcc.dg/graphite/pr37943.c b/gcc/testsuite/gcc.dg/graphite/pr37943.c new file mode 100644 index 000000000..4513d12c0 --- /dev/null +++ b/gcc/testsuite/gcc.dg/graphite/pr37943.c @@ -0,0 +1,33 @@ +/* { dg-options "-O3 -fgraphite-identity -fdump-tree-graphite-all" } */ + +typedef struct +{ + int mode,state,num,state_out; + unsigned char* bits; + char *out; +}test; +unsigned char copy( test* s ) +{ + while(1) + { + if (s->mode == 0) break; + if (s->state_out >= s->num) break; + *(s->out) = s->bits[s->state_out]; + if (s->mode == 0) s->mode++; + } +} +unsigned char compress(test *in) +{ + unsigned char p_in, p_out; + while(1) + { + if (in->state == 1) + { + p_out |= copy(in); + if (in->state_out < in->num) break; + } + } + return p_in || p_out; +} +/* { dg-final { cleanup-tree-dump "graphite" } } */ + -- cgit v1.2.3
