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/pr46614.c | 56 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr46614.c (limited to 'gcc/testsuite/gcc.dg/pr46614.c') diff --git a/gcc/testsuite/gcc.dg/pr46614.c b/gcc/testsuite/gcc.dg/pr46614.c new file mode 100644 index 000000000..8e757803e --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr46614.c @@ -0,0 +1,56 @@ +/* PR rtl-optimization/46614 */ +/* { dg-do run } */ +/* { dg-options "-O -fno-rename-registers -fsched2-use-superblocks -fschedule-insns2 -funroll-loops" } */ + +extern void abort (void); + +struct S +{ + unsigned char a; + unsigned char b; + unsigned int c; + unsigned int e; + unsigned char f; + unsigned int g; +}; + +void bar (struct S *x) +{ + int i; + struct S *p = x; + struct S r[16]; + unsigned j; + for (i = 0; i < 16; i++) + { + r[i].c = p->b + p->c; + j = p->c + p->f; + r[i].a = j + p->b; + r[i].f = p->f + p->e; + r[i].g = p->b + p->c; + } + for (i = 0; i < 16; i++) + { + if (r[i].c != x[i].b + x[i].c + || r[i].a != x[i].c + x[i].f + x[i].b + || r[i].f != x[i].f + x[i].e + || r[i].g != x[i].b + x[i].c) + abort (); + } + for (i = 0; i < 16; i++) + { + r[i].b = p->c; + if (r[i].b != x[i].c) + abort (); + } +} + +int +main () +{ + int i; + struct S x[16]; + for (i = 0; i < 16; i++) + x[i].b = x[i].c = x[i].e = x[i].f = 5; + bar (x); + return 0; +} -- cgit v1.2.3
