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.dg/struct/wo_prof_single_str_pointer.c | 40 ++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/struct/wo_prof_single_str_pointer.c (limited to 'gcc/testsuite/gcc.dg/struct/wo_prof_single_str_pointer.c') diff --git a/gcc/testsuite/gcc.dg/struct/wo_prof_single_str_pointer.c b/gcc/testsuite/gcc.dg/struct/wo_prof_single_str_pointer.c new file mode 100644 index 000000000..bd70dfb63 --- /dev/null +++ b/gcc/testsuite/gcc.dg/struct/wo_prof_single_str_pointer.c @@ -0,0 +1,40 @@ +/* { dg-do compile } */ +/* { dg-do run } */ + +#include +typedef struct +{ + int a; + int *b; +}str_t; + +#define N 3 + +str_t *p; + +int +main () +{ + str_t str; + int i; + int res = 1 << (1 << N); + p = &str; + str.a = 2; + + p->b = &(p->a); + + for (i=0; i < N; i++) + p->a = *(p->b)*(*(p->b)); + + if (p->a != res) + abort (); + + /* POSIX ignores all but the 8 low-order bits, but other + environments may not. */ + return (p->a & 255); +} + +/*--------------------------------------------------------------------------*/ +/* The access &(p->a) is handled incorrectly in ipa-struct-reorg.c. */ +/* { dg-final { scan-ipa-dump "Number of structures to transform is 1" "ipa_struct_reorg" { xfail *-*-* } } } */ +/* { dg-final { cleanup-ipa-dump "*" } } */ -- cgit v1.2.3
