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.c-torture/execute/pr34176.c | 68 +++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr34176.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr34176.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr34176.c b/gcc/testsuite/gcc.c-torture/execute/pr34176.c new file mode 100644 index 000000000..3bbdb22c7 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr34176.c @@ -0,0 +1,68 @@ + +typedef __SIZE_TYPE__ size_t; +typedef unsigned int index_ty; +typedef index_ty *index_list_ty; + +struct mult_index +{ + index_ty index; + unsigned int count; +}; + +struct mult_index_list +{ + struct mult_index *item; + size_t nitems; + size_t nitems_max; + + struct mult_index *item2; + size_t nitems2_max; +}; + +int __attribute__((noinline)) +hash_find_entry (size_t *result) +{ + *result = 2; + return 0; +} + +extern void abort (void); +struct mult_index * __attribute__((noinline)) +foo (size_t n) +{ + static count = 0; + if (count++ > 0) + abort (); + return 0; +} + +int +main (void) +{ + size_t nitems = 0; + + for (;;) + { + size_t list; + + hash_find_entry (&list); + { + size_t len2 = list; + struct mult_index *destptr; + struct mult_index *dest; + size_t new_max = nitems + len2; + + if (new_max != len2) + break; + dest = foo (new_max); + + destptr = dest; + while (len2--) + destptr++; + + nitems = destptr - dest; + } + } + + return 0; +} -- cgit v1.2.3
