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/torture/pr26587.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr26587.c (limited to 'gcc/testsuite/gcc.dg/torture/pr26587.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr26587.c b/gcc/testsuite/gcc.dg/torture/pr26587.c new file mode 100644 index 000000000..ad5d60f3a --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr26587.c @@ -0,0 +1,29 @@ +/* { dg-do run } */ +/* { dg-require-effective-target int32plus } */ + +extern void abort(void); +typedef unsigned int BF_word; +typedef BF_word BF_key[16 + 2]; +static struct { + BF_key P; +} BF_current; +int main(void) +{ + BF_word L; + BF_word tmp4, *ptr; + BF_word i; + for (i = 0; i < 16 + 2; i++) + BF_current.P[i] = i * 0x98765432; + L = 0; + ptr = BF_current.P; + do { + ptr += 2; + L ^= BF_current.P[0]; + tmp4 = L >> 24; + L = tmp4 ^ BF_current.P[16 + 1]; + *(ptr - 2) = L; + } while (ptr < &BF_current.P[16 + 2]); + if (L != 0x1fdb9752) + abort(); + return 0; +} -- cgit v1.2.3
