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/pr47881.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr47881.c (limited to 'gcc/testsuite/gcc.dg/pr47881.c') diff --git a/gcc/testsuite/gcc.dg/pr47881.c b/gcc/testsuite/gcc.dg/pr47881.c new file mode 100644 index 000000000..ee1707342 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr47881.c @@ -0,0 +1,24 @@ +/* PR debug/47881 */ +/* { dg-do compile } */ +/* { dg-options "-O -fcompare-debug -fno-dce -funroll-loops -fno-web" } */ + +extern int data[]; + +int +foo (int *t, int *f, int n) +{ + int i = 0, a, b, c, d; + while (data[*f] && n) + n--; + for (; i < n; i += 4) + { + a = data[*(f++) & 0x7f]; + c = data[*(f++) & 0x7f]; + c = data[*(f++) & 0x7f]; + d = data[*(f++) & 0x7f]; + if ((a & 0x80) || (b & 0x80) || (c & 0x80) || (d & 0x80)) + return 1; + *(t++) = 16; + } + return 0; +} -- cgit v1.2.3
