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/g++.dg/warn/pr30636.C | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/pr30636.C (limited to 'gcc/testsuite/g++.dg/warn/pr30636.C') diff --git a/gcc/testsuite/g++.dg/warn/pr30636.C b/gcc/testsuite/g++.dg/warn/pr30636.C new file mode 100644 index 000000000..32ce6edbd --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/pr30636.C @@ -0,0 +1,17 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -Warray-bounds" } */ + +typedef char one_buffer[512]; +static one_buffer emergency_buffer[4]; + +void free_exception (void *vptr) +{ + char *base = (char *) &emergency_buffer[0][0]; + char *ptr = (char *) vptr; + if (ptr >= base && ptr < base + sizeof (emergency_buffer)) /* { dg-bogus "subscript" } */ + { + /* Do something. */ + __builtin_exit (0); + } +} + -- cgit v1.2.3
