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/tree-ssa/pr38572.C | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr38572.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr38572.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr38572.C b/gcc/testsuite/g++.dg/tree-ssa/pr38572.C new file mode 100644 index 000000000..89d228f02 --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr38572.C @@ -0,0 +1,32 @@ +// PR tree-optimization/38572 +// { dg-do compile } +// { dg-options "-O2" } + +// Crash caused by the out-of-bounds enum values (all the remaining cruft +// is needed only to trigger the appropriate code path in tree-vrp.c). +enum JSOp +{ + JSOP_GETELEM = 5, + JSOP_LIMIT +}; +extern void g (); +void f (char *pc, char *endpc, int format, char ***fp, enum JSOp op) +{ + while (pc <= endpc) + { + if ((fp && *fp && pc == **fp) || pc == endpc) + { + if (format == 1) + op = (JSOp) 256; + else if (format == 2) + op = (JSOp) 257; + else + op = JSOP_GETELEM; + } + if (op >= JSOP_LIMIT) + { + if (format) + g (); + } + } +} -- cgit v1.2.3
