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/c99-const-expr-13.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c99-const-expr-13.c (limited to 'gcc/testsuite/gcc.dg/c99-const-expr-13.c') diff --git a/gcc/testsuite/gcc.dg/c99-const-expr-13.c b/gcc/testsuite/gcc.dg/c99-const-expr-13.c new file mode 100644 index 000000000..0ee525bec --- /dev/null +++ b/gcc/testsuite/gcc.dg/c99-const-expr-13.c @@ -0,0 +1,15 @@ +/* Test for constant expressions: VLA size constraints with + -frounding-math. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1999 -pedantic-errors -frounding-math" } */ + +void +f (void) +{ + /* With -frounding-math, presume that floating-point expressions + that may depend on the rounding mode do not count as arithmetic + constant expressions, and so arrays involving such expressions in + their sizes do not have the size checked for being negative. */ + int a1[(int)(-5.0/3.0)]; +} -- cgit v1.2.3
