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.c-torture/execute/builtins/strlen-2.c | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/strlen-2.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/strlen-2.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/strlen-2.c b/gcc/testsuite/gcc.c-torture/execute/builtins/strlen-2.c new file mode 100644 index 000000000..e15ad6636 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/strlen-2.c @@ -0,0 +1,41 @@ +/* Copyright (C) 2003 Free Software Foundation. + + Test strlen optimizations on conditional expressions. + + Written by Jakub Jelinek, June 23, 2003. */ + +typedef __SIZE_TYPE__ size_t; +extern size_t strlen (const char *); +extern char *strcpy (char *, const char *); +extern int memcmp (const void *, const void *, size_t); +extern void abort (void); +extern int inside_main; + +size_t g, h, i, j, k, l; + +size_t +foo (void) +{ + if (l) + abort (); + return ++l; +} + +void +main_test (void) +{ + if (strlen (i ?
