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/builtins-13.c | 62 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtins-13.c (limited to 'gcc/testsuite/gcc.dg/builtins-13.c') diff --git a/gcc/testsuite/gcc.dg/builtins-13.c b/gcc/testsuite/gcc.dg/builtins-13.c new file mode 100644 index 000000000..149407b54 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtins-13.c @@ -0,0 +1,62 @@ +/* Copyright (C) 2003 Free Software Foundation. + + Verify that the malloc-like __builtin_ allocation functions are + correctly aliased by the compiler. + + Written by Roger Sayle, 12th April 2003. */ + +/* { dg-do link } */ +/* { dg-options "-ansi" } */ + +typedef __SIZE_TYPE__ size_t; + +extern void abort (void); +extern void *malloc (size_t); +extern void *calloc (size_t,size_t); + +extern void link_error (void); + +static int x; + +void test1(void) +{ + int *ptr1, *ptr2; + + ptr1 = &x; + ptr2 = (int*) malloc (sizeof (int)); + + *ptr1 = 12; + *ptr2 = 8; + + if (*ptr1 != 12) + link_error(); +} + +void test2(void) +{ + int *ptr1, *ptr2; + + ptr1 = &x; + ptr2 = (int*) calloc (1, sizeof (int)); + + *ptr1 = 12; + *ptr2 = 8; + + if (*ptr1 != 12) + link_error (); +} + +int main() +{ + test1 (); + test2 (); + return 0; +} + +#ifndef __OPTIMIZE__ +void link_error (void) +{ + abort (); +} +#endif + -- cgit v1.2.3
