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/opt/ptrintsum1.C | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/ptrintsum1.C (limited to 'gcc/testsuite/g++.dg/opt/ptrintsum1.C') diff --git a/gcc/testsuite/g++.dg/opt/ptrintsum1.C b/gcc/testsuite/g++.dg/opt/ptrintsum1.C new file mode 100644 index 000000000..a6a3c9727 --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/ptrintsum1.C @@ -0,0 +1,29 @@ +// PR c++/4401 +// This testcase was miscompiled on 64-bit platforms, resulting to +// operating on a[0x100000000] instead of a[0]. +// { dg-do run } +// { dg-options "-O2" } + +char *a; +char b[] = "AAAA"; + +extern "C" void abort (void); +extern "C" void exit (int); + +void foo (void) +{ + unsigned int i, j; + + i = 2; + j = 3; + a[i + 1 - j] += i; +} + +int main (void) +{ + a = b; + foo (); + if (b[0] != 'A' + 2) + abort (); + exit (0); +} -- cgit v1.2.3
