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/pr36227.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr36227.c (limited to 'gcc/testsuite/gcc.dg/pr36227.c') diff --git a/gcc/testsuite/gcc.dg/pr36227.c b/gcc/testsuite/gcc.dg/pr36227.c new file mode 100644 index 000000000..27fe00155 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr36227.c @@ -0,0 +1,22 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -Wstrict-overflow=3" } */ +#if (__SIZEOF_LONG_LONG__ == __SIZEOF_POINTER__) +typedef unsigned long long ptrcast; +#elif (__SIZEOF_LONG__ == __SIZEOF_POINTER__) +typedef unsigned long ptrcast; +#elif (__SIZEOF_INT__ == __SIZEOF_POINTER__) +typedef unsigned int ptrcast; +#else +#error Add target support here +#endif + +volatile unsigned long * +sat_add(volatile unsigned long *ptr, unsigned long i, volatile unsigned long *end) +{ + if ((ptrcast)ptr + i * sizeof(*ptr) > (ptrcast)ptr) /* { dg-bogus "pointer wraparound" } */ + return ptr + i; + else + return end; +} + + -- cgit v1.2.3
