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.c-torture/compile/pr39041.c | 28 +++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr39041.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr39041.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr39041.c b/gcc/testsuite/gcc.c-torture/compile/pr39041.c new file mode 100644 index 000000000..cc58a8a37 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr39041.c @@ -0,0 +1,28 @@ +int test_bit(int nr, void *addr) +{ + int *a = (int *)addr; + int mask; + a += nr; + mask = 1 << nr; + return mask & *a; +} +struct { + struct { + int disabled; + } *data[1]; +} trace; +struct { + unsigned bits[1]; +} cpumask; +void inc(int *); +void dec(int *); +int foo(void) +{ + int cpu; + for (cpu = 0; cpu < 1; cpu++) { + if (test_bit(cpu, cpumask.bits)) + inc(&trace.data[cpu]->disabled); + if (!test_bit(cpu, cpumask.bits)) + dec(&trace.data[cpu]->disabled); + } +} -- cgit v1.2.3
