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/execute/921204-1.c | 46 ++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/921204-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/921204-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/921204-1.c b/gcc/testsuite/gcc.c-torture/execute/921204-1.c new file mode 100644 index 000000000..a7bba830a --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/921204-1.c @@ -0,0 +1,46 @@ +/* The bit-field below would have a problem if __INT_MAX__ is too + small. */ +#if __INT_MAX__ < 2147483647 +int +main (void) +{ + exit (0); +} +#else +typedef struct { + unsigned b0:1, f1:17, b18:1, b19:1, b20:1, f2:11; +} bf; + +typedef union { + bf b; + unsigned w; +} bu; + +bu +f(bu i) +{ + bu o = i; + + if (o.b.b0) + o.b.b18 = 1, + o.b.b20 = 1; + else + o.b.b18 = 0, + o.b.b20 = 0; + + return o; +} + +main() +{ + bu a; + bu r; + + a.w = 0x4000000; + a.b.b0 = 0; + r = f(a); + if (a.w != r.w) + abort(); + exit(0); +} +#endif -- cgit v1.2.3
