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/extzvsi.c | 41 +++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/extzvsi.c (limited to 'gcc/testsuite/gcc.c-torture/execute/extzvsi.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/extzvsi.c b/gcc/testsuite/gcc.c-torture/execute/extzvsi.c new file mode 100644 index 000000000..81f16185d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/extzvsi.c @@ -0,0 +1,41 @@ +/* The bit-field below would have a problem if __INT_MAX__ is too + small. */ +#if __INT_MAX__ < 2147483647 +int +main (void) +{ + exit (0); +} +#else +/* Failed on powerpc due to bad extzvsi pattern. */ + +struct ieee +{ + unsigned int negative:1; + unsigned int exponent:11; + unsigned int mantissa0:20; + unsigned int mantissa1:32; +} x; + +unsigned int +foo (void) +{ + unsigned int exponent; + + exponent = x.exponent; + if (exponent == 0) + return 1; + else if (exponent > 1) + return 2; + return 0; +} + +int +main (void) +{ + x.exponent = 1; + if (foo () != 0) + abort (); + return 0; +} +#endif -- cgit v1.2.3
