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/floatunsisf-1.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/floatunsisf-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/floatunsisf-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/floatunsisf-1.c b/gcc/testsuite/gcc.c-torture/execute/floatunsisf-1.c new file mode 100644 index 000000000..cc4c49bbe --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/floatunsisf-1.c @@ -0,0 +1,21 @@ +/* The fp-bit.c function __floatunsisf had a latent bug where guard bits + could be lost leading to incorrect rounding. */ +/* Origin: Joseph Myers */ + +extern void abort (void); +extern void exit (int); +#if __INT_MAX__ >= 0x7fffffff +volatile unsigned u = 0x80000081; +#else +volatile unsigned long u = 0x80000081; +#endif +volatile float f1, f2; +int +main (void) +{ + f1 = (float) u; + f2 = (float) 0x80000081; + if (f1 != f2) + abort (); + exit (0); +} -- cgit v1.2.3
