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.target/cris/torture/pr34773.c | 74 +++++++++++++++++++++++++ 1 file changed, 74 insertions(+) create mode 100644 gcc/testsuite/gcc.target/cris/torture/pr34773.c (limited to 'gcc/testsuite/gcc.target/cris/torture/pr34773.c') diff --git a/gcc/testsuite/gcc.target/cris/torture/pr34773.c b/gcc/testsuite/gcc.target/cris/torture/pr34773.c new file mode 100644 index 000000000..d3723e38f --- /dev/null +++ b/gcc/testsuite/gcc.target/cris/torture/pr34773.c @@ -0,0 +1,74 @@ +/* { dg-do run } */ +union double_union +{ + double d; + int i[2]; +}; +void _dtoa_r (double) __attribute__ ((__noinline__)); +void _vfprintf_r (double) __attribute__ ((__noinline__)); +void +__sprint_r(int); +void +_vfprintf_r(double da) +{ + double ffp = da; + double value = ffp; + union double_union tmp; + + tmp.d = value; + + if ((tmp.i[1]) & ((unsigned)0x80000000L)) { + value = -value; + } + + _dtoa_r (value); + + if (ffp != 0) + __sprint_r(value == 0); + __asm__ (""); +} + + +double dd = -.012; +double ff = .012; + +void exit (int) __attribute__ ((__noreturn__)); +void abort (void) __attribute__ ((__noreturn__)); +void *memset(void *s, int c, __SIZE_TYPE__ n); +void _dtoa_r (double d) +{ + if (d != ff) + abort (); + __asm__ (""); +} + +void __sprint_r (int i) +{ + if (i != 0) + abort (); + __asm__ (""); +} + +int clearstack (void) __attribute__ ((__noinline__)); +int clearstack (void) +{ + char doodle[128]; + memset (doodle, 0, sizeof doodle); + __asm__ volatile ("" : : "g" (doodle) : "memory"); + return doodle[127]; +} + +void doit (void) __attribute__ ((__noinline__)); +void doit (void) +{ + _vfprintf_r (dd); + _vfprintf_r (ff); + __asm__ (""); +} + +int main(void) +{ + clearstack (); + doit (); + exit (0); +} -- cgit v1.2.3
