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/20080704-1.c | 43 ++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20080704-1.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20080704-1.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20080704-1.c b/gcc/testsuite/gcc.c-torture/compile/20080704-1.c new file mode 100644 index 000000000..b5e38b4ba --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20080704-1.c @@ -0,0 +1,43 @@ +/* This code used to crash fold_convert due to PRE + wanting to fold_convert from a REAL_TYPE to an INTEGER_TYPE. */ +typedef unsigned int uint32_t; +union double_union +{ + double d; + uint32_t i[2]; +}; +struct _Jv_reent +{ + int _errno; +}; +_Jv_strtod_r (struct _Jv_reent *ptr, char **se) +{ + int bb2, sign; + double aadj, aadj1, adj; + unsigned long y, z; + union double_union rv, *bs = ((void *) 0), *delta = ((void *) 0); + { + ovfl:ptr->_errno = 34; + { + (((uint32_t) 0xfffffL) | ((uint32_t) 0x100000L) * (1024 + 1023 - 1)); + } + if ((aadj = _Jv_ratio (delta, bs)) <= 2.) + { + { + if (aadj < 2. / 2) + aadj = 1. / 2; + aadj1 = -aadj; + } + } + { + (rv.i[1]) -= 53 * ((uint32_t) 0x100000L); + adj = aadj1 * _Jv_ulp (rv.d); + rv.d += adj; + if (((rv.i[1]) & ((uint32_t) 0x7ff00000L)) >= + ((uint32_t) 0x100000L) * (1024 + 1023 - 53)) + { + goto ovfl; + } + } + } +} -- cgit v1.2.3
