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/20031220-2.c | 44 ++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20031220-2.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20031220-2.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20031220-2.c b/gcc/testsuite/gcc.c-torture/compile/20031220-2.c new file mode 100644 index 000000000..45c827794 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20031220-2.c @@ -0,0 +1,44 @@ +/* PR target/12749 + Orgin: Matt Thomas + This used to cause GCC to write out an instruction for i386 when using a L64 host + which gas could not handle because GCC would write a full 64bit hex string out. */ + + +float fabsf (float); +typedef int __int32_t; +typedef unsigned int __uint32_t; +typedef union +{ + float value; + __uint32_t word; +} ieee_float_shape_type; +extern float __ieee754_expf (float); +extern float __ieee754_sinhf (float); +static const float one = 1.0, shuge = 1.0e37; +float +__ieee754_sinhf(float x) +{ + float t,w,h; + __int32_t ix,jx; + do { ieee_float_shape_type gf_u; gf_u.value = (x); (jx) = gf_u.word; } while (0); + ix = jx&0x7fffffff; + if(ix>=0x7f800000) return x+x; + h = 0.5; + if (jx<0) h = -h; + if (ix < 0x41b00000) { + if (ix<0x31800000) + if(shuge+x>one) return x; + t = expm1f(fabsf(x)); + if(ix<0x3f800000) return h*((float)2.0*t-t*t/(t+one)); + return h*(t+t/(t+one)); + } + if (ix < 0x42b17180) return h*__ieee754_expf(fabsf(x)); + if (ix<=0x42b2d4fc) { + w = __ieee754_expf((float)0.5*fabsf(x)); + t = h*w; + return t*w; + } + return x*shuge; +} + + -- cgit v1.2.3
