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.dg/float-range-5.c | 44 ++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/float-range-5.c (limited to 'gcc/testsuite/gcc.dg/float-range-5.c') diff --git a/gcc/testsuite/gcc.dg/float-range-5.c b/gcc/testsuite/gcc.dg/float-range-5.c new file mode 100644 index 000000000..034f36058 --- /dev/null +++ b/gcc/testsuite/gcc.dg/float-range-5.c @@ -0,0 +1,44 @@ +/* PR 23572 : warnings for out of range floating-point constants + Test that they are NOT pedantic warnings. */ +/* { dg-do compile } */ +/* { dg-options "-pedantic-errors -std=c99" } */ +/* { dg-skip-if "No Inf support" { spu-*-* } } */ +#include + +#ifndef INFINITY +#define INFINITY (__builtin_inff ()) +#endif + +void overflow(void) +{ + float f1 = 3.5E+38f; /* { dg-warning "floating constant exceeds range" } */ + float f2 = -3.5E+38f; /* { dg-warning "floating constant exceeds range" } */ + float f3 = INFINITY; + float f4 = -INFINITY; + + double d1 = 1.9E+308; /* { dg-warning "floating constant exceeds range" } */ + double d2 = -1.9E+308; /* { dg-warning "floating constant exceeds range" } */ + double d3 = INFINITY; + double d4 = -INFINITY; +} + +void underflow(void) +{ + float f11 = 3.3E-10000000000000000000f; /* { dg-warning "floating constant truncated to zero" } */ + float f22 = -3.3E-10000000000000000000f; /* { dg-warning "floating constant truncated to zero" } */ + float f1 = 3.3E-46f; /* { dg-warning "floating constant truncated to zero" } */ + float f2 = -3.3E-46f; /* { dg-warning "floating constant truncated to zero" } */ + float f3 = 0; + float f4 = -0; + float f5 = 0.0; + float f6 = -0.0; + + double d11 = 3.3E-10000000000000000000; /* { dg-warning "floating constant truncated to zero" } */ + double d22 = -3.3E-10000000000000000000; /* { dg-warning "floating constant truncated to zero" } */ + double d1 = 1.4E-325; /* { dg-warning "floating constant truncated to zero" } */ + double d2 = -1.4E-325; /* { dg-warning "floating constant truncated to zero" } */ + double d3 = 0; + double d4 = -0; + double d5 = 0.0; + double d6 = -0.0; +} -- cgit v1.2.3
