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/Wunsuffixed-float-constants-1.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wunsuffixed-float-constants-1.c (limited to 'gcc/testsuite/gcc.dg/Wunsuffixed-float-constants-1.c') diff --git a/gcc/testsuite/gcc.dg/Wunsuffixed-float-constants-1.c b/gcc/testsuite/gcc.dg/Wunsuffixed-float-constants-1.c new file mode 100644 index 000000000..b4a38d5cb --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wunsuffixed-float-constants-1.c @@ -0,0 +1,17 @@ +/* { dg-do compile } */ +/* { dg-options "-std=gnu99 -Wunsuffixed-float-constants" } */ + +#define VAL 0.5; + +double a = 1.1d; + +/* With FLOAT_CONST_DECIMAL64 switched to ON these would have type + _Decimal64. */ + +double b = VAL; /* { dg-warning "unsuffixed float constant" } */ +double c = 1.2; /* { dg-warning "unsuffixed float constant" } */ + +/* With FLOAT_CONST_DECIMAL64 switched to ON these are still binary. */ + +double d = 0x5.0p1; /* No warning for hex constant. */ +double e = 3.1i; /* No warning for imaginary constant. */ -- cgit v1.2.3
