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/fold-convround-1.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/fold-convround-1.c (limited to 'gcc/testsuite/gcc.dg/fold-convround-1.c') diff --git a/gcc/testsuite/gcc.dg/fold-convround-1.c b/gcc/testsuite/gcc.dg/fold-convround-1.c new file mode 100644 index 000000000..86612aa81 --- /dev/null +++ b/gcc/testsuite/gcc.dg/fold-convround-1.c @@ -0,0 +1,30 @@ +/* PR middle-end/28473. */ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-original" } */ + +extern double round(double); +extern double floor(double); +extern double ceil(double); + +unsigned long long test1(double x) +{ + return (unsigned long long) round(x); +} + +unsigned long long test2(double x) +{ + return (unsigned long long) floor(x); +} +unsigned long long test3(double x) +{ + return (unsigned long long) ceil(x); +} + +/* { dg-final { scan-tree-dump-times "__builtin_lround" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "__builtin_llround" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "__builtin_lfloor" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "__builtin_llfloor" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "__builtin_lceil" 0 "original" } } */ +/* { dg-final { scan-tree-dump-times "__builtin_llceil" 0 "original" } } */ +/* { dg-final { cleanup-tree-dump "original" } } */ + -- cgit v1.2.3
