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/torture/builtin-rounding-1.c | 120 ++++++++++++++++++++++ 1 file changed, 120 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/builtin-rounding-1.c (limited to 'gcc/testsuite/gcc.dg/torture/builtin-rounding-1.c') diff --git a/gcc/testsuite/gcc.dg/torture/builtin-rounding-1.c b/gcc/testsuite/gcc.dg/torture/builtin-rounding-1.c new file mode 100644 index 000000000..816cffc04 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/builtin-rounding-1.c @@ -0,0 +1,120 @@ +/* Copyright (C) 2004 Free Software Foundation. + + Check that constant folding of the rounding math functions doesn't + break anything and produces the expected results. + + Written by Kaveh Ghazi, 2004-04-29. */ + +/* { dg-do link } */ + +extern int link_error (int); + +#define TEST(FN, VALUE, RESULT) \ + if (__builtin_##FN (VALUE) != RESULT) link_error (__LINE__); \ + if (__builtin_##FN##f (VALUE) != RESULT) link_error (__LINE__); \ + if (__builtin_##FN##l (VALUE) != RESULT) link_error (__LINE__); \ + +int +main (void) +{ + TEST(trunc, 0, 0); + TEST(floor, 0, 0); + TEST(ceil, 0, 0); + TEST(round, 0, 0); + TEST(lround, 0, 0); + TEST(llround, 0, 0); + TEST(lfloor, 0, 0); + TEST(llfloor, 0, 0); + TEST(lceil, 0, 0); + TEST(llceil, 0, 0); + + TEST(trunc, 6, 6); + TEST(floor, 6, 6); + TEST(ceil, 6, 6); + TEST(round, 6, 6); + TEST(lround, 6, 6); + TEST(llround, 6, 6); + TEST(lfloor, 6, 6); + TEST(llfloor, 6, 6); + TEST(lceil, 6, 6); + TEST(llceil, 6, 6); + + TEST(trunc, -8, -8); + TEST(floor, -8, -8); + TEST(ceil, -8, -8); + TEST(round, -8, -8); + TEST(lround, -8, -8); + TEST(llround, -8, -8); + TEST(lfloor, -8, -8); + TEST(llfloor, -8, -8); + TEST(lceil, -8, -8); + TEST(llceil, -8, -8); + + TEST(trunc, 3.2, 3); + TEST(floor, 3.2, 3); + TEST(ceil, 3.2, 4); + TEST(round, 3.2, 3); + TEST(lround, 3.2, 3); + TEST(llround, 3.2, 3); + TEST(lfloor, 3.2, 3); + TEST(llfloor, 3.2, 3); + TEST(lceil, 3.2, 4); + TEST(llceil, 3.2, 4); + + TEST(trunc, -2.8, -2); + TEST(floor, -2.8, -3); + TEST(ceil, -2.8, -2); + TEST(round, -2.8, -3); + TEST(lround, -2.8, -3); + TEST(llround, -2.8, -3); + TEST(lfloor, -2.8, -3); + TEST(llfloor, -2.8, -3); + TEST(lceil, -2.8, -2); + TEST(llceil, -2.8, -2); + + TEST(trunc, 0.01, 0); + TEST(floor, 0.01, 0); + TEST(ceil, 0.01, 1); + TEST(round, 0.01, 0); + TEST(lround, 0.01, 0); + TEST(llround, 0.01, 0); + TEST(lfloor, 0.01, 0); + TEST(llfloor, 0.01, 0); + TEST(lceil, 0.01, 1); + TEST(llceil, 0.01, 1); + + TEST(trunc, -0.7, 0); + TEST(floor, -0.7, -1); + TEST(ceil, -0.7, 0); + TEST(round, -0.7, -1); + TEST(lround, -0.7, -1); + TEST(llround, -0.7, -1); + TEST(lfloor, -0.7, -1); + TEST(llfloor, -0.7, -1); + TEST(lceil, -0.7, 0); + TEST(llceil, -0.7, 0); + + TEST(trunc, 2.5, 2); + TEST(floor, 2.5, 2); + TEST(ceil, 2.5, 3); + TEST(round, 2.5, 3); + TEST(lround, 2.5, 3); + TEST(llround, 2.5, 3); + TEST(lfloor, 2.5, 2); + TEST(llfloor, 2.5, 2); + TEST(lceil, 2.5, 3); + TEST(llceil, 2.5, 3); + + TEST(trunc, -1.5, -1); + TEST(floor, -1.5, -2); + TEST(ceil, -1.5, -1); + TEST(round, -1.5, -2); + TEST(lround, -1.5, -2); + TEST(llround, -1.5, -2); + TEST(lfloor, -1.5, -2); + TEST(llfloor, -1.5, -2); + TEST(lceil, -1.5, -1); + TEST(llceil, -1.5, -1); + + return 0; +} -- cgit v1.2.3
