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/c-c++-common/dfp/compare-rel-const.c | 57 ++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/compare-rel-const.c (limited to 'gcc/testsuite/c-c++-common/dfp/compare-rel-const.c') diff --git a/gcc/testsuite/c-c++-common/dfp/compare-rel-const.c b/gcc/testsuite/c-c++-common/dfp/compare-rel-const.c new file mode 100644 index 000000000..8e99b4466 --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/compare-rel-const.c @@ -0,0 +1,57 @@ +/* C99 6.5.8 Relational operators. + Compare decimal float constants against each other. */ + +extern void link_error (void); + +int +main () +{ + /* Compare like-typed negative constants. */ + if (-2.0dl < -2.0dl) + link_error (); + + /* Compare like-typed constants. */ + if (-2.0dl >= .01dl) + link_error (); + + /* Compare like-typed constants. */ + if (0.2dd > 0.02e1dd) + link_error (); + + /* Compare decimal float constants of different types. */ + if (-.000005dd >= -.0000049DL) + link_error(); + + /* Test use gcc builtins for comparisons. */ + if (__builtin_isless(-2.0dl,-2.0dl)) + link_error(); + + if (__builtin_isgreaterequal(-2.0dl,.01dl)) + link_error(); + + if (!(__builtin_islessequal(-2.0dl, -2.0dd))) + link_error(); + + if (!(__builtin_isgreater(2.0dl, -2.0dd))) + link_error(); + + if (__builtin_islessequal(2.0df, __builtin_nand64(""))) + link_error(); + + if (__builtin_islessgreater(2.0dd, __builtin_nand64(""))) + link_error(); + + if (!__builtin_islessgreater(2.0dd, -2.0dd)) + link_error(); + + if (!__builtin_islessgreater(-3.0dd, 2.0dd)) + link_error(); + + if (__builtin_isunordered(1.1df, 0.003dd)) + link_error(); + + if (!__builtin_isunordered(-3.1df, __builtin_nand32(""))) + link_error(); + + return 0; +} -- cgit v1.2.3
