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-compare-3.c | 159 ++++++++++++++++++++++++++++++++++ 1 file changed, 159 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/fold-compare-3.c (limited to 'gcc/testsuite/gcc.dg/fold-compare-3.c') diff --git a/gcc/testsuite/gcc.dg/fold-compare-3.c b/gcc/testsuite/gcc.dg/fold-compare-3.c new file mode 100644 index 000000000..d38a945ae --- /dev/null +++ b/gcc/testsuite/gcc.dg/fold-compare-3.c @@ -0,0 +1,159 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-cfg" } */ + +#include + +void this_comparison_is_false (void); +void this_comparison_is_true (void); +void this_comparison_is_not_decidable (void); + +void bla1eq (int var) +{ + if (var + 10 == INT_MIN + 9) + this_comparison_is_false (); +} + +void bla2eq (int var) +{ + if (var + 10 == INT_MIN + 10) + this_comparison_is_not_decidable (); +} + +void bla3eq (int var) +{ + if (var - 10 == INT_MAX - 9) + this_comparison_is_false (); +} + +void bla4eq (int var) +{ + if (var - 10 == INT_MAX - 10) + this_comparison_is_not_decidable (); +} + +void bla1ne (int var) +{ + if (var + 10 != INT_MIN + 9) + this_comparison_is_true (); +} + +void bla2ne (int var) +{ + if (var + 10 != INT_MIN + 10) + this_comparison_is_not_decidable (); +} + +void bla3ne (int var) +{ + if (var - 10 != INT_MAX - 9) + this_comparison_is_true (); +} + +void bla4ne (int var) +{ + if (var - 10 != INT_MAX - 10) + this_comparison_is_not_decidable (); +} + +void bla1lt (int var) +{ + if (var + 10 < INT_MIN + 10) + this_comparison_is_false (); +} + +void bla2lt (int var) +{ + if (var + 10 < INT_MIN + 11) + this_comparison_is_not_decidable (); +} + +void bla3lt (int var) +{ + if (var - 10 < INT_MAX - 9) + this_comparison_is_true (); +} + +void bla4lt (int var) +{ + if (var - 10 < INT_MAX - 10) + this_comparison_is_not_decidable (); +} + +void bla1le (int var) +{ + if (var + 10 <= INT_MIN + 9) + this_comparison_is_false (); +} + +void bla2le (int var) +{ + if (var + 10 <= INT_MIN + 10) + this_comparison_is_not_decidable (); +} + +void bla3le (int var) +{ + if (var - 10 <= INT_MAX - 10) + this_comparison_is_true (); +} + +void bla4le (int var) +{ + if (var - 10 <= INT_MAX - 11) + this_comparison_is_not_decidable (); +} + +void bla1gt (int var) +{ + if (var + 10 > INT_MIN + 9) + this_comparison_is_true (); +} + +void bla2gt (int var) +{ + if (var + 10 > INT_MIN + 10) + this_comparison_is_not_decidable (); +} + +void bla3gt (int var) +{ + if (var - 10 > INT_MAX - 10) + this_comparison_is_false (); +} + +void bla4gt (int var) +{ + if (var - 10 > INT_MAX - 11) + this_comparison_is_not_decidable (); +} + +void bla1ge (int var) +{ + if (var + 10 >= INT_MIN + 10) + this_comparison_is_true (); +} + +void bla2ge (int var) +{ + if (var + 10 >= INT_MIN + 11) + this_comparison_is_not_decidable (); +} + +void bla3ge (int var) +{ + if (var - 11 >= INT_MAX - 10) + this_comparison_is_false (); +} + +void bla4ge (int var) +{ + if (var - 10 >= INT_MAX - 10) + this_comparison_is_not_decidable (); +} + +/* { dg-final { scan-tree-dump-times "this_comparison_is_false" 0 "cfg" } } */ +/* { dg-final { scan-tree-dump-times "this_comparison_is_true" 6 "cfg" } } */ +/* { dg-final { scan-tree-dump-times "this_comparison_is_not_decidable" 12 "cfg" } } */ +/* { dg-final { scan-tree-dump-times "if " 12 "cfg" } } */ + +/* { dg-final { cleanup-tree-dump "cfg" } } */ -- cgit v1.2.3
