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/g++.dg/warn/pr33738.C | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/pr33738.C (limited to 'gcc/testsuite/g++.dg/warn/pr33738.C') diff --git a/gcc/testsuite/g++.dg/warn/pr33738.C b/gcc/testsuite/g++.dg/warn/pr33738.C new file mode 100644 index 000000000..e84fece13 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/pr33738.C @@ -0,0 +1,26 @@ +// { dg-do run } +// { dg-options "-O2 -Wtype-limits -fstrict-enums" } +extern void link_error (void); + +enum Alpha { + ZERO = 0, ONE, TWO, THREE +}; + +Alpha a2; + +int m1 = -1; +int GetM1() { + return m1; +} + +int main() { + a2 = static_cast(GetM1()); + if (a2 == -1) { // { dg-warning "always false due" } + link_error (); + } + if (-1 == a2) { // { dg-warning "always false due" } + link_error (); + } + return 0; +} + -- cgit v1.2.3
