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/opt/enum1.C | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/enum1.C (limited to 'gcc/testsuite/g++.dg/opt/enum1.C') diff --git a/gcc/testsuite/g++.dg/opt/enum1.C b/gcc/testsuite/g++.dg/opt/enum1.C new file mode 100644 index 000000000..6416b3f1b --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/enum1.C @@ -0,0 +1,30 @@ +// Verify that we don't confuse precision and mode for enums. +// { dg-do run } +// { dg-options "-O" } + +extern "C" void abort(); + +enum E { + zero = 0, + test = 0xbb +}; + +static bool foo(unsigned char *x) +{ + E e = static_cast(*x); + switch (e) + { + case test: + return true; + default: + return false; + } +} + +int main() +{ + unsigned char dummy = test; + if (! foo(&dummy)) + abort (); + return 0; +} -- cgit v1.2.3
