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/Wswitch-2.C | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/Wswitch-2.C (limited to 'gcc/testsuite/g++.dg/warn/Wswitch-2.C') diff --git a/gcc/testsuite/g++.dg/warn/Wswitch-2.C b/gcc/testsuite/g++.dg/warn/Wswitch-2.C new file mode 100644 index 000000000..79ba4bdcb --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/Wswitch-2.C @@ -0,0 +1,31 @@ +/* Further -Wswitch tests. */ +/* { dg-do compile } */ +/* { dg-options "-Wswitch" } */ + +enum e { e1 = 0, e2 = 1, e3 = 1, e4 = 2 }; + +int +foo (enum e ei, int j) +{ + switch (ei) + { + case e1: return 1; + case e3: return 2; + case e4: return 3; + } /* No warning here since e2 has the same value as e3. */ + switch (ei) /* { dg-warning "enumeration value 'e4' not handled in switch" "enum e4" } */ + { + case e1: return 1; + case e2: return 2; + } + switch ((int) ei) + { + case e1: return 1; + } /* No warning here since switch condition was cast to int. */ + switch ((enum e) j) /* { dg-warning "enumeration value 'e1' not handled in switch" "enum e1" } */ + { + case e2: return 1; + case e4: return 2; + } + return 0; +} -- cgit v1.2.3
