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/Wunused-var-7.c | 48 ++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/Wunused-var-7.c (limited to 'gcc/testsuite/c-c++-common/Wunused-var-7.c') diff --git a/gcc/testsuite/c-c++-common/Wunused-var-7.c b/gcc/testsuite/c-c++-common/Wunused-var-7.c new file mode 100644 index 000000000..74196436d --- /dev/null +++ b/gcc/testsuite/c-c++-common/Wunused-var-7.c @@ -0,0 +1,48 @@ +/* PR c++/44062 */ +/* { dg-do compile } */ +/* { dg-options "-Wunused" } */ + +void +foo (void) +{ + int a, b, c, d, e, f, g; + a = 1; + b = 2; + c = 3; + d = 4; + e = 5; + f = 6; + g = 7; + a; /* { dg-warning "no effect" } */ + b, 1; /* { dg-warning "no effect" } */ + (void) c; + (void) d, 1; /* { dg-warning "no effect" } */ + e, f, 1; /* { dg-warning "no effect" } */ + (void) g, f, 1; /* { dg-warning "no effect" } */ +} + +void +bar (void) +{ + int a; + int b; + int c; /* { dg-warning "set but not used" } */ + a = 1; + b = 2; + c = 3; + c = ({ a++, b; }); +} + +void +baz (void) +{ + int a; + int b; + int c; + int d; + a = 1; + b = 2; + c = 3; + d = 4; + d, ( a++, b ), c; /* { dg-warning "no effect" } */ +} -- cgit v1.2.3
