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-12.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/Wunused-var-12.c (limited to 'gcc/testsuite/c-c++-common/Wunused-var-12.c') diff --git a/gcc/testsuite/c-c++-common/Wunused-var-12.c b/gcc/testsuite/c-c++-common/Wunused-var-12.c new file mode 100644 index 000000000..94e56d8a8 --- /dev/null +++ b/gcc/testsuite/c-c++-common/Wunused-var-12.c @@ -0,0 +1,26 @@ +/* PR c++/44780 */ +/* { dg-do compile } */ +/* { dg-options "-Wunused" } */ +/* { dg-options "-Wunused -fno-common" { target { { hppa*-*-hpux* } && { ! hppa*64*-*-* } } } } */ + +typedef double vec __attribute__ ((__vector_size__ (16))); +vec c, d; + +void +foo (void) +{ + vec a; + vec b; + a = c; + b = a; + d = b; +} + +void +bar (void) +{ + vec a; + vec b; /* { dg-warning "set but not used" } */ + a = c; + b = a; +} -- cgit v1.2.3
