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/gcc.dg/c90-array-lval-1.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c90-array-lval-1.c (limited to 'gcc/testsuite/gcc.dg/c90-array-lval-1.c') diff --git a/gcc/testsuite/gcc.dg/c90-array-lval-1.c b/gcc/testsuite/gcc.dg/c90-array-lval-1.c new file mode 100644 index 000000000..69655c835 --- /dev/null +++ b/gcc/testsuite/gcc.dg/c90-array-lval-1.c @@ -0,0 +1,21 @@ +/* Test for non-lvalue arrays decaying to pointers: in C99 only. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1990 -pedantic-errors" } */ + +struct s { char c[1]; }; + +extern struct s foo (void); + +void +bar (void) +{ + char *t; + (foo ()).c[0]; /* { dg-bogus "warning" "warning in place of error" } */ + t = (foo ()).c; /* { dg-bogus "warning" "warning in place of error" } */ + (foo ()).c + 1; /* { dg-bogus "warning" "warning in place of error" } */ +} +/* { dg-error "non-lvalue" "array not decaying to lvalue" { target *-*-* } 14 } + { dg-error "non-lvalue|incompatible" "array not decaying to lvalue" { target *-*-* } 15 } + { dg-error "non-lvalue|invalid" "array not decaying to lvalue" { target *-*-* } 16 } +*/ -- cgit v1.2.3
