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/local1.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/local1.c (limited to 'gcc/testsuite/gcc.dg/local1.c') diff --git a/gcc/testsuite/gcc.dg/local1.c b/gcc/testsuite/gcc.dg/local1.c new file mode 100644 index 000000000..e9f653bcc --- /dev/null +++ b/gcc/testsuite/gcc.dg/local1.c @@ -0,0 +1,23 @@ +/* This is allowed, with the effect that the 'extern' declaration at block + scope refers to the same object as the 'static' declaration at file scope. + + C90 6.1.2.2 [as corrected by TC1], C99 6.2.2: + + For an identifier declared with the storage-class specifier + extern in a scope in which a prior declaration of that + identifier is visible, if the prior declaration specifies + internal or external linkage, the linkage of the identifier at + the later daclaration is the same as the linkage specified at + the prior declaration.
