552c6c23 - PR44406: Follow behavior of array bound constant folding in more recent versions of GCC.

Fri, 16 Oct 2020 02:32:15 +0000

PR44406: Follow behavior of array bound constant folding in more recent versions of GCC.Old GCC used to aggressively fold VLAs to constant-bound arrays at blockscope in GNU mode. That's non-conforming, and more modern versions ofGCC only do this at file scope. Update Clang to do the same.Also promote the warning for this from off-by-default to on-by-defaultin all cases; more recent versions of GCC likewise warn on this bydefault.This is still slightly more permissive than GCC, as pointed out inPR44406, as we still fold VLAs to constant arrays in structs, but thatseems justifiable given that we don't support VLA-in-struct (and don'tintend to ever support it), but GCC does.Differential Revision: https://reviews.llvm.org/D89523 List of files: /llvm-project-15.0.7/clang/test/Sema/typedef-variable-type.c

when compiling in a GNU mode (e.g. gnu99) treat VLAs with a size that can be folded to a constantas constant size arrays. This has slightly different semantics in some insane cases, but allowsus to accept some constructs that GCC does. Continue to be pedantic in -std=c99 and othermodes.

8fbe78f6 - Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.

Tue, 15 Dec 2009 20:14:24 +0000

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/Sema/typedef-variable-type.c
