2013-01-31Improve 'failed template argument deduction' diagnostic for the case where weRichard Smith
have a direct mismatch between some component of the template and some component of the argument. The diagnostic now says what the mismatch was, but doesn't yet say which part of the template doesn't match. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174039 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Implement -Wvla correctlyDmitri Gribenko
GCC implements -Wvla as "warn on every VLA" (this is useful to find every VLA, for example, if they are forbidden by coding guidelines). Currently Clang implements -Wvla as "warn on VLA when it is an extension". The attached patch makes our behavior match GCC. The existing vla extwarn is moved under -Wvla-extension and is still included into -Wgnu. This fixes PR5953. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173286 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-29Change the diagnostics which said 'accepted as an extension' to instead sayRichard Smith
'is an extension'. The former is inappropriate and confusing when building with -Werror/-pedantic-errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147357 91177308-0d34-0410-b5e6-96231b3b80d8

folded to a constant as constant size arrays. This has slightly different semantics in some insane cases, but allows us to accept some constructs that GCC does. Continue to be pedantic in -std=c99 and other modes.

2010-10-06Reject the allocation of variably-modified types in C++ 'new'Douglas Gregor
expressions. Fixes PR8209 in the narrowest way possible. I'm still considering whether I want to implement the extension that permits the use of VLA types in a 'new' expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115790 91177308-0d34-0410-b5e6-96231b3b80d8

aren't dependent. Fixes <rdar://problem/8020206>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104511 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-23It turns out that people love using VLAs in templates, too. Weaken ourDouglas Gregor
VLA restrictions so that one can use VLAs in templates (even accidentally), but not as part of a non-type template parameter (which would be very bad). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104471 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-23Even though we don't unique VLA types, we still need to build aDouglas Gregor
canonical type where the element type is canonical. Fixes PR7206. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104461 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-22Implement support for variable length arrays in C++. VLAs are limitedDouglas Gregor
in several important ways: - VLAs of non-POD types are not permitted. - VLAs cannot be used in conjunction with C++ templates. These restrictions are intended to keep VLAs out of the parts of the C++ type system where they cause the most trouble. Fixes PR5678 and <rdar://problem/8013618>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104443 91177308-0d34-0410-b5e6-96231b3b80d8
