This also meant that the 'this' pointer of the functionparameter could be observed changing between the caller and the callee.This change completely reimplements how we model function parametersduring constant evaluation. We now model them roughly as if they werevariables living in the caller, albeit with an artificially reducedscope that covers only the duration of the function call, instead ofmodeling them as temporaries in the caller that we partially "reparent"into the callee at the point of the call. This brings some minordiagnostic improvements, as well as significantly reduced stack usageduring constant evaluation.

Currently Clangimplements -Wvla as "warn on VLA when it is an extension".The attached patch makes our behavior match GCC. The existing vla extwarn ismoved under -Wvla-extension and is still included into -Wgnu.This fixes PR5953.llvm-svn: 173286 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/warn-vla.cpp Wed, 23 Jan 2013 20:02:51 +0000 Dmitri Gribenko <gribozavr@gmail.com>
