PR9792: Make sure to use the right definition of wchar_t when the default wchar_t is an unsigned type. llvm-svn: 130620
2011-05-01 03:24:24 +08:00
// RUN: %clang_cc1 -triple i386-mingw32 -fsyntax-only -pedantic -verify %s
Driver: hoist the `wchar_t` handling to the driver Move the logic for determining the `wchar_t` type information into the driver. Rather than passing the single bit of information of `-fshort-wchar` indicate to the frontend the desired type of `wchar_t` through a new `-cc1` option of `-fwchar-type` and indicate the signedness through `-f{,no-}signed-wchar`. This replicates the current logic which was spread throughout Basic into the `RenderCharacterOptions`. Most of the changes to the tests are to ensure that the frontend uses the correct type. Add a new test set under `test/Driver/wchar_t.c` to ensure that we calculate the proper types for the various cases. llvm-svn: 315126

Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280

// Check that short wchar_t is unsigned, and that regular wchar_t is not.
int test[(wchar_t(-1)<wchar_t(0)) == (sizeof(wchar_t) == 4) ?1:-1];
