* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - 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

* Implement the conditional-operator part of -Wsign-compare. TurnJohn McCall2009-11-051-0/+19
| | | | | | | | | | | | DiagnoseSignCompare into Sema::CheckSignCompare and call it from more places. Add some enumerator tests. These seem to expose some oddities in the types we're converting C++ enumerators to; in particular, they're converting to unsigned before int, which seems to contradict 4.5 [conv.prom] p2. Note to self: stop baiting Doug in my commit messages. llvm-svn: 86128

* Change Sema::CheckAddressOfOperation() to respect C99-only addressof rules.Steve Naroff2008-01-131-1/+1
| | | | | | | | | | | | | | | | | | Remove diagnostics from Sema::CheckIndirectionOperand(). C89/C99 allow dereferencing an incomplete type. clang appears to be emulating some incorrect gcc behavior (see below). void foo (void) { struct b; struct b* x = 0; struct b* y = &*x; // gcc produces an error ("dereferencing pointer to incomplete type") } With this patch, the above is now allowed. Bug/Patch by Eli Friedman! llvm-svn: 45933
