2013-03-25Emit an error message instead of crashing when dereferencing an incomplete ↵Bill Wendling
pointer type. If the ASM statement is dereferencing an incomplete pointer type, issue an error instead of crashing. <rdar://problem/12700799> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177915 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-17c: privide deprecated warning when __private_extern__ storageFariborz Jahanian
specifier is unsed in a declaration; as it may not make the symbol local to linkage unit as intended. Suggest using "hidden" visibility attribute instead. // rdar://7703982 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162138 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-02Add support for AVX registers to clang inline asm. Add a small testcaseEric Christopher
and update the Sema testcase with a register that we won't hit for a while I hope. Fixes rdar://10510405 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145671 91177308-0d34-0410-b5e6-96231b3b80d8

constraint it's invalid. Fixes PR3905. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118146 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03A number in an input constraint can't point to a read-write ('+') ↵Anders Carlsson
constraint. Fixes PR3904. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118145 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-05make clang print types as "const int *" instead of "int const*",Chris Lattner
which is should have done from the beginning. As usual, the most fun with this sort of change is updating all the testcases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113090 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Warn on top-level 'asm volatile' (instead of misparsing it).John McCall
"Fixes" rdar://problem/7574870 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94458 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-19Remove the -arch option from clang-cc: for all practical purposes, it's Eli Friedman
