* Implement the missing pieces needed to support libstdc++4.7's <atomic>:Richard Smith2012-04-132-13/+127
| | | | | | | | | | | | | | | | | | | | | | | | | __atomic_test_and_set, __atomic_clear, plus a pile of undocumented __GCC_* predefined macros. Implement library fallback for __atomic_is_lock_free and __c11_atomic_is_lock_free, and implement __atomic_always_lock_free. Contrary to their documentation, GCC's __atomic_fetch_add family don't multiply the operand by sizeof(T) when operating on a pointer type. libstdc++ relies on this quirk. Remove this handling for all but the __c11_atomic_fetch_add and __c11_atomic_fetch_sub builtins. Contrary to their documentation, __atomic_test_and_set and __atomic_clear take a first argument of type 'volatile void *', not 'void *' or 'bool *', and __atomic_is_lock_free and __atomic_always_lock_free have an argument of type 'const volatile void *', not 'void *'. With this change, libstdc++4.7's <atomic> passes libc++'s atomic test suite, except for a couple of libstdc++ bugs and some cases where libc++'s test suite tests for properties which implementations have latitude to vary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154640 91177308-0d34-0410-b5e6-96231b3b80d8
* Warn on 64-to-32 for source value of x bits where 64 >= x > 32.David Blaikie2012-04-121-0/+4
| | | | | | | | | The codepath already only works for source bits > target bits, it's just that it was testing for the source expr bits to be exactly 64. This meant simple cases (int i = x_long / 2) were missed & ended up under the general -Wconversion warning, which a user might not have enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154626 91177308-0d34-0410-b5e6-96231b3b80d8
* [analyzer] PCH deserialization optimization.Anna Zaks2012-04-122-0/+37
| | | | | | | | | | | | | | | | We should not deserialize unused declarations from the PCH file. Achieve this by storing the top level declarations during parsing (HandleTopLevelDecl ASTConsumer callback) and analyzing/building a call graph only for those. Tested the patch on a sample ObjC file that uses PCH. With the patch, the analyzes is 17.5% faster and clang consumes 40% less memory. Got about 10% overall build/analyzes time decrease on a large Objective C project. A bit of CallGraph refactoring/cleanup as well.. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154625 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix some i1/i8 confusion within _Atomic(bool) in IR generation, bothDouglas Gregor2012-04-121-1/+24
| | | | | | | | | | | | | | | | in general (such an atomic has boolean representation) and specifically for IR generation of __c11_atomic_init. The latter also means actually using initialization semantics for this initialization, rather than just creating a store. On a related note, make sure we actually put in non-atomic-to-atomic conversions when performing an implicit conversion sequence. IR generation is far too kind here, but we still want the ASTs to make sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154612 91177308-0d34-0410-b5e6-96231b3b80d8

* Compute standard conversion sequences for conversions to atomicDouglas Gregor2012-04-121-0/+23
| | | | | | | | | | | | | types. The second and third conversions in the sequence are based on the conversion for the underlying type, so that we get sensible overloading behavior for, e.g., _Atomic(int) vs. _Atomic(float). As part of this, actually implement the lvalue-to-rvalue conversion for atomic types. There is probably a pile of code in SemaExpr that can now be deleted, but I haven't tracked it down yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154596 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement support for 18 of the GNU-compatible __atomic builtins.Richard Smith2012-04-124-32/+202
| | | | | | | | | | | | | This is not quite sufficient for libstdc++'s <atomic>: we still need __atomic_test_and_set and __atomic_clear, and may need a more complete __atomic_is_lock_free implementation. We are also missing an implementation of __atomic_always_lock_free, __atomic_nand_fetch, and __atomic_fetch_nand, but those aren't needed for libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154579 91177308-0d34-0410-b5e6-96231b3b80d8
