* Implement the missing pieces needed to support libstdc++4.7's <atomic>:Richard Smith2012-04-131-5/+51
| | | | | | | | | | | | | | | | | | | | | | | | | __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
* Implement support for 18 of the GNU-compatible __atomic builtins.Richard Smith2012-04-122-23/+134
| | | | | | | | | | | | | 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

* The UTF16 string referenced by a CFString should go into the __TEXT,__ustringBill Wendling2012-03-302-2/+15
| | | | | | | | | | | | | | section. A 'normal' string will go into the __TEXT,__const section, but this isn't good for UTF16 strings. The __ustring section allows for coalescing, among other niceties (such as allowing the linker to easily split up strings). Instead of outputting the UTF16 string as a series of bytes, output it as a series of shorts. The back-end will then nicely place the UTF16 string into the correct section, because it's a mensch. <rdar://problem/10655949> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153710 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - We do this when it is easy to determine that the backend will pass them on the stack properly by itself. Currently LLVM codegen is really bad in some cases with byval, for example, on the test case here (which is derived from Sema code, which likes to pass SourceLocations around):: struct s47 { unsigned a; }; void f47(int,int,int,int,int,int,struct s47); void test47(int a, struct s47 b) { f47(a, a, a, a, a, a, b); } we used to emit code like this:: ... movl %esi, -8(%rbp) movl -8(%rbp), %ecx movl %ecx, (%rsp) ... to handle moving the struct onto the stack, which is just appalling. Now we generate:: movl %esi, (%rsp) which seems better, no? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152462 91177308-0d34-0410-b5e6-96231b3b80d8
