2012-05-04This patch adds a new Clang compiler flag "-gline-tables-only".Alexey Samsonov
It reduces the amount of emitted debug information: 1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram, DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only. 2) .debug_str contains only function names. 3) No debug data for types/namespaces/variables is emitted. 4) The data in .debug_line is enough to produce valid stack traces with function names and line numbers.

2012-04-28Currently __builtin_annotation() only annotates an i32.Julien Lerouge
i32 __builtin_annotation(i32, string); Applying it to i64 (e.g., long long) generates the following IR. trunc i64 {{.*}} to i32 call i32 @llvm.annotation.i32 zext i32 {{.*}} to i64 The redundant truncation and extension make the result difficult to use. This patch makes __builtin_annotation() generic. type __builtin_annotation(type, string); For the i64 example, it simplifies the generated IR to: call i64 @llvm.annotation.i64 Patch by Xi Wang! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155764 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-13Implement the missing pieces needed to support libstdc++4.7's <atomic>:Richard Smith
__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
2012-04-12Implement support for 18 of the GNU-compatible __atomic builtins.Richard Smith
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

2012-03-30The UTF16 string referenced by a CFString should go into the __TEXT,__ustringBill Wendling
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
