Michael Kuperstein	9d0cf0b63f	HasSideEffects() should return false for calls to pure and const functions. Differential Revision: http://reviews.llvm.org/D8548 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@234152 91177308-0d34-0410-b5e6-96231b3b80d8	2015-04-06 13:22:01 +00:00
David Blaikie	1d7abba8db	Update Clang tests to handle explicitly typed load changes in LLVM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@230795 91177308-0d34-0410-b5e6-96231b3b80d8	2015-02-27 21:19:58 +00:00
NAKAMURA Takumi	0e59cbece8	clang/test/CodeGen/builtin-assume*.c: Fixup for -Asserts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@217352 91177308-0d34-0410-b5e6-96231b3b80d8	2014-09-08 01:12:55 +00:00
Hal Finkel	687b32ee47	Add __builtin_assume and __builtin_assume_aligned using @llvm.assume. This makes use of the recently-added @llvm.assume intrinsic to implement a __builtin_assume(bool) intrinsic (to provide additional information to the optimizer). This hooks up __assume in MS-compatibility mode to mirror __builtin_assume (the semantics have been intentionally kept compatible), and implements GCC's __builtin_assume_aligned as assume((p - o) & mask == 0). LLVM now contains special logic to deal with assumptions of this form. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@217349 91177308-0d34-0410-b5e6-96231b3b80d8	2014-09-07 22:58:14 +00:00
Hal Finkel	e85f0ef7d5	Add basic (noop) CodeGen support for __assume Clang supports __assume, at least at the semantic level, when MS extensions are enabled. Unfortunately, trying to actually compile code using __assume would result in this error: error: cannot compile this builtin function yet __assume is an optimizer hint, and can be ignored at the IR level. Until LLVM supports assumptions at the IR level, a noop lowering is valid, and that is what is done here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@213206 91177308-0d34-0410-b5e6-96231b3b80d8	2014-07-16 22:44:54 +00:00
