2014-02-24Introduce the asmjs-unknown-emscripten target triple.Dan Gohman
Notable changes from le32-unknown-nacl so far include: - Set i32 as the legal integer set, to help the optimizer avoid creating needlessly inefficient code for asm.js. - We can use llvm.pow. - Don't predefine __ELF__ or __pnacl__ so that we don't need to undefine them later. - Do predefine asm.js and Emscripten macros, so that we don't need to define them later. - Don't provide __has_feature(pnacl).
2013-08-07Treat __sync_synchronize and asm("":::"memory") as stronger fences.JF Bastien
This is a companion patch to: https://codereview.chromium.org/22240002/ https://codereview.chromium.org/22474008/ and deals with the Clang-side of things. The above patch will handle the fallouts of this Clang patch, including some changes to un-duplicate work that RewriteAsmDirectives.cpp does. The goal of this patch is to force some extra ordering on non-atomics for le32 which LLVM doesn't necessarily provide.

2013-07-10Cherry-picking the pow-for-le32 fix from upstream clang.Eli Bendersky
SVN log from upstream clang: r185568 | eliben | 2013-07-03 12:19:12 -0700 (Wed, 03 Jul 2013) Add target hook CodeGen queries when generating builtin pow*. Without fmath-errno, Clang currently generates calls to @llvm.pow.* intrinsics when it sees pow*(). This may not be suitable for all targets (for example le32/PNaCl), so the attached patch adds a target hook that CodeGen queries. The target can state its preference for having or not having the intrinsic generated. Non-PNaCl behavior remains unchanged; PNaCl-specific test added.

2013-06-27Clang should not generate calls to llvm.pow.* intrinsics.Eli Bendersky
Instead, it should generate calls to the pow* library functions, which get found within the pexe. This is a LOCALMOD for now, but I'm working on a more generic solution that can be upstreamed to Clang.

------------------------------------------------------------------------ r182266 | rnk | 2013-05-20 07:02:37 -0700 (Mon, 20 May 2013) | 13 lines Implement __declspec(selectany) under -fms-extensions selectany only applies to externally visible global variables. It has the effect of making the data weak_odr. The MSDN docs suggest that unused definitions can only be dropped at linktime, so Clang uses weak instead of linkonce. MSVC optimizes away references to constant selectany data, so it must assume that there is only one definition, hence weak_odr.

2013-05-06Add SystemZ supportUlrich Weigand
This patch then adds all the usual platform-specific pieces for SystemZ: driver support, basic target info, register names and constraints, ABI info and vararg support. It also adds new tests to verify pre-defined macros and inline asm, and updates a test for the minimum alignment change. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers!

2013-05-03Reapply r180982 with repaired logic and an additional testcase.Adrian Prantl
Un-break the gdb buildbot. - Use the debug location of the return expression for the cleanup code if the return expression is trivially evaluatable, regardless of the number of stop points in the function. - Ensure that any EH code in the cleanup still gets the line number of the closing } of the lexical scope. - Added a testcase with EH in the cleanup. rdar://problem/13442648 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181056 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-03Move parsing of identifiers in MS-style inline assembly intoJohn McCall
the actual parser and support arbitrary id-expressions. We're actually basically set up to do arbitrary expressions here if we wanted to. Assembly operands permit things like A::x to be written regardless of language mode, which forces us to embellish the evaluation context logic somewhat. The logic here under template instantiation is incorrect; we need to preserve the fact that an expression was unevaluated. Of course, template instantiation in general is fishy here because we have no way of delaying semantic analysis in the MC parser. It's all just fishy. I've also fixed the serialization of MS asm statements. This commit depends on an LLVM commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180976 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Struct-path aware TBAA: uniformize scalar tag and path tag.Manman Ren
For struct-path aware TBAA, we used to use scalar type node as the scalar tag, which has an incompatible format with the struct path tag. We now use the same format: base type, access type and offset. We also uniformize the scalar type node and the struct type node: name, a list of pairs (offset + pointer to MDNode). For scalar type, we have a single pair. These are to make implementaiton of aliasing rules easier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179335 91177308-0d34-0410-b5e6-96231b3b80d8
