* Demote EmitRawText call in AsmPrinter::EmitInlineAsm() and remove ↵Daniel Sanders2014-02-12
| | | | | | | | | | | | | | | | | | | | | hasRawTextSupport() call Summary: AsmPrinter::EmitInlineAsm() will no longer use the EmitRawText() call for targets with mature MC support. Such targets will always parse the inline assembly (even when emitting assembly). Targets without mature MC support continue to use EmitRawText() for assembly output. The hasRawTextSupport() check in AsmPrinter::EmitInlineAsm() has been replaced with MCAsmInfo::UseIntegratedAs which when true, causes the integrated assembler to parse inline assembly (even when emitting assembly output). UseIntegratedAs is set to true for targets that consider any failure to parse valid assembly to be a bug. Target specific subclasses generally enable the integrated assembler in their constructor. The default value can be overridden with -no-integrated-as. All tests that rely on inline assembly supporting invalid assembly (for example, those that use mnemonics such as 'foo' or 'hello world') have been updated to disable the integrated assembler.

* Windows/Path.inc: Move <shlobj.h> after "Windows.h" for some API available.NAKAMURA Takumi2014-02-12
| | | | | | | | | | | | | | | I found that swapping the order of some header files helped fix a build issue that we're seeing on mingw32. Without the swap, windows.h was being included before _WIN32_WINNT was being defined and the CreateHardLinkW function was #ifdef'd out. It looks like the header is mainly used to get the SHGetFolderPathW function, so I don't think that there'll be much fallout from the switch. Suggested by Alex Crichton. Thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201230 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach tablegen() macro to check needed variablesNAKAMURA Takumi2014-02-12

* Tweak ARM fastcc by adopting these two AAPCS rules:Evan Cheng2014-02-11
| | | | | | | | | | | | | | | * CPRCs may be allocated to co-processor registers or the stack – they may never be allocated to core registers * When a CPRC is allocated to the stack, all other VFP registers should be marked as unavailable The difference is only noticeable in rare cases where there are a large number of floating point arguments (e.g. 7 doubles + additional float, double arguments). Although it's probably still better to avoid vmov as it can cause stalls in some older ARM cores. The other, more subtle benefit, is to minimize difference between the various calling conventions. rdar://16039676 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201193 91177308-0d34-0410-b5e6-96231b3b80d8

* [LPM] Switch LICM to actively use LCSSA in addition to preserving it.Chandler Carruth2014-02-11
| | | | | | | | | | | | | | | | | | | | | | | Fixes PR18753 and PR18782. This is necessary for LICM to preserve LCSSA correctly and efficiently. There is still some active discussion about whether we should be using LCSSA, but we can't just immediately stop using it and we *need* LICM to preserve it while we are using it. We can restore the old SSAUpdater driven code if and when there is a serious effort to remove the reliance on LCSSA from all of the loop passes. However, this also serves as a great example of why LCSSA is very nice to have. This change significantly simplifies the process of sinking instructions for LICM, and makes it quite a bit less expensive. It wouldn't even be as complex as it is except that I had to start the process of removing the big recursive LCSSA formation hammer in order to switch even this much of the re-forming code to asserting that LCSSA was preserved. I'll fully remove that next just to tidy things up until the LCSSA debate settles one way or the other. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201148 91177308-0d34-0410-b5e6-96231b3b80d8

* [CodeGenPrepare] Undo changes that happened for the profitability check.Quentin Colombet2014-02-11
| | | | | | | | | | | | | | | | | | The addressing mode matcher checks at some point the profitability of folding an instruction into the addressing mode. When the instruction to be folded has several uses, it checks that the instruction can be folded in each use. To do so, it creates a new matcher for each use and check if the instruction is in the list of the matched instructions of this new matcher. The new matchers may promote some instructions and this has to be undone to keep the state of the original matcher consistent. A test case will follow. <rdar://problem/16020230> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201121 91177308-0d34-0410-b5e6-96231b3b80d8
