2013-04-10MC: Support COFF image-relative MCSymbolRefsNico Rieck
Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are similar to normal 4-byte relocations except that they do not include the base address of the image. Image-relative relocations are used for debug information (32-bit) and SEH unwind tables (64-bit). A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to specify such relocations. For AT&T assembly, this variant can be accessed using the symbol suffix '@imgrel'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179240 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Manually remove successors in if conversion when CopyAndPredicateBlock is usedHal Finkel
In the simple and triangle if-conversion cases, when CopyAndPredicateBlock is used because the to-be-predicated block has other predecessors, we need to explicitly remove the old copied block from the successors list. Normally if conversion relies on TII->AnalyzeBranch combined with BB->CorrectExtraCFGEdges to cleanup the successors list, but if the predicated block contained an un-analyzable branch (such as a now-predicated return), then this will fail. These extra successors were causing a problem on PPC because it was causing later passes (such as PPCEarlyReturm) to leave dead return-only basic blocks in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179227 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10PPC: Don't predicate a diamond with two counter decrementsHal Finkel
I've not seen this happen in practice, and probably can't until we start allowing decrement-counter-based conditional branches to be double predicated, but just in case, don't allow predication of a diamond in which both sides have ctr-defining branches. Even though the branching behavior of these can be predicated, the counter-decrementing behavior cannot be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179199 91177308-0d34-0410-b5e6-96231b3b80d8

Original commit message below: [ms-inline asm] Use parsePrimaryExpr in lieu of parseExpression if we need to parse an identifier. Otherwise, parseExpression may parse multiple tokens, which makes it impossible to properly compute an immediate displacement.

2013-04-10This is for an experimental option -mips-os16. The idea is to compile allReed Kotler
Mips32 code as Mips16 unless it can't be compiled as Mips 16. For now this would happen as long as floating point instructions are not needed. Probably it would also make sense to compile as mips32 if atomic operations are needed too. There may be other cases too. A module pass prescans the IR and adds the mips16 or nomips16 attribute to functions depending on the functions needs. Mips 16 mode can result in a 40% code compression by utililizing 16 bit encoding of many instructions. The hope is for this to replace the traditional gcc way of dealing with Mips16 code using floating point which involves essentially using soft float but with a library implemented using mips32 floating point. This gcc method also requires creating stubs so that Mips32 code can interact with these Mips 16 functions that have floating point needs. My conjecture is that in reality this traditional gcc method would never win over this new method. I will be implementing the traditional gcc method also. Some of it is already done but I needed to do the stubs to finish the work and those required this mips16/32 mixed mode capability. I have more ideas for to make this new method much better and I think the old method will just live in llvm for anyone that needs the backward compatibility but I don't for what reason that would be needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179185 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10[test] Use lit's shell test runner on WindowsReid Kleckner
Summary: I did a local comparison between using bash and using lit's runner, and more of the suite passes with lit than passes with bash. Most of the bash failures have to do with /dev/null, which is nonsensical on Windows, but the lit runner handles it. The lit shell runner is also much faster than bash, so I would expect most Windows devs would want it by default. The behavior can be overridden on any OS by setting LIT_USE_INTERNAL_SHELL to 0 or 1 in the environment.

These instructions aren't universally available, but depend on a specific extension to the normal ARM architecture (rather than, say, v6/v7/...) so a new feature is appropriate.

2013-04-10PPC: Prep for if conversion of bctr[l]Hal Finkel
This adds in-principle support for if-converting the bctr[l] instructions. These instructions are used for indirect branching. It seems, however, that the current if converter will never actually predicate these. To do so, it would need the ability to hoist a few setup insts. out of the conditionally-executed block. For example, code like this: void foo(int a, int (*bar)()) { if (a != 0) bar(); } becomes: ... beq 0, .LBB0_2 std 2, 40(1) mr 12, 4 ld 3, 0(4) ld 11, 16(4) ld 2, 8(4) mtctr 3 bctrl ld 2, 40(1) .LBB0_2: ... and it would be safe to do all of this unconditionally with a predicated beqctrl instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179156 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09Allow PPC B and BLR to be if-converted into some predicated formsHal Finkel
This enables us to form predicated branches (which are the same conditional branches we had before) and also a larger set of predicated returns (including instructions like bdnzlr which is a conditional return and loop-counter decrement all in one). At the moment, if conversion does not capture all possible opportunities. A simple example is provided in early-ret2.ll, where if conversion forms one predicated return, and then the PPCEarlyReturn pass picks up the other one. So, at least for now, we'll keep both mechanisms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179134 91177308-0d34-0410-b5e6-96231b3b80d8
