* This reverts commit r200064 and r200051.Rafael Espindola2014-01-255-69/+42
| | | | | | | | | | | | | | | | | | | r200064 depends on r200051. r200051 is broken: I tries to replace .mips_hack_elf_flags, which is a good thing, but what it replaces it with is even worse. The new emitMipsELFFlags it adds corresponds to no assembly directive, is not marked as a hack and is not even printed to the .s file. The patch also introduces more uses of hasRawTextSupport. The correct way to remove .mips_hack_elf_flags is to have the mips target streamer handle the default flags (and command line options). That way the same code path is used for asm and obj. The streamer interface should *really* correspond to what is printed in the .s file. llvm-svn: 200078

* Revert "Add Constant Hoisting Pass" (r200034)Hans Wennborg2014-01-251-95/+0
| | | | | | | | | | | | | | | This commit caused -Woverloaded-virtual warnings. The two new TargetTransformInfo::getIntImmCost functions were only added to the superclass, and to the X86 subclass. The other targets were not updated, and the warning highlighted this by pointing out that e.g. ARMTTI::getIntImmCost was hiding the two new getIntImmCost variants. We could pacify the warning by adding "using TargetTransformInfo::getIntImmCost" to the various subclasses, or turning it off, but I suspect that it's wrong to leave the functions unimplemnted in those targets. The default implementations return TCC_Free, which I don't think is right e.g. for ARM. llvm-svn: 200058
* [Mips] TargetStreamer ELF flag Support for default and commandline options.Jack Carter2014-01-255-42/+69
| | | | | | | | | | | | | | | This patch uses a common MipsTargetSteamer interface for both MipsAsmPrinter and MipsAsmParser for recording default and commandline driven directives that affect ELF header flags. It has been noted that the .ll tests affected by this patch belong in test/Codegen/Mips. I will move them in a separate patch. Also, a number of directives do not get expressed by AsmPrinter in the resultant .s assembly such as setting the correct ASI. I have noted this in the tests and they will be addressed in later patches. llvm-svn: 200051
* [AArch64] Removed unused i8 type from FPR8 register class.Ana Pazos2014-01-241-1/+1
| | | | | | | | | | | | | | | The i8 type is not registered with any register class. This causes a segmentation fault in MachineLICM::getRegisterClassIDAndCost. The code selects the first type associated with register class FPR8, which happens to be i8. It uses this type (i8) to get the representative class pointer, which is 0. It then uses this pointer to access a field, resulting in segmentation fault. Since i8 type is not being used for printing any neon instruction we can safely remove it. llvm-svn: 200046
* Add Constant Hoisting PassJuergen Ributzka2014-01-241-0/+95
| | | | | | | | Retry commit r200022 with a fix for the build bot errors. Constant expressions have (unlike instructions) module scope use lists and therefore may have users in different functions. The fix is to simply ignore these out-of-function uses. llvm-svn: 200034

* Add Constant Hoisting PassJuergen Ributzka2014-01-241-0/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This pass identifies expensive constants to hoist and coalesces them to better prepare it for SelectionDAG-based code generation. This works around the limitations of the basic-block-at-a-time approach. First it scans all instructions for integer constants and calculates its cost. If the constant can be folded into the instruction (the cost is TCC_Free) or the cost is just a simple operation (TCC_BASIC), then we don't consider it expensive and leave it alone. This is the default behavior and the default implementation of getIntImmCost will always return TCC_Free. If the cost is more than TCC_BASIC, then the integer constant can't be folded into the instruction and it might be beneficial to hoist the constant. Similar constants are coalesced to reduce register pressure and materialization code. When a constant is hoisted, it is also hidden behind a bitcast to force it to be live-out of the basic block. Otherwise the constant would be just duplicated and each basic block would have its own copy in the SelectionDAG. The SelectionDAG recognizes such constants as opaque and doesn't perform certain transformations on them, which would create a new expensive constant. This optimization is only applied to integer constants in instructions and simple (this means not nested) constant cast experessions. For example: %0 = load i64* inttoptr (i64 big_constant to i64*) Reviewed by Eric llvm-svn: 200022

* Move emitInlineAsmEnd to the AsmPrinter interface.Rafael Espindola2014-01-243-17/+19
| | | | | | | | There is no inline asm in a .s file. Therefore, there should be no logic to handle it in the streamer. Inline asm only exists in bitcode files, so the logic can live in the (long misnamed) AsmPrinter class. llvm-svn: 200011

* [X86] Prevent the creation of redundant ops for sadd and ssub with overflow.Juergen Ributzka2014-01-241-2/+17
| | | | | | | | | | | | | This commit teaches the X86 backend to create the same X86 instructions when it lowers an sadd/ssub with overflow intrinsic and a conditional branch that uses that overflow result. This allows SelectionDAG to recognize and remove one of the redundant operations. This fixes <rdar://problem/15874016> and <rdar://problem/15661073>. Reviewed by Nadav llvm-svn: 199976

| | | | | | | | | | | | Implement the getUnrollingPreferences() function for AMDGPUTargetTransformInfo so that loops that do address calculations on pointers derived from alloca are unconditionally unrolled. Unrolling these loops makes it more likely that SROA will be able to eliminate the allocas, which is a big win for R600 since memory allocated by alloca (private memory) is really slow. llvm-svn: 199916
* R600: Recommit 199842: Add work-around for the CF stack entry HW bugTom Stellard2014-01-235-7/+63
| | | | | | | | | | | | | | | | | | The unit test is now disabled on non-asserts builds. The CF stack can be corrupted if you use CF_ALU_PUSH_BEFORE, CF_ALU_ELSE_AFTER, CF_ALU_BREAK, or CF_ALU_CONTINUE when the number of sub-entries on the stack is greater than or equal to the stack entry size and sub-entries modulo 4 is either 0 or 3 (on cedar the bug is present when number of sub-entries module 8 is either 7 or 0) We choose to be conservative and always apply the work-around when the number of sub-enries is greater than or equal to the stack entry size, so that we can safely over-allocate the stack when we are unsure of the stack allocation rules. reviewed-by: Vincent Lejeune <vljn at ovi.com> llvm-svn: 199905

| | | | | | | | | With constant-sharing, litpool loads consume 4 + N*2 bytes of code, but movw/movt pairs consume 8*N. This means litpools are better than movw/movt even with just one use. Other materialisation strategies can still be better though, so the logic is a little odd. llvm-svn: 199891
