* cmake: Set LINK_POLLY_INTO_TOOLS to ON (v2)Tobias Grosser2016-04-292-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the second try. This time we disable this feature if no Polly checkout is available. For this to work we need to check if tools/polly is present early enough that our decision is known before cmake generates Config/config.h. With Polly checked into LLVM it was since a long time possible to compile clang/opt/bugpoint with Polly support directly linked in, instead of only providing Polly as a separate loadable module. This commit switches the default from providing Polly as a module to linking Polly into tools, such that it becomes unnecessary to load the Polly module when playing with Polly. Such configuration has shown a lot more convenient for day-to-day Polly use. This change does not impact the default behavior of any tool, if Polly is not explicitly enabled when calling clang/opt/bugpoint Polly does not affect compilation. This change also does not impact normal LLVM/clang checkouts that do not contain Polly.

* [mips][ias] Split expandMemInst between MipsAsmParser and ↵Daniel Sanders2016-04-295-68/+207
| | | | | | | | | | | | | | | | | | | | | | MipsTargetStreamer. Almost NFC. Summary: The portion in MipsAsmParser is responsible for figuring out which expansion to use, while the portion in MipsTargetStreamer is responsible for emitting it. This allows us to remove the call to isIntegratedAssemblerRequired() which is currently ensuring the effect of .cprestore only occurs when writing objects. The small functional change is that the memory offsets are now correctly printed as signed values.

* [mips][ias] Moved most instruction emission helpers to MipsTargetStreamer. NFC.Daniel Sanders2016-04-293-279/+325
| | | | | | | | | | | | | | | | | | | Summary: * Moved all the emit*() helpers to MipsTargetStreamer. * Moved createNop() to MipsTargetStreamer as emitNop() and emitEmptyDelaySlot(). This instruction has been split to distinguish between the 'nop' instruction and the nop used in delay slots which is sometimes a different nop to the 'nop' instruction (e.g. for short delay slots on microMIPS). * Moved createAddu() to MipsTargetStreamer as emitAddu(). * Moved createAppropriateDSLL() to MipsTargetStreamer as emitDSLL().

* AMDGPU/SI: Assembler: Unify parsing/printing of operands.Nikolay Haustov2016-04-2935-975/+717
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The goal is for each operand type to have its own parse function and at the same time share common code for tracking state as different instruction types share operand types (e.g. glc/glc_flat, etc). Introduce parseAMDGPUOperand which can parse any optional operand. DPP and Clamp/OMod have custom handling for now. Sam also suggested to have class hierarchy for operand types instead of table. This can be done in separate change. Remove parseVOP3OptionalOps, parseDS*OptionalOps, parseFlatOptionalOps, parseMubufOptionalOps, parseDPPOptionalOps. Reduce number of definitions of AsmOperand's and MatchClasses' by using common base class. Rename AsmMatcher/InstPrinter methods accordingly. Print immediate type when printing parsed immediate operand. Use 'off' if offset/index register is unused instead of skipping it to make it more readable (also agreed with SP3). Update tests.

* AMDGPU: Stop reporting an addressing mode for unknown addrspaceMatt Arsenault2016-04-292-5/+26
| | | | | | | | | This was being treated the same as private, which has an immediate offset. For unknown, it probably means it's for a computation not actually being used for accessing memory, so it should not have a nontrivial addressing mode. llvm-svn: 268002

| | | | | | | | | | | | | | In case of missing live intervals for a physical registers getLanesWithProperty() would report 0 which was not a safe default in all situations. Add a parameter to pass in a safe default. No testcase because in-tree targets do not skip computing register unit live intervals. Also cleanup the getXXX() functions to not perform the RequireLiveIntervals checks anymore so we do not even need to return safe defaults. llvm-svn: 267977
* RegisterPressure: Cannot produce dead (subregister) defs anymoreMatthias Braun2016-04-291-3/+2
| | | | | | | | | With the DetectDeadLanes pass in place we cannot run into situations anymore where defs suddenly become dead. Also add a missing check so we do not try to add an undef flag to a physreg (found by visual inspection, no failing test). llvm-svn: 267976

* [LoopVectorize] Keep hints from original loop on the vector loopHal Finkel2016-04-292-0/+35
| | | | | | | | | | | | | | | | We need to keep loop hints from the original loop on the new vector loop. Failure to do this meant that, for example: void foo(int *b) { #pragma clang loop unroll(disable) for (int i = 0; i < 16; ++i) b[i] = 1; } this loop would be unrolled. Why? Because we'd vectorize it, thus dropping the hints that unrolling should be disabled, and then we'd unroll it. llvm-svn: 267970

* LiveIntervalAnalysis: Remove LiveVariables requirementMatthias Braun2016-04-284-8/+11
| | | | | | | | | | | | This requirement was a huge hack to keep LiveVariables alive because it was optionally used by TwoAddressInstructionPass and PHIElimination. However we have AnalysisUsage::addUsedIfAvailable() which we can use in those passes. This re-applies r260806 with LiveVariables manually added to PowerPC to hopefully not break the stage 2 bots this time. llvm-svn: 267954

* [LoopDist] Emit optimization remarks (-Rpass*)Adam Nemet2016-04-282-0/+143
| | | | | | | | | | | | | | | | I closely followed the precedents set by the vectorizer: * With -Rpass-missed, the loop is reported with further details pointing to -Rpass--analysis. * -Rpass-analysis reports the details why distribution has failed. * Regardless of -Rpass*, when distribution fails for a loop where distribution was forced with the pragma, a warning is produced according to -Wpass-failed. In this case the analysis info is also printed even without -Rpass-analysis. llvm-svn: 267952
* [LoopDist] Improve debug messagesAdam Nemet2016-04-281-6/+6
| | | | | | | | | | | The next patch will start using these for -Rpass-analysis so they won't be internal-only anymore. Move the 'Skipping; ' prefix that some of the message are using into the 'fail' function. We don't want to include this prefix in the -Rpass-analysis report. llvm-svn: 267951
* [LoopDist] Add helper to print debug message when distribution fails. NFCAdam Nemet2016-04-281-23/+20

* [Inliner] Preserve llvm.mem.parallel_loop_access metadataHal Finkel2016-04-282-0/+88
| | | | | | | | | | | | | | | | | | | | | | | When inlining a call site with llvm.mem.parallel_loop_access metadata, this metadata needs to be propagated to all cloned memory-accessing instructions. Otherwise, inlining parts of the loop body will invalidate the annotation. With this functionality, we now vectorize the following as expected: void Body(int *res, int *c, int *d, int *p, int i) { res[i] = (p[i] == 0) ? res[i] : res[i] + d[i]; } void Test(int *res, int *c, int *d, int *p, int n) { int i; #pragma clang loop vectorize(assume_safety) for (i = 0; i < 1600; i++) { Body(res, c, d, p, i); } } llvm-svn: 267949

* [PowerPC] Fix the EH_SjLj_Setup pseudo.Marcin Koscielnicki2016-04-283-1/+54
| | | | | | | | | | | | | | | | | | | This instruction is just a control flow marker - it should not actually exist in the object file. Unfortunately, nothing catches it before it gets to AsmPrinter. If integrated assembler is used, it's considered to be a normal 4-byte instruction, and emitted as an all-0 word, crashing the program. With external assembler, a comment is emitted. Fixed by setting Size to 0 and handling it in MCCodeEmitter - this means the comment will still be emitted if integrated assembler is not used. This broke an ASan test, which has been disabled for a long time as a result (see the discussion on D19657). We can reenable it once this lands. llvm-svn: 267943
