2012-07-05Finish fixing the MachineOperand hashing, providing a nice modernChandler Carruth
hash_value overload for MachineOperands. This addresses a FIXME sufficient for me to remove it, and cleans up the code nicely too. The important changes to the hashing logic: - TargetFlags are now included in all of the hashes. These were complete missed. - Register operands have their subregisters and whether they are a def included in the hash. - We now actually hash all of the operand types. Previously, many operand types were simply *dropped on the floor*. For example: - Floating point immediates - Large integer immediates (>64-bit) - External globals! - Register masks - Metadata operands - It removes the offset from the block-address hash; I'm a bit suspicious of this, but isIdenticalTo doesn't consider the offset for black addresses. Any patterns involving these entities could have triggered extreme slowdowns in MachineCSE or PHIElimination. Let me know if there are PRs you think might be closed now... I'm looking myself, but I may miss them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159743 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-04Add an experimental early if-conversion pass, off by default.Jakob Stoklund Olesen
This pass performs if-conversion on SSA form machine code by speculatively executing both sides of the branch and using a cmov instruction to select the result. This can help lower the number of branch mispredictions on architectures like x86 that don't have predicable instructions. The current implementation is very aggressive, and causes regressions on mosts tests. It needs good heuristics that have yet to be implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159694 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Extend TargetPassConfig to allow running only a subset of the normal passes.Bob Wilson
This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Make NumMicroOps a variable in the subtarget's instruction itinerary.Andrew Trick
The TargetInstrInfo::getNumMicroOps API does not change, but soon it will be used by MachineScheduler. Now each subtarget can specify the number of micro-ops per itinerary class. For ARM, this is currently always dynamic (-1), because it is used for load/store multiple which depends on the number of register operands. Zero is now a valid number of micro-ops. This can be used for nop pseudo-instructions or instructions that the hardware can squash during dispatch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159406 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-28Allow BBVectorize to form non-2^n-length vectors.Hal Finkel
The original algorithm only used recursive pair fusion of equal-length types. This is now extended to allow pairing of any types that share the same underlying scalar type. Because we would still generally prefer the 2^n-length types, those are formed first. Then a second set of iterations form the non-2^n-length types. Also, a call to SimplifyInstructionsInBlock has been added after each pairing iteration. This takes care of DCE (and a few other things) that make the following iterations execute somewhat faster. For the same reason, some of the simple shuffle-combination cases are now handled internally. There is some additional refactoring work to be done, but I've had many requests for this feature, so additional refactoring will come soon in future commits (as will additional test cases). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159330 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-27The ELF relocation record format is different for N64 Jack Carter
which many Mips 64 ABIs use than for O64 which many if not all other target ABIs use. Most architectures have the following 64 bit relocation record format: typedef struct { Elf64_Addr r_offset; /* Address of reference */ Elf64_Xword r_info; /* Symbol index and type of relocation */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset; Elf64_Xword r_info; Elf64_Sxword r_addend; } Elf64_Rela; Whereas N64 has the following format: typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ } Elf64_Rel; typedef struct { Elf64_Addr r_offset;/* Address of reference */ Elf64_Word r_sym; /* Symbol index */ Elf64_Byte r_ssym; /* Special symbol */ Elf64_Byte r_type3; /* Relocation type */ Elf64_Byte r_type2; /* Relocation type */ Elf64_Byte r_type; /* Relocation type */ Elf64_Sxword r_addend; } Elf64_Rela; The structure is the same size, but the r_info data element is now 5 separate elements. Besides the content aspects, endian byte reordering will be different for the area with each element being endianized separately. I treat this as generic and continue to pass r_type as an integer masking and unmasking the byte sized N64 values for N64 mode. I've implemented this and it causes no affect on other current targets. This passes make check. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159299 91177308-0d34-0410-b5e6-96231b3b80d8
