AArch64/ARM64: move ARM64 into AArch64's place This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577

[ARM][AArch64] Armv8.4-A Enablement Initial patch adding assembly support for Armv8.4-A. Besides adding v8.4 as a supported architecture to the usual places, this also adds target features for the different crypto algorithms. Armv8.4-A introduced new crypto algorithms, made them optional, and allows different combinations: - none of the v8.4 crypto functions are supported, which is independent of the implementation of the Armv8.0 SHA1 and SHA2 instructions. - the v8.4 SHA512 and SHA3 support is implemented, in this case the Armv8.0 SHA1 and SHA2 instructions must also be implemented. - the v8.4 SM3 and SM4 support is implemented, which is independent of the implementation of the Armv8.0 SHA1 and SHA2 instructions. - all of the v8.4 crypto functions are supported, in this case the Armv8.0 SHA1 and SHA2 instructions must also be implemented. The v8.4 crypto instructions are added to AArch64 only, and not AArch32, and are made optional extensions to Armv8.2-A. The user-facing Clang options will map on these new target features, their naming will be compatible with GCC and added in follow-up patches.

[AArch64] Add subtarget features for ARMv8.2-A This adds subtarget features for ARMv8.2-A, which builds on (and requires the features from) ARMv8.1-A.

There is also one large, optional feature, which adds 16-bit floating point versions of all existing floating-point instructions (VFP and SIMD), this is represented by the FeatureFullFP16 subtarget feature.

AArch64: Do not test for CPUs, use SubtargetFeatures Testing for specific CPUs has a number of problems, better use subtarget features: - When some tweak is added for a specific CPU it is often desirable for the next version of that CPU as well, yet we often forget to add it. - It is hard to keep track of checks scattered around the target code; Declaring all target specifics together with the CPU in the tablegen file is a clear representation. - Subtarget features can be tweaked from the command line. To discourage people from using CPU checks in the future I removed the isCortexXX(), isCyclone(), ... functions. I added an getProcFamily() function for exceptional circumstances but made it clear in the comment that usage is discouraged. Reformat feature list in AArch64.td to have 1 feature per line in alphabetical order to simplify merging and sorting for out of tree tweaks. No functional change intended.

[ARM][AArch64] Armv8.4-A Enablement Initial patch adding assembly support for Armv8.4-A. Besides adding v8.4 as a supported architecture to the usual places, this also adds target features for the different crypto algorithms. Armv8.4-A introduced new crypto algorithms, made them optional, and allows different combinations: - none of the v8.4 crypto functions are supported, which is independent of the implementation of the Armv8.0 SHA1 and SHA2 instructions. - the v8.4 SHA512 and SHA3 support is implemented, in this case the Armv8.0 SHA1 and SHA2 instructions must also be implemented. - the v8.4 SM3 and SM4 support is implemented, which is independent of the implementation of the Armv8.0 SHA1 and SHA2 instructions. - all of the v8.4 crypto functions are supported, in this case the Armv8.0 SHA1 and SHA2 instructions must also be implemented. The v8.4 crypto instructions are added to AArch64 only, and not AArch32, and are made optional extensions to Armv8.2-A. The user-facing Clang options will map on these new target features, their naming will be compatible with GCC and added in follow-up patches.

AArch64: TableGenerate system instruction operands. The way the named arguments for various system instructions are handled at the moment has a few problems: - Large-scale duplication between AArch64BaseInfo.h and AArch64BaseInfo.cpp - That weird Mapping class that I have no idea what I was on when I thought it was a good idea. - Searches are performed linearly through the entire list. - We print absolutely all registers in upper-case, even though some are canonically mixed case (SPSel for example). - The ARM ARM specifies sysregs in terms of 5 fields, but those are relegated to comments in our implementation, with a slightly opaque hex value indicating the canonical encoding LLVM will use. This adds a new TableGen backend to produce efficiently searchable tables, and switches AArch64 over to using that infrastructure. llvm-svn: 274576

AArch64: Do not test for CPUs, use SubtargetFeatures Testing for specific CPUs has a number of problems, better use subtarget features: - When some tweak is added for a specific CPU it is often desirable for the next version of that CPU as well, yet we often forget to add it. - It is hard to keep track of checks scattered around the target code; Declaring all target specifics together with the CPU in the tablegen file is a clear representation. - Subtarget features can be tweaked from the command line. To discourage people from using CPU checks in the future I removed the isCortexXX(), isCyclone(), ... functions. I added an getProcFamily() function for exceptional circumstances but made it clear in the comment that usage is discouraged.

Work around the issue conservatively by avoiding the instruction entirely. This patch changes CodeGen so that problematic instructions are never generated, and the AsmParser so that an equivalent instruction is used (with a warning). llvm-svn: 320965

Summary: Scheduling AESE/AESMC and AESD/AESIMC instruction pairs back-to-back gives a double digit speedup on benchmarks using those instructions on Cortex-A processors. In GCC, this optimization is part of the generic processor model as well. This change should not have a major performance impact on processors that do not optimize AES instruction pairs, although I only had access to Cortex-A processors for benchmarking.

FeatureFuseAES,
AArch64: Do not test for CPUs, use SubtargetFeatures Testing for specific CPUs has a number of problems, better use subtarget features: - When some tweak is added for a specific CPU it is often desirable for the next version of that CPU as well, yet we often forget to add it. - It is hard to keep track of checks scattered around the target code; Declaring all target specifics together with the CPU in the tablegen file is a clear representation. - Subtarget features can be tweaked from the command line. To discourage people from using CPU checks in the future I removed the isCortexXX(), isCyclone(), ... functions. I added an getProcFamily() function for exceptional circumstances but made it clear in the comment that usage is discouraged. Reformat feature list in AArch64.td to have 1 feature per line in alphabetical order to simplify merging and sorting for out of tree tweaks. No functional change intended.

[AArch64] Restore codegen for AArch64 Cortex-A72/A73 after NFCI Summary: Code generation for Cortex-A72/Cortex-A73 was accidentally changed by r271555, which was a NFCI. The isCortexA57() predicate was not true for Cortex-A72/Cortex-A73 before r271555 (since it was checking the CPU string). Because Cortex-A72/Cortex-A73 inherit all features from Cortex-A57, all decisions previously guarded by isCortexA57() are now taken. This change restores the behaviour before r271555 by adding separate ProcA72/ProcA73, which have the required features to preserve code generation.

[MCInstPrinter] Enable MCInstPrinter to change its behavior based on the per-function subtarget. Currently, code-gen passes the default or generic subtarget to the constructors of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which enables some targets (AArch64, ARM, and X86) to change their instprinter's behavior based on the subtarget feature bits. Since the backend can now use different subtargets for each function, instprinter has to be changed to use the per-function subtarget rather than the default subtarget. This patch takes the first step towards enabling instprinter to change its behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the various print methods table-gen auto-generates.

[MachineOperand][Target] MachineOperand::isRenamable semantics changes Summary: Add a target option AllowRegisterRenaming that is used to opt in to post-register-allocation renaming of registers. This is set to 0 by default, which causes the hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq fields of all opcodes to be set to 1, causing MachineOperand::isRenamable to always return false. Set the AllowRegisterRenaming flag to 1 for all in-tree targets that have lit tests that were effected by enabling COPY forwarding in MachineCopyPropagation (AArch64, AMDGPU, ARM, Hexagon, Mips, PowerPC, RISCV, Sparc, SystemZ and X86). Add some more comments describing the semantics of the MachineOperand::isRenamable function and how it is set and maintained. Change isRenamable to check the operand's opcode hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq bit directly instead of relying on it being consistently reflected in the IsRenamable bit setting. Clear the IsRenamable bit when changing an operand's register value. Remove target code that was clearing the IsRenamable bit when changing registers/opcodes now that this is done conservatively by default. Change setting of hasExtraSrcRegAllocReq in AMDGPU target to be done in one place covering all opcodes that have constant pipe read limit restrictions.
