| | | | | | | | | | | | | | | | | | | | | | Summary: Some custom mutators may not peform well when size restriction is enforced by len_control. Because of that, it's safer to disable len_control by default in such cases, but still allow users to enable it manually. Bug example: https://bugs.chromium.org/p/chromium/issues/detail?id=919530. Tested manually with LPM-based and regular fuzz targets.

* gn build: Add NVPTX targetNico Weber2019-06-149-4/+167
| | | | | | | | | | | | | | | | | | | The NVPTX target is a bit unusual in that it's the only target without a disassembler, and one of three targets without an asm parser (and the first one of those three in the gn build). NVPTX doesn't have those because it's not a binary format. The CMake build checks for the existence of {AsmParser,Disassembler}/CMakeLists.txt when setting LLVM_ENUM_ASM_PARSERS / LLVM_ENUM_DISASSEBLERS (http://llvm-cs.pcc.me.uk/CMakeLists.txt#744). The GN build doesn't want to hit the disk for things like this, so instead I'm adding explicit `targets_with_asm_parsers` and `targets_with_disassemblers` lists. Since both are needed rarely, they are defined in their own gni files. Differential Revision: https://reviews.llvm.org/D63210 llvm-svn: 363437
* gn build: Simplify Target build filesNico Weber2019-06-1421-159/+73
| | | | | | | | | | | | | | | | Now that the cycle between MCTargetDesc and TargetInfo is gone (see revisions 360709 360718 360722 360724 360726 360731 360733 360735 360736), remove the dependency from TargetInfo on MCTargetDesc:tablegen. In most targets, this makes MCTargetDesc:tablegen have just a single use, so inline it there. For AArch64, ARM, and RISCV there's still a similar cycle between MCTargetDesc and Utils, so the MCTargetDesc:tablegen indirection is still needed there.

* C++ DR712 and others: handle non-odr-use resulting from an lvalue-to-rvalue ↵Richard Smith2019-06-1412-91/+714
| | | | | | | | | | | | | | | | | | | | | | | | | | | conversion applied to a member access or similar not-quite-trivial lvalue expression. Summary: When a variable is named in a context where we can't directly emit a reference to it (because we don't know for sure that it's going to be defined, or it's from an enclosing function and not captured, or the reference might not "work" for some reason), we emit a copy of the variable as a global and use that for the known-to-be-read-only access. This reinstates r363295, reverted in r363352, with a fix for PR42276: we now produce a proper name for a non-odr-use reference to a static constexpr data member. The name <mangled-name>.const is used in that case; such names are reserved to the implementation for cases such as this and should demangle nicely.

| | | | | | | | | | | When cross-compiling LLVM to android from Windows (for LLVMSupport), we would attempt to execute `config.guess` to determine the host triple since `CMAKE_SYSTEM_NAME` is not Windows and `CMAKE_C_COMPILER` will be set to GNU or Clang.

* [FPEnv] Lower STRICT_FP_EXTEND and STRICT_FP_ROUND nodes in preprocess phase ↵Kevin P. Neal2019-06-142-45/+171
| | | | | | | | | | | | | of ISelLowering to mirror non-strict nodes on x86. I recently discovered a bug on the x86 platform: The fp80 type was not handled well by x86 for constrained floating point nodes, as their regular counterparts are replaced by extending loads and truncating stores during the preprocess phase. Normally, platforms don't have this issue, as they don't typically attempt to perform such legalizations during instruction selection preprocessing. Before this change, strict_fp nodes survived until they were mutated to normal nodes, which happened shortly after preprocessing on other platforms. This modification lowers these nodes at the same phase while properly utilizing the chain.5 Submitted by: Drew Wock <drew.wock@sas.com> Reviewed by: Craig Topper, Kevin P.

* GlobalISel: Avoid producing Illegal copies in RegBankSelectMatt Arsenault2019-06-146-35/+262
| | | | | | | | | | | | | | | | | | | | | | Avoid producing illegal register bank copies for reg_sequence and phi. The default implementation assumes it is possible to pick any operand's bank and use that for the result, introducing a copy for operands with a different bank. This does not check for illegal copies. It is not legal to introduce a VGPR->SGPR copy, so any VGPR operand requires the result to be a VGPR. The changes in getInstrMappingImpl aren't strictly necessary, since AMDGPU now just bypasses this for reg_sequence/phi. This could be replaced with an assert in case other targets run into this. It is currently responsible for producing the error for unsatisfiable copies, but this will be better served with a verifier check. For phis, for now assume any undetermined operands must be VGPRs. Eventually, this needs to be able to defer mapping these operations. This also does not yet have a way to check for whether the block is in a divergent region. llvm-svn: 363410
