Commit 26947d7b63809413b96b0bb6033f168488836289 by ro [tools][remarks-shlib] Don't build libRemarks.so without PIC A build on `sparcv9-sun-solaris2.11` with `-DLLVM_ENABLE_PIC=Off` failed linking `libRemarks.so`: [27/2297] Linking CXX shared library lib/libRemarks.so.12git FAILED: lib/libRemarks.so.12git [...] ld: fatal: relocation error: R_SPARC_H44: file lib/libLLVMRemarks.a(Remark.cpp.o): symbol _ZTVN4llvm18raw_string_ostreamE: invalid shared object relocation type: ABS44 code model unsupported [...] On Solaris/sparcv9 as on many other targets you cannot link non-PIC objects into a shared object. The following patch avoids this by not building the library with PIC. It allowed the build to complete and `ninja check-all` showed no errors. Differential Revision: https://reviews.llvm.org/D85626

Commit e17686ae60faa85857e61052632bb6e6c0230ae0 by llvm-dev [X86] Rename combineExtInVec to combineEXTEND_VECTOR_INREG. NFCI. Make it easier to find the method by naming it after the ops it actually handles. We already do this for lowering.

Commit a735d6eae2847b039d12c75d4c794862dad59bc1 by llvm-dev JSONCompilationDatabase.cpp - cleanup key parsing error checks. NFCI. Merge the key + sequence/value checks with the key handling code. Reduces the number of key string comparisons and avoids a number of clang static analyzer null dereference warnings.

Commit 91720ee561b2da4161df6abaddfd8a677aebb504 by llvm-dev [X86] combineX86ShufflesRecursively - fix use after move warning. NFCI. After moving WidenedMask is in an undefined state, so reduce scope of the variable so its reinitialized every iteration - we should still retain any memory allocation savings.

Commit 6bb912336804822cc4b09f6849f1fd7d12057132 by llvm-dev DWARFYAML::emitDebugSections - fix use after std::move warnings. NFCI. We were using Err after it had been moved into cantFail - avoid this by calling cantFail with Error::success() directly.

Commit a0c8793ce691d77453bca9d31b0031d39d07a5b4 by llvm-dev [X86][SSE] Enable ZERO_EXTEND_VECTOR_INREG shuffle combining on SSE41 targets. Allows ZERO_EXTEND_VECTOR_INREG to be shuffle combined on all targets where it is legal.

Commit 15c8306056beefa61533a895e8d836db72fccd14 by llvm-dev [X86][SSE] Fold EXTEND_VECTOR_INREG(EXTEND_VECTOR_INREG(X)) -> EXTEND_VECTOR_INREG(X) It should be possible to make this generic, but we're not great at checking legality of *_EXTEND_VECTOR_INREG ops so I'm conservatively putting this inside X86ISelLowering.cpp
