* [PowerPC][NFC] Add tests for vector fp <-> int conversionsNemanja Ivanovic2018-11-1616-0/+14768
| | | | | | | | | This NFC patch just adds test cases for conversions that currently require scalarization of vectors. An updcoming patch will change the legalization for these and it is more suitable on the review to show the diferences in code gen rather than just the new code gen. llvm-svn: 347090
* AArch64: Emit a call frame instruction for the shadow call stack register.Peter Collingbourne2018-11-162-6/+26
| | | | | | | | | | When unwinding past a function that uses shadow call stack, we must subtract 8 from the value of the x18 register. This patch causes us to emit a call frame instruction that causes that to happen. Differential Revision: https://reviews.llvm.org/D54609 llvm-svn: 347089

The type merging phase of PDB writing goes from 10s to 3s. This removes the LLVM cl::opt and replaces it with a metadata flag.

| | | | | | | | | | | | | This saves about 3 redundant gigabytes from the Objective-C test build directories.

* Makefile.rules: Use a shared clang module cache directory.Adrian Prantl2018-11-162-2/+19
| | | | | | | | | | | | | | | Just to be safe, up until now each test used its own Clang module cache directory. Since the compiler within one testsuite doesn't change it is just as safe to share a clang module directory inside the LLDB test build directory. This saves us from compiling tens of gigabytes of redundant Darwin and Foundation .pcm files and also speeds up running the test suite quite significantly. rdar://problem/36002081 Differential Revision: https://reviews.llvm.org/D54601 llvm-svn: 347056

* [X86] X86DAGToDAGISel::matchBitExtract(): extract 'lshr' from `X`Roman Lebedev2018-11-162-231/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: As discussed in previous review, and noted in the FIXME, if `X` is actually an `lshr Y, Z` (logical!), we can fold the `Z` into 'control`, and let the `BEXTR` do this too. We could just insert those 8 bits of shift amount into control, but it is better to instead zero-extend them, and 'or' them in place. We can only do this for `lshr`, not `ashr`, because we do not know that the mask cover only the bits of `Y`, and not any of the sign-extended bits. The obvious question is, is this actually legal to do? I believe it is. Relevant quotes, from `Intel® 64 and IA-32 Architectures Software Developer’s Manual`, `BEXTR — Bit Field Extract`: * `Bit 7:0 of the second source operand specifies the starting bit position of bit extraction.` * `A START value exceeding the operand size will not extract any bits from the second source operand.` * `Only bit positions up to (OperandSize -1) of the first source operand are extracted.` * `All higher order bits in the destination operand (starting at bit position LENGTH) are zeroed.` * `The destination register is cleared if no bits are extracted.` FIXME: if we can do this, i wonder if we should prefer `BEXTR` over `BZHI` in such cases.

* [RISCV] Constant materialisation for RV64IAlex Bradbury2018-11-162-8/+232
| | | | | | | | | | | | | | | | | | | | | | | This commit introduces support for materialising 64-bit constants for RV64I, making use of the RISCVMatInt::generateInstSeq helper in order to share logic for immediate materialisation with the MC layer (where it's used for the li pseudoinstruction). test/CodeGen/RISCV/imm.ll is updated to test RV64, and gains new 64-bit constant tests. It would be preferable if anyext constant returns were sign rather than zero extended (see PR39092). This patch simply adds an explicit signext to the returns in imm.ll. Further optimisations for constant materialisation are possible, most notably for mask-like values which can be generated my loading -1 and shifting right. A future patch will standardise on the C++ codepath for immediate selection on RV32 as well as RV64, and then add further such optimisations to RISCVMatInt::generateInstSeq in order to benefit both RV32 and RV64 for codegen and li expansion.
