Prepare for LLVM 11 These are just the code changes needed to build with the current LLVM master (version 11). r? @nikic
2020-06-26Rollup merge of #72620 - tmiasko:linkage-name, r=eddybManish Goregaokar-0/+42
Omit DW_AT_linkage_name when it is the same as DW_AT_name The DWARF standard suggests that it might be useful to include `DW_AT_linkage_name` when it is *distinct* from the identifier name. Fixes #46487. Fixes #59422.

This keeps FileCheck from tripping over unimportant differences in codegen.

..which doesn't use variant types.
2020-06-24Generalize generator-debug test a bitTyler Mandry-21/+19
Don't be so reliant on particular line ordering (though FileCheck makes this hard in general, IMO). Also disable for MSVC.

memory access sanity checks: abort instead of panic Suggested by @Mark-Simulacrum, this should help reduce the performance impact of these checks.
2020-06-19Rollup merge of #73044 - tmiasko:compiletest-san, r=nikomatsakisRalf Jung-11/+6
compiletest: Add directives to detect sanitizer support Add needs-sanitizer-{address,leak,memory,thread} directive indicating that test requires target with support for specific sanitizer. This is an addition to the existing needs-sanitizer-support directive indicating that test requires a sanitizer runtime library. The existing needs-sanitizer-support directive could be incorporated into the new ones, but I decided to retain it, since it enables running sanitizer codegen tests even when building of sanitizer runtime libraries is disabled.

2020-06-07Rollup merge of #72977 - tblah:riscv-codegen-llvm10, r=nikomatsakisDylan DPC-41/+93
Fix codegen tests for RISC-V Some codegen tests didn't seem relevant (e.g. unsupported annotations). The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1) I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.

LLVM 10 includes a009a60a917bc30940422bcef73f8270566d78db which will print value numbers for unnamed func args. Update these tests to be in line with the referenced clang tests.

2020-05-21Auto merge of #71718 - NeoRaider:ffi_const_pure, r=Amanieubors-0/+24
Experimentally add `ffi_const` and `ffi_pure` extern fn attributes Add FFI function attributes corresponding to clang/gcc/... `const` and `pure`. Rebased version of #58327 by @gnzlbg with the following changes: - Switched back from the `c_ffi_const` and `c_ffi_pure` naming to `ffi_const` and `ffi_pure`, as I agree with https://github.com/rust-lang/rust/pull/58327#issuecomment-462718772 and this nicely aligns with `ffi_returns_twice` - (Hopefully) took care of all of @hanna-kruppe's change requests in the original PR r? @hanna-kruppe
2020-05-21Auto merge of #72205 - ecstatic-morse:nrvo, r=oli-obkbors-2/+19
Dumb NRVO This is a very simple version of an NRVO pass, which scans backwards from the `return` terminator to see if there is an an assignment like `_0 = _1`. If a basic block with two or more predecessors is encountered during this scan without first seeing an assignment to the return place, we bail out. This avoids running a full "reaching definitions" dataflow analysis. I wanted to see how much `rustc` would benefit from even a very limited version of this optimization. We should be able to use this as a point of comparison for more advanced versions that are based on live ranges. r? @ghost
2020-05-20Rollup merge of #72139 - nnethercote:standalone-fold, r=cuviperDylan DPC-24/+0
Make `fold` standalone. `fold` is currently implemented via `try_fold`, but implementing it directly results in slightly less LLVM IR being generated, speeding up compilation of some benchmarks. r? @cuviper

2020-05-18Make `fold` standalone.Nicholas Nethercote-24/+0
`fold` is currently implemented via `try_fold`, but implementing it directly results in slightly less LLVM IR being generated, speeding up compilation of some benchmarks. (And likewise for `rfold`.) The commit adds `fold` implementations to all the iterators that lack one but do have a `try_fold` implementation. Most of these just call the `try_fold` implementation directly.
