rust/compiler/rustc_llvm/llvm-wrapper/RustWrapper.cpp, branch 1.49.0

Rollup merge of #77950 - arlosi:sha256, r=eddyb

2020-11-03T18:32:26+00:00

Add support for SHA256 source file hashing Adds support for `-Z src-hash-algorithm sha256`, which became available in LLVM 11. Using an older version of LLVM will cause an error `invalid checksum kind` if the hash algorithm is set to sha256. r? `@eddyb` cc #70401 `@est31`

Use unwrapDIPtr because the Scope may be null. I ran into an assertion when using debug information on Windows with LLVM assertions enabled. It seems like we are using unwrap here (which in turn calls isa and requires the pointer to be non-null) but we expect the value to be null because that is what we are passing from rustc. This change uses unwrapDIPtr which explicitly allows nullptr. The FFI prototype for this method on the rust side has the `LLVMMetadataRef` parameter as `Scope: Option<&'a DIScope>`, and we always pass `None` when `msvc_like_names` is true.

Use unwrapDIPtr because the Scope may be passed as None

rustc_codegen_llvm: avoid converting between DILocation and Value.

rustc_codegen_llvm: move DISubprogram creation to a dbg_scope_fn method.

Update LLVM and add Unsupported diagnostic

2020-09-30T13:57:37+00:00

Secure entry functions do not support if arguments are passed on the stack. An "unsupported" diagnostic will be emitted by LLVM if that is the case. This commits adds support in Rust for that diagnostic so that an error will be output if that is the case! Signed-off-by: Hugues de Valon

Move `rustllvm` into `rustc_llvm`
