Move `rustllvm` into `rustc_llvm`

2020-09-09T20:05:43+00:00

Remove AsmDialect::Other

2020-08-12T15:59:17+00:00

Added in #35174, this was already unused (and new uses have not been introduced since then).

Remove SynchronizationScope::Other

Added in b7615389978eae2ae9f3cba9a776fd8da3f743ca, it started out already unused.

Generating the coverage map

2020-07-17T18:49:35+00:00

rustc now generates the coverage map and can support (limited) coverage report generation, at the function level. Example: $ BUILD=$HOME/rust/build/x86_64-unknown-linux-gnu $ $BUILD/stage1/bin/rustc -Zinstrument-coverage \ $HOME/rust/src/test/run-make-fulldeps/instrument-coverage/main.rs $ LLVM_PROFILE_FILE="main.profraw" ./main called $ $BUILD/llvm/bin/llvm-profdata merge -sparse main.profraw -o main.profdata $ $BUILD/llvm/bin/llvm-cov show --instr-profile=main.profdata main 1| 1|pub fn will_be_called() { 2| 1| println!("called"); 3| 1|} 4| | 5| 0|pub fn will_not_be_called() { 6| 0| println!("should not have been called"); 7| 0|} 8| | 9| 1|fn main() { 10| 1| let less = 1; 11| 1| let more = 100; 12| 1| 13| 1| if less < more { 14| 1| will_be_called(); 15| 1| } else { 16| 1| will_not_be_called(); 17| 1| } 18| 1|}

Rollup merge of #73715 - MaulingMonkey:pr-natvis-tuples, r=Amanieu

2020-07-11T15:53:13+00:00

debuginfo: Mangle tuples to be natvis friendly, typedef basic types These changes are meant to unblock rust-lang/rust#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.) * f8eb81b does the actual mangling of `(u64, u64)` -> `tuple` * 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap`)

Prepare for LLVM 11

2020-06-26T01:52:41+00:00

debuginfo: Define int/float types in terms of MSVC-recognized types.

2020-06-25T06:28:00+00:00

PDB debug information doesn't appear to be emitted for basic types. By defining u32 as a typedef for unsigned __int32 when targeting MSVC, we allow CDB and other debuggers to recognize "u32" as a type/expression. This in turn unblocks rust-lang#70052 "Update hashbrown to 0.8.0" by allowing $T1 ..= $T3 to resolve, which would otherwise fail to resolve when builtin types fail to parse.

[WIP] injects llvm intrinsic instrprof.increment for coverage reports

2020-06-15T23:50:10+00:00

This initial version only injects counters at the top of each function. Rust Coverage will require injecting additional counters at each conditional code branch.

Handle assembler warnings properly

2020-06-09T14:01:02+00:00

Improve inline asm error diagnostics
