2020-07-17Generating the coverage mapRich Kadel-5/+6
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|}
2020-06-29add spans to injected coverage countersRich Kadel-0/+5
added regions with counter expressions and counters. Added codegen_llvm/coverageinfo mod for upcoming coverage map Move coverage region collection to CodegenCx finalization Moved from `query coverageinfo` (renamed from `query coverage_data`), as discussed in the PR at: https://github.com/rust-lang/rust/pull/73684#issuecomment-649882503 Address merge conflict in MIR instrument_coverage test The MIR test output format changed for int types. moved debug messages out of block.rs This makes the block.rs calls to add coverage mapping data to the CodegenCx much more concise and readable. move coverage intrinsic handling into llvm impl I realized that having half of the coverage intrinsic handling in `rustc_codegen_ssa` and half in `rustc_codegen_llvm` meant that any non-llvm backend would be bound to the same decisions about how the coverage-related MIR terminators should be handled. To fix this, I moved the non-codegen portion of coverage intrinsic handling into its own trait, and implemented it in `rustc_codegen_llvm` alongside `codegen_intrinsic_call`. I also added the (required?) stubs for the new intrinsics to `IntrepretCx::emulate_intrinsic()`, to ensure calls to this function do not fail if called with these new but known intrinsics. address PR Feedback on 28 June 2020 2:48pm PDT
2020-06-14Diagnose use of incompatible sanitizersTomasz Miąsko-3/+3
Emit an error when incompatible sanitizer are configured through command line options. Previously the last one configured prevailed and others were silently ignored. Additionally use a set to represent configured sanitizers, making it possible to enable multiple sanitizers at once. At least in principle, since currently all of them are considered to be incompatible with others.

2019-04-30Move metadata encoding earlier.Nicholas Nethercote-36/+4
This commit separates metadata encoding (`tcx.encode_metadata`) from the creation of the metadata module (which is now handled by `write_compressed_metadata`, formerly `write_metadata`). The metadata encoding now occurs slightly earlier in the pipeline, at the very start of code generation within `start_codegen`. Metadata *writing* still occurs near the end of compilation; that will be moved forward in subsequent commits.
