2020-07-17Generating the coverage mapRich Kadel-1/+43
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|}

2019-12-12Fix weird implicit dependency between rustllvm and rustc_codegen_llvmAaron Hill-17/+2
rustllvm relies on the `LLVMRustStringWriteImpl` symbol existing, but this symbol was previously defined in a *downstream* crate (rustc_codegen_llvm, which depends on rustc_llvm. While this somehow worked under the old 'separate bootstrap step for codegen' scheme, it meant that rustc_llvm could not actually be built by itself, since it relied linking to the downstream rustc_codegen_llvm crate. Now that librustc_codegen_llvm is just a normal crate, we actually try to build a standalone rustc_llvm when we run tests. This commit moves `LLVMRustStringWriteImpl` into rustc_llvm (technically the rustllvm directory, which has its contents built by rustc_llvm). This ensures that we can build each crate in the graph by itself, without requiring that any downstream crates be linked in as well.
2019-12-04Migrate to LLVM{Get,Set}ValueName2Josh Stone-1/+19
The deprecated `LLVM{Get,Set}ValueName` only work with NUL-terminated strings, but the `2` variants use explicit lengths, which fits better with Rust strings and slices. We now use these in new helper functions `llvm::{get,set}_value_name` that convert to/from `&[u8]`.
