[compiletest] Use the correct rustc lib directory for query_rustc_output - #161335
Merged
Conversation
ui-fulldeps tests are built with the stage0 compiler, but query_rustc_output uses the stage1 compiler. This caused segfaults on my machine, as the stage1 compiler (which uses LLVM 23) was run with the stage0 lib directory (which has LLVM 22). Fix this by providing compiletest with the lib directory to use for query_rustc_output.

Yep, that stage 0 lib path definitely is wrong. |

that `DYLD_LIBRARY_PATH` contains `rust/build/aarch64-apple-darwin/stage0/lib`, while the compiler we're executing is `rust/build/aarch64-apple-darwin/stage1/bin/rustc`. This PR fixes the issue by providing compiletest with the correct lib directory to use when querying the stage1 compiler. I expect the problem will go away again once rust-lang#161325 is merged and stage0 and stage1 use the same LLVM version, but this PR ensures it won't be a problem for the next LLVM bump. I encountered a similar issue building the unstable book, which I am planning to submit a followup PR for.

that `DYLD_LIBRARY_PATH` contains `rust/build/aarch64-apple-darwin/stage0/lib`, while the compiler we're executing is `rust/build/aarch64-apple-darwin/stage1/bin/rustc`. This PR fixes the issue by providing compiletest with the correct lib directory to use when querying the stage1 compiler. I expect the problem will go away again once #161325 is merged and stage0 and stage1 use the same LLVM version, but this PR ensures it won't be a problem for the next LLVM bump. I encountered a similar issue building the unstable book, which I am planning to submit a followup PR for.

ui-fulldeps tests are built with the stage0 compiler, but invoke the stage1 compiler to determine target features. This caused segfaults on my machine, as the stage1 compiler (which uses LLVM 23) was run with the stage0 lib directory (which has LLVM 22):
