llc crashes linking regex test suite under emscripten #37952

Labels
A-LLVM Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues. C-bug Category: This is a bug. I-crash Issue: The compiler crashes (SIGSEGV, SIGABRT, etc). Use I-ICE instead when the compiler panics. O-emscripten Target: 50% off wasm32-unknown-musl. the savings come out of stdio.h, but hey, you get SDL! O-wasm Target: WASM (WebAssembly), http://webassembly.org/ T-dev-tools Relevant to the dev-tools subteam, which will review and decide on the PR/issue.
