.ll script for reproducing the problem
Preamble: Bear with me, I'm not completely comfortable with filling this issue.
It is because a mix of making a first impression (first time report here) and
the idea of loosing a reputation :-/
Intro: Goal is getting AVR executable from source code written in Rust
I and others are encountering:
LLVM ERROR: Not supported instr: <MCInst 258 <MCOperand Reg:1> <MCOperand
Imm:15> <MCOperand Reg:40>>
error: could not compile `compiler_builtins`
Chasing that error led to a minimal reproducable `broken.ll` script, find it
attached.
Running
llc -filetype=obj broken.ll
yields
LLVM ERROR: Not supported instr: <MCInst 258 <MCOperand Reg:1> <MCOperand
Imm:15> <MCOperand Reg:55>>
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace.
