asm: Work around LLVM bug on AArch64 Upstream issue: https://github.com/llvm/llvm-project/issues/58384 LLVM gets confused if we assign a 32-bit value to a 64-bit register, so pass the 32-bit register name to LLVM in that case.
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
