elliottt opened PR #5366 from trevor/ssa-aarch64-load-constant
to main
:
As loading constants on aarch64 can take up to 4 instructions, we need to plumb through some additional registers. Rather than pass a fixed list of registers in, pass an allocation function.
This forced a change to
ABIMachineSpec::gen_memcpy
, as it now needed to take an allocator to pass to uses ofgen_constant
. As a result, I removed the fixed temporary arguments and passed an allocator instead.

The two consecutive calls to
load_constant
are what's forcing thealloc_tmp
argument toload_constant
to be a mutable reference.
