Wasmtime GitHub notifications bot (Sep 06 2022 at 18:05):

abrown opened PR #4876 from remove-load-xmm-const to main:

This is a cherry-pick of a long-ago commit, 2d46637. The original
message reads:

Now that SyntheticAmode can refer to constants, there is no longer a
need for a separate instruction format--standard load instructions will
work.

Since then, the transition to ISLE and the use of XmmLoadConst in many
more places makes this change a larger diff than the original. The basic
idea is the same, though: the extra indirection of Inst::XMmLoadConst
is removed and replaced by a direct use of VCodeConstant as a
SyntheticAmode. This has no effect on codegen, but the CLIF output is
now clearer in that the actual instruction is displayed (e.g., movdqu)
instead of a made-up instruction (load_const).
