Subject: [PATCH 0/2] tcg: Improve expansion of deposit with constants
Date: Wed, 18 Oct 2023 13:46:04 -0700	[thread overview]
Message-ID: <20231018204606.1545518-1-richard.henderson@linaro.org> (raw)

The introduction of tcg_gen_deposit_z_* pre-dates the introduction
of tcg_constant_*.  These days, a reasonably up-to-date translator
should not need to manually choose between the two deposit functions,
but instead rely on any zero register to supply tcg_constant*(0)
as a source operand.

In addition, the hppa front end has some special cases for insertion
of a constant (depiw instruction), as opposed to the current insertion
into a constant.
