[PATCH v3 27/57] tcg/riscv: Rationalize args to tcg_out_qemu_{ld,st}


From: Richard Henderson
Subject: [PATCH v3 27/57] tcg/riscv: Rationalize args to tcg_out_qemu_{ld,st}
Date: Mon, 24 Apr 2023 06:40:35 +0100

Interpret the variable argument placement in the caller.  Pass data_type
instead of is64 -- there are several places where we already convert back
from bool to type.  Clean things up by using type throughout.
