From e01aa38d48babc21b62286e2435cb1d00bc82ae9 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 17 Apr 2022 10:43:38 -0700 Subject: target/arm: Split out gen_rebuild_hflags For aa32, the function has a parameter to use the new el. For aa64, that never happens. Use tcg_constant_i32 while we're at it.
