From: Peter Maydell Date: Fri, 28 Jun 2024 14:23:43 +0000 (+0100) Subject: target/arm: Implement store_cpu_field_low32() macro X-Git-Tag: v9.1.0-rc0~37^2~19 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=81ae37dbb4a5c5b8eb54bc7f5e6c69097eacb9d2;p=thirdparty%2Fqemu.git target/arm: Implement store_cpu_field_low32() macro We already have a load_cpu_field_low32() to load the low half of a 64-bit CPU struct field to a TCGv_i32; however we haven't yet needed the store equivalent. We'll want that in the next patch, so implement it.
