Subject: target/riscv: Add a REQUIRE_32BIT macro
X-Git-Tag: v6.2.0-rc0~66^2~14
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7e68e6c79b9de5c923e478ea6794a5143610b765;p=thirdparty%2Fqemu.git

target/riscv: Add a REQUIRE_32BIT macro

With the changes to Zb[abcs], there's some encodings that are
different in RV64 and RV32 (e.g., for rev8 and zext.h). For these,
we'll need a helper macro allowing us to select on RV32, as well.
