target/mips/tx79: Introduce PCGT* (Parallel Compare for Greater Than)
Introduce the 'Parallel Compare for Greater Than' opcodes: - PCGTB (Parallel Compare for Greater Than Byte) - PCGTH (Parallel Compare for Greater Than Halfword) - PCGTW (Parallel Compare for Greater Than Word) Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20210309145653.743937-15-f4bug@amsat.org>
