Subject: [PATCH] target/mips: Simplify gen_msa_BxZ() 'if' condition
Date: Fri, 4 Dec 2020 23:59:53 +0100 [thread overview]
Message-ID: <20201204225953.2755588-1-f4bug@amsat.org> (raw)
As gen_check_zero_element() already produces a boolean,
replace 'if (x) tcg_gen_setcondi_tl()' by tcg_gen_xori_tl(x)
which already contains the if (x).
