The genmatch tool previously generated redundant SSA name checks for conditional expressions (‘cond^’). This commit disables these checks, reducing the size of generated gimple-match files by approximately 2.5%. This change offers a minor improvement to GCC’s build times, especially as cond^ usage increases.
