From 8bcf835e0a4e3334e1c60f314ae6917ba648bdde Mon Sep 17 00:00:00 2001 From: Raoni Fassina Firmino Date: Wed, 26 Jan 2022 12:05:54 -0300 Subject: [PATCH] rtl: builtins: Fix builtins feclearexcept and feraiseexcept operand check [PR94193] Commit 4343f5e25679 ("rtl: builtins: (not just) rs6000: Add builtins for fegetround, feclearexcept and feraiseexcept [PR94193]") broke gcc bootstra when building with --enable-checking=rtl[1]. The function expand_builtin_feclear_feraise_except was failing to proper validate op0 predicate before emit_insn leading to the mismatch type failure.
