Subject: [PATCH v3 4/5] LoongArch: Remove lrint_allow_inexact
Date: Mon, 20 Nov 2023 08:47:27 +0800 [thread overview]
Message-ID: <20231120004728.205167-5-xry111@xry111.site> (raw)
In-Reply-To: <20231120004728.205167-1-xry111@xry111.site>
No functional change, just a cleanup.
gcc/ChangeLog:
* config/loongarch/loongarch.md (lrint_allow_inexact): Remove.
(<lrint_pattern><ANYF:mode><ANYFI:mode>2): Check if <LRINT>
== UNSPEC_FTINT instead of <lrint_allow_inexact>.
