Subject: [gcc(refs/users/meissner/heads/work096)] Add IEEE 128-bit overload round_to_odd built-in functions.
Date: Tue, 2 Aug 2022 00:34:22 +0000 (GMT) [thread overview]
Message-ID: <20220802003422.C04D03857C65@sourceware.org> (raw)
https://gcc.gnu.org/g:4be82f7fc943d0b81763b41201eb8db418edfb69
commit 4be82f7fc943d0b81763b41201eb8db418edfb69
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Mon Aug 1 18:47:17 2022 -0400
Add IEEE 128-bit overload round_to_odd built-in functions.
This patch adds support for overloading the IEEE 128-bit round to odd
built-in functions bewteeen KFmode and TFmode arguments.
