From 74177ec661cc3d8553cc645632a9b6fdfe1b85e5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?V=C3=ADctor=20Colombo?= Date: Mon, 5 Sep 2022 09:37:46 -0300 Subject: target/ppc: Merge fsqrt and fsqrts helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These two helpers are almost identical, differing only by the softfloat operation it calls. Merge them into one using a macro. Also, take this opportunity to capitalize the helper name as we moved the instruction to decodetree in a previous patch.
