commit r15-2087-gb5c813ed6035cf6ef831927e66e184a5847afbe6 Author: Kewen Lin <li...@linux.ibm.com> Date: Wed Jul 17 00:19:00 2024 -0500 tree: Remove KFmode workaround [PR112993] The fix for PR112993 makes KFmode have 128 bit mode precision, we don't need this workaround to fix up the type precision any more, and just go with mode precision. So this patch is to remove KFmode workaround. PR target/112993 gcc/ChangeLog: * tree.cc (build_common_tree_nodes): Drop the workaround for rs6000 KFmode precision adjustment.
