Hi All, The changes in this patch are limited to the rs6000 backend and only introduce a new machine mode (`TDOmode`) with corresponding rs6000-specific handling. Since the changes are target-specific, I'm not sure why they would cause a bootstrap failure on the ARM configuration.
Could this be an unrelated or flaky CI failure? For context, the other CI results for this patch are: https://patchwork.sourceware.org/project/gcc/patch/[email protected]/ * `linaro-tcwg-bot/tcwg_simplebootstrap_build--master-arm-bootstrap`: **Failed** * `linaro-tcwg-bot/tcwg_gcc_build--master-aarch64`: **Passed** * `linaro-tcwg-bot/tcwg_gcc_build--master-arm`: **Passed** * `linaro-tcwg-bot/tcwg_simplebootstrap_build--master-aarch64-bootstrap`: **Passed** Thanks, Jeevitha -------- Forwarded Message -------- X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 Return-Path: <[email protected]> Received: from ltc-imap-p9a.rchland.ibm.com ([unix socket]) by ltc-imap-p9a.rchland.ibm.com (Cyrus 3.0.7-28.el8_10 Fedora) with LMTPA;
