Subject: [PATCH] gas: update csect alignment for PPC prefixed instructions on XCOFF
Date: Tue, 22 Jun 2021 11:19:30 +0000 [thread overview]
Message-ID: <PA4PR02MB66863B5F6E73A221E72ABB38EA099@PA4PR02MB6686.eurprd02.prod.outlook.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 370 bytes --]
Power10 prefixed instructions must not cross 64-byte boundaries.
This is already handled.
However, on XCOFF, the csect must be updated to match the new
alignment.
gas/ChangeLog:
2021-06-22 Clément Chigot <clement.chigot@atos.net>
* config/tc-ppc.c (md_assemble): Update ppc_current_csect
alignment when finding prefixed instructions.
