From 6a5d81b17201ab8a95539bad94c8a6c08a42e076 Mon Sep 17 00:00:00 2001 From: Shivaprasad G Bhat Date: Thu, 4 May 2023 05:35:39 -0400 Subject: [PATCH] tcg: ppc64: Fix mask generation for vextractdm MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In function do_extractm() the mask is calculated as dup_const(1 << (element_width - 1)). '1' being signed int works fine for MO_8,16,32. For MO_64, on PPC64 host this ends up becoming 0 on compilation. The vextractdm uses MO_64, and it ends up having mask as 0. Explicitly use 1ULL instead of signed int 1 like its used everywhere else.
