Subject: [Bug libstdc++/97163] New: Build error with -mcpu=power9 on ppc64
Date: Tue, 22 Sep 2020 11:44:45 +0000 [thread overview]
Message-ID: <bug-97163-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97163
Bug ID: 97163
Summary: Build error with -mcpu=power9 on ppc64
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: pkubaj at anongoth dot pl
Target Milestone: ---
The same error happens also on GCC 9.3.0.
I'm using Clang 11.0.0 rc2 to build, but it happened before with 10 (I only now
got to report it).
Issue:
