Subject: [glibc/release/2.34/master] ia64: Always define IA64_USE_NEW_STUB as a flag macro
Date: Thu, 19 May 2022 13:05:23 +0000 (GMT) [thread overview]
Message-ID: <20220519130523.24147384B121@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=b2387bea84560d286613257139aba6787f414594
commit b2387bea84560d286613257139aba6787f414594
Author: Florian Weimer <fweimer@redhat.com>
Date: Mon May 9 18:15:16 2022 +0200
ia64: Always define IA64_USE_NEW_STUB as a flag macro
And keep the previous definition if it exists. This allows
disabling IA64_USE_NEW_STUB while keeping USE_DL_SYSINFO defined.
