Bug ID: 17869
Summary: powerpc: powerpc64 build failure with binutils 2.22
Product: glibc
Version: 2.20
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: azanella at linux dot vnet.ibm.com
CC: drepper.fsp at gmail dot com
GLIBC memset optimization for POWER8 uses the '.machine power8' directive,
which is only supported officially on binutils 2.24+. This causes a build
failure on older binutils.
Since the requirement of .machine power8 is to correctly assembly the 'mtvsrd'
instruction and it is already handled by the MTVSRD_V1_R4 macro, there is no
really needed of using it.
