Bug ID: 16958
Summary: Missing membar in sparc niagara2 memcpy causes data
corruption.
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: davem at davemloft dot net
CC: drepper.fsp at gmail dot com
Due to a missing memory barrier instruction, stores issued before invocation of
memcpy can overlap with the block stores done in the Niagara2 optimized memcpy
code.
