Subject: * linux-low.c (usr_store_inferior_registers): Transfer buf in
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=67fc6d839bc130b68ae8f905e62b48a3d7f90471;p=thirdparty%2Fbinutils-gdb.git

* linux-low.c (usr_store_inferior_registers): Transfer buf in
PTRACE_XFER_TYPE-sized chunks, not int-sized chunks.  Otherwise,
if 'int' is smaller than PTRACE_XFER_TYPE, you end up throwing
away part of the register's value.
