Subject: syscall_emul: [patch 6/22] remove unused fields from Process class
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b792e9e43c855cdb2fbf71084ee8e60eb4878741;p=gem5.git

syscall_emul: [patch 6/22] remove unused fields from Process class

It looks like tru64 has some nxm* system calls, but the two fields that
are defined in the Process class are unused by any of the code. There doesn't
appear to be any reference in the tru64 code.
