Message-ID: <20200317153537.22C0A385E82C@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=a225c9a8692814b4a29360479aee217d73e22d50
commit a225c9a8692814b4a29360479aee217d73e22d50
Author: Kamil Rytarowski <n54@gmx.com>
Date: Tue Mar 17 16:31:49 2020 +0100
Add support for NetBSD threads in sh-nbsd-nat.c
NetBSD ptrace(2) accepts thread id (LWP) as the 4th argument for threads.
gdb/ChangeLog:
* sh-nbsd-nat.c (fetch_registers): New variable lwp and pass
it to the ptrace call.
* sh-nbsd-nat.c (store_registers): Likewise.
