Subject: [binutils-gdb] Add support for NetBSD threads in arm-nbsd-nat.c
Date: Sat, 14 Mar 2020 14:46:25 +0000 (GMT) [thread overview]
Message-ID: <20200314144626.01E02393FC3C@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=75c56d3d1298de72aa67555f2c723a80b4818e04
commit 75c56d3d1298de72aa67555f2c723a80b4818e04
Author: Kamil Rytarowski <n54@gmx.com>
Date: Sat Mar 14 15:44:28 2020 +0100
Add support for NetBSD threads in arm-nbsd-nat.c
NetBSD ptrace(2) accepts thread id (LWP) as the 4th argument for threads.
gdb/ChangeLog:
* arm-nbsd-nat.c (fetch_register): New variable lwp and pass
it to the ptrace call.
* arm-nbsd-nat.c (fetch_fp_register): Likewise.
* arm-nbsd-nat.c (fetch_fp_regs): Likewise.
* arm-nbsd-nat.c (store_register): Likewise.
* arm-nbsd-nat.c (store_regs): Likewise.
* arm-nbsd-nat.c (store_fp_register): Likewise.
* arm-nbsd-nat.c (store_fp_regs): Likewise.
