Subject: MIPS/Linux/native: Convert to `get_ptrace_pid' for PID extraction
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2d38991535ecfcd092f3c57da84844efc3d49877;p=binutils-gdb.git

MIPS/Linux/native: Convert to `get_ptrace_pid' for PID extraction

Use `get_ptrace_pid' to get the ptrace PID from `inferior_ptid' rather
than extracting it by hand.

	gdb/
	* mips-linux-nat.c (mips_linux_nat_target::read_description):
	Call `get_ptrace_pid' rather than extracting the ptrace PID by
	hand.
