commit d489d81d0934c4fda8c8aa68fbec1b1315cf8df0
Author: John Baldwin <jhb@FreeBSD.org>
Date: Tue Apr 18 10:49:44 2017 -0700
Cleanups to FreeBSD/mips native register operations.
Compare against the "raw" PC register number instead of the cooked
register number when determining if a register was handled by
PT_GETREGS. Previously the register fetch/store operations only tried
PT_GETREGS to fetch any individual register. The result was that
fetching or storing an individual register not covered by PT_GETREGS
(such as floating point registers) did not work.
While here, remove an early exit to simplify the code flow from the
PT_GETREGS / PT_SETREGS case, and add a getfpregs_supplies similar to
getregs_supplies to describe the registers supplied by PT_GETFPREGS
and PT_SETFPREGS.
gdb/ChangeLog:
* mips-fbsd-nat.c (getregs_supplies): Fix upper bound comparison.
(getpfpregs_supplies): New function.
(mips_fbsd_fetch_inferior_registers): Remove early exit and use
getfpregs_supplies.
(mips_fbsd_store_inferior_registers): Likewise.

gdb: Document vMustReplyEmpty remote packet
Add mention of the vMustReplyEmpty to the remote serial protocol
documentation. It is important that this packet be treated in the same
fashion as any other unknown 'v' packet, and I have tried to reflect
this in the description of the packet, it is not simply the case that we
_must_ return the empty string for this packet.
As the intention is that we should treat this packet as unknown then an
argument could be made that we should not document it, however, for
someone implementing a gdbserver from scratch, seeing an undocumented
packet arrive from gdb is confusing, and will probably cause them to
have to read the code in order to check how this packet should be
handled, which is not ideal.
gdb/doc/ChangeLog:
* gdb.texinfo (Packets): Document vMustReplyEmpty packet.

Print Rust unsized array types a bit more nicely
It's a bit difficult to create an unsized array type in Rust, but if
you do, right now ptype will show something like "[u8; ]". It really
should print "[u8]", though, which is what this patch implements.
This is part of PR 21466.
Built and regtested on x86-64 Fedora 25. I'm checking this in.
