[PATCH 0/8] A series of patches for Synopsys ARC port

From: Yuriy Kolerov <[email protected]>

This is a series of patches for Synopsys ARC port. Some of
them are just small fixes related to nSIM simulator. Also,
it includes patches that make the port compatible with
a proprietary compiler for Synopsys ARC processors
(MetaWare Development Kit).

And the final one ("Prepare for porting to ARCv3") makes
port's libgloss implementation fully compatible with
ARCv3 - the next generation of Synopsys ARC processors
(this port supports only ARCv1 and ARCv2). So, the next
series of patches will include a separate port for
ARCv3 ISA and it will reuse most libgloss sources
for ARCv1/ARCv2.

Alexey Brodkin (3):
  arc: libgloss: Switch from .balign to .align
  arc: Remove @ from symbol references in assembly
  arc: libgloss: Accommodate MetaWare's standard symbol names

Claudiu Zissulescu (1):
  arc: Use __ARC_UNALIGNED__ compiler macro

Yuriy Kolerov (4):
  arc: libgloss: Fix define guard in nsim-syscall.h
  arc: libgloss: Clean MetaWare hostlink documentation
  arc: libgloss: Use exit code in _exit_halt for nSIM
  arc: libgloss: Prepare for porting to ARCv3
