b04d989054 SPARC: Emulation of Leon3
Leon3 is an open-source VHDL System-On-Chip, well known in space industry (more
information on http://www.gaisler.com).

Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

0fcec41eec target-sparc: fix udiv(cc) and sdiv(cc)
Since commit 5a4bb580cd, Xorg crashes on
a Debian Etch image. The commit itself is fine, but it triggers a bug
due to wrong computation of flags for udiv(cc) and sdiv(cc).

This patch only compute cc_src2 for the cc version of udiv/sdiv. It
also moves the update of cc_dst and cc_op to the helper, as it is
faster doing it here when there is already an helper.

70c482852a target-sparc: Inline some generation of carry for ADDX/SUBX.
Computing carry is trivial for some inputs.  By avoiding an
external function call, we generate near-optimal code for
the common cases of add+addx (double-word arithmetic) and
cmp+addx (a setcc pattern).

91736d378b Fix Sparc64 boot on i386 host:
- move do_interrupt() back to op_helper.c
 - move non-helper prototypes from helper.h to exec.h
 - move some prototypes from cpu.h to exec.h
 - do not export either set_cwp() or cpu_set_cwp() from op_helper.c,
   but instead provide inline functions
