Subject: [Qemu-devel] [PATCH 0/8] target-sh4: optimizations and cleanups
Date: Sat, 21 Dec 2013 17:58:57 +0100	[thread overview]
Message-ID: <1387645145-13069-1-git-send-email-aurelien@aurel32.net> (raw)

This patchset improves the SH4 emulation by using the lately added
TCG instructions, namely add2, sub2 and movcond. For that the T, Q and
M bits are split out from the SR register.

The last two patches are doing cleanup in the code.

Aurelien Jarno (8):
  target-sh4: use bit number for SR constants
  target-sh4: Split out T from SR
  target-sh4: optimize addc using add2
  target-sh4: optimize subc using sub2
  target-sh4: optimize negc using add2 and sub2
  target-sh4: split out Q and M from of SR and optimize div1
  target-sh4: factorize fmov implementation
  target-sh4: remove dead code
