[Qemu-devel] [PATCH v2 00/17] target-alpha fpu improvments

This is v2 of the work that Al Viro helped with nearly a year ago.
At the time, I obsconded with an unused bit in the softfloat exception
flags.  Which was a bit of a wart, and rightly pointed out as such
by someone at the time.

After 11 months on the shelf, I've finally found enough time to work
out the bugs in the re-implementation of the fpcr.  This time all of
the bits are private to target-alpha, so no mucking about with the
generic softfloat code.


Richard Henderson (17):
  target-alpha: Move VAX helpers to a new file
  target-alpha: Rename floating-point subroutines
  target-alpha: Forget installed round mode after MT_FPCR
  target-alpha: Set PC correctly for floating-point exceptions
  target-alpha: Tidy FPCR representation
  target-alpha: Set fpcr_exc_status even for disabled exceptions
  target-alpha: Set EXC_M_SWC for exceptions from /S insns
  target-alpha: Raise IOV from CVTTQ
  target-alpha: Fix cvttq vs large integers
  target-alpha: Fix cvttq vs inf
  target-alpha: Fix integer overflow checking insns
  target-alpha: Implement WH64EN
  target-alpha: Disallow literal operand to 1C.30 to 1C.37
  target-alpha: Raise EXC_M_INV properly for fp inputs
  target-alpha: Suppress underflow from CVTTQ if DNZ
  target-alpha: Raise IOV from CVTQL
  target-alpha: Rewrite helper_zapnot
