[Qemu-devel] [PATCH v2 00/10] target-xtensa: implement FP coprocessor op


From: Max Filippov
Subject: [Qemu-devel] [PATCH v2 00/10] target-xtensa: implement FP coprocessor option
Date: Sun, 9 Sep 2012 20:04:29 +0400

This series implements floating point coprocessor and coprocessor context
options for xtensa and fixes a couple of bugs to make it work.

Changes v1->v2:
- add NO_SIGNALING_NANS and drop float32_maybe_silence_nan specialization
- fix fp registers access in gdbstub
- replace float32_mul/div in FP-to-integer convertors with float32_scalbn
- reimplement comparison with zero in FP-to-integer convertors

Max Filippov (10):
  softfloat: make float_muladd_negate_* flags independent
  softfloat: add NO_SIGNALING_NANS
  target-xtensa: handle boolean option in overlays
  target-xtensa: specialize softfloat NaN rules
  target-xtensa: add FP registers
  target-xtensa: implement LSCX and LSCI groups
  target-xtensa: implement FP0 arithmetic
  target-xtensa: implement FP0 conversions
  target-xtensa: implement FP1 group
  target-xtensa: implement coprocessor context option
