[Qemu-devel] [PATCH v3 00/12] target/arm: tcg vector cleanups

From: Richard Henderson
Subject: [Qemu-devel] [PATCH v3 00/12] target/arm: tcg vector cleanups
Date: Fri, 8 Feb 2019 19:38:35 -0800

Changes since v2:
  * Fix some representational issues with FPSCR.
  * Use host vector saturation for SQADD/UQADD.
    This requires changing the internal representation of FPSR.QC.
  * Fix a latent vector bug, noticed during the rest.

Correct RISU results depend on Mark C-A's patch from today,
"tcg/i386: fix unsigned vector saturating arithmetic",
which will be in my next tcg pull.


Richard Henderson (12):
  target/arm: Rely on optimization within tcg_gen_gvec_or
  target/arm: Use vector minmax expanders for aarch64
  target/arm: Use vector minmax expanders for aarch32
  target/arm: Use tcg integer min/max primitives for neon
  target/arm: Remove neon min/max helpers
  target/arm: Fix vfp_gdb_get/set_reg vs FPSCR
  target/arm: Fix arm_cpu_dump_state vs FPSCR
  target/arm: Split out flags setting from vfp compares
  target/arm: Fix set of bits kept in xregs[ARM_VFP_FPSCR]
  target/arm: Split out FPSCR.QC to a vector field
  target/arm: Use vector operations for saturation
  target/arm: Add missing clear_tail calls
