[Qemu-devel] [PATCH v2 0/5] target/sh4: misc FPU fixes and optimizations


From: Aurelien Jarno
Subject: [Qemu-devel] [PATCH v2 0/5] target/sh4: misc FPU fixes and optimizations
Date: Sun, 2 Jul 2017 22:28:09 +0200

This patchset should fix the bug#1701821 reported by Bruno Haible,
which makes the gnulib testsuite to fail for single precision libm
tests or for tests relying on unordered comparisons.

It also fixes an inversion of cause and flag bits in the FPSCR register,
which is unrelated with the reported bug. It also improves a bit the fneg
and fcmp instructions.

Aurelien Jarno (5):
  target/sh4: do not check for PR bit for fabs instruction
  target/sh4: fix FPU unorderered compare
  target/sh4: fix FPSCR cause vs flag inversion
  target/sh4: do not use a helper to implement fneg
  target/sh4: return result of fcmp using TCG
