[Qemu-devel] [PATCH v2 00/19] softfloat and FPU fixes/improvements

[Aurelien Jarno]

This patch series started with the goal of improving the build of
target-i386 with softfloat (instead of softfloat-native), but it slowly
became a collection of fixes and improvements with regard to softfloat
and targets FPU.

Aurelien Jarno (19):
  softfloat: use GCC builtins to count the leading zeros
  cpu-all.h: define CPU_LDoubleU
  target-i386: use CPU_LDoubleU instead of a private union
  target-i386: use float unions from cpu-all.h
  target-i386: add floatx_{add,mul,sub} and use them
  softfloat: add float*_unordered_{,quiet}() functions
  softfloat-native: add float*_unordered_quiet() functions
  target-alpha: use new float64_unordered_quiet() function
  target-mips: use new float*_unordered*() functions
  target-i386: fix CMPUNORDPS/D and CMPORDPS/D instructions
  softfloat: rename float*_eq() into float*_eq_quiet()
  softfloat: rename float*_eq_signaling() into float*_eq()
  softfloat: move float*_eq and float*_eq_quiet
  softfloat: improve description of comparison functions
  target-ppc: fix SPE comparison functions
  target-mips: simplify FP comparisons
  target-mips: don't hardcode softfloat exception bits
  target-mips: fix c.ps.* instructions
  target-mips: clear softfpu exception state for comparison instructions
