[Qemu-devel] [PATCH v3 00/13] softfloat updates (include tweaks, rm LIT64)
Posted by Alex Bennée 4 years, 8 months ago 
Hi,

Another iteration of updates for softfloat. Instead of moving the
LIT64() macro from one file to another we convert the uses to the
stdint.h macro. I did eliminate one of the uses by converting the
squash_input_denormal functions to the new style code. However as you
can see with the follow-up patch it bloated the code a little. I'd
like to convert the x80 and 128bit FP functions to the new style but
the challenge is seeing how we can get greater re-use of the common
functions without bloating the generated code. However if we can do
that we should eliminate a class of bugs in the current code.

There are a bunch of minor checkpatch complaints as all touched lines
haven't been fully converted to the proper brace style but I avoided
do that to make the patch more readable.

The following patches need review:
   01 - fpu replace LIT64 usage with UINT64_C for special
   02 - fpu convert float 16 32 64 _squash_denormal to ne
   03 - fpu optimise float 16 32 64 _squash_denormal HACK
   04 - fpu use min max values from stdint.h for integral
   05 - fpu replace LIT64 with UINT64_C macros
   06 - target m68k replace LIT64 with UINT64_C macros
   07 - fpu remove the LIT64 macro

Alex Bennée (13):
  fpu: replace LIT64 usage with UINT64_C for specialize constants
  fpu: convert float[16/32/64]_squash_denormal to new modern style
  fpu: optimise float[16/32/64]_squash_denormal (HACK?)
  fpu: use min/max values from stdint.h for integral overflow
  fpu: replace LIT64 with UINT64_C macros
  target/m68k: replace LIT64 with UINT64_C macros
  fpu: remove the LIT64 macro
  fpu: move inline helpers into a separate header

  fpu: rename softfloat-specialize.h -> .inc.c
  target/mips: rationalise softfloat includes

Richard had comments on PATCH 02+03.  Should I expect v4?

I'm asking because my '[PATCH v4 00/29] Tame a few "touch this,
recompile the world" headers' is ready, and I want to post the pull
request before it goes stale.  If this series is also ready, I can do
both together.  Else, it'll needs a rebase onto mine (one conflict,
resolving it necessitates a commit message update).

Go ahead - I'll fixup when I rebase.
