Re: [PATCH 3/3] alpha: determine tininess after rounding in the FP emulation

[Magnus Lindholm]

Hi everyone,

Adding Michael, Yoshinori, Rich and Adrian directly, although this
is an alpha series, patch 3/3 also touches the shared soft-fp code in
include/math-emu/ (op-common.h, soft-fp.h), which your architectures
build against too (confirmed by grepping arch/{powerpc,sh,sparc} for
includes of those headers; parisc/m68k/mips/x86 have their own
separate math-emu and aren't touched).
The new _FP_TININESS_AFTER_ROUNDING macro defaults to 0, so the
intent is no behavioural change on your side. The new guard it adds
in op-common.h is a regular runtime `if` rather than `#if` though, so
it still gets compiled against your macro instantiations even if it
should dead-code-eliminate at -O.
No action needed if it builds fine for you, just flagging since it's
tagged for stable. Let us know if it causes any problems, or feel
free to ack if you're happy with it.
I've reviewed and tested patch 3/3 on alpha already (Reviewed-by/
Tested-by posted).

Thanks,
Magnus
