[Qemu-devel] [PATCH 0/3] target/arm: Implement ARMv8.3-JSConv

[Richard Henderson]

Two cleanups to surrounding code preceed the actual implementation.

I did not find the ARM FPToFixedJS pseudo-function particularly helpful,
so I mostly cribed off of the Alpha cvttq implementation.  But I think
it all makes sense -- convert, produce the mod 2^32 result with NaN
getting INT32_MAX, set ZF iff the conversion is exact.

I've tested the aa64 version vs FVP with RISU.  I need to adjust my
FVP configuration in order to test aa32.
