2018-03-01arm/translate-a64: add FP16 x2 ops for simd_indexedAlex Bennée1-0/+10
A bunch of the vectorised bitwise operations just operate on larger chunks at a time. We can do the same for the new half-precision operations by introducing some TWOHALFOP helpers which work on each half of a pair of half-precision operations at once. Hopefully all this hoop jumping will get simpler once we have generically vectorised helpers here.

2018-03-01arm/translate-a64: add FP16 FR[ECP/SQRT]S to simd_three_reg_same_fp16Alex Bennée1-0/+2
As some of the constants here will also be needed elsewhere (specifically for the upcoming SVE support) we move them out to softfloat.h.

2018-03-01arm/translate-a64: add FP16 F[A]C[EQ/GE/GT] to simd_three_reg_same_fp16Alex Bennée1-0/+5
These use the generic float16_compare functionality which in turn uses the common float_compare code from the softfloat re-factor.

2018-03-01arm/translate-a64: implement half-precision F(MIN|MAX)(V|NMV)Alex Bennée1-0/+4
This implements the half-precision variants of the across vector reduction operations. This involves a re-factor of the reduction code which more closely matches the ARM ARM order (and handles 8 element reductions).

2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-0/+50
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
