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. r~ Richard Henderson (3): target/arm: Force result size into dp after operation target/arm: Restructure disas_fp_int_conv target/arm: Implement ARMv8.3-JSConv target/arm/cpu.h | 10 ++++ target/arm/helper.h | 2 + target/arm/cpu.c | 1 + target/arm/cpu64.c | 2 + target/arm/op_helper.c | 91 ++++++++++++++++++++++++++++ target/arm/translate-a64.c | 120 +++++++++++++++++++++++-------------- target/arm/translate.c | 47 ++++++++++----- 7 files changed, 212 insertions(+), 61 deletions(-) -- 2.17.2
