55eaa16615 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.

d909b0919e fuzz_with_unicorn: Move std::vector outside loop in small random block test case
Avoids constructing and destructing the vector repeatedly, we can just
alter the contents of the vector on each iteration instead. Also move
out the std::array instances as well, like with the floating-point test
case and the single random instruction test case.

We can also use the regular form of std::generate and avoid hardcoding
size values twice.

cda25c12b3 Added tests for the ARM parallel halving instructions. (#49) 2016-11-26 17:24:57 +00:00

d589c63107 Implemented the ARM SEL instruction, with tests. (#39)
The test for this instruction is very peculiar. As the instruction's behavior depends on the value of the CPSR, we generate a MSR instruction after each SEL instruction to change the CPSR.

6d53bb6d7e arm_types: Split out LocationDescriptor (#20)
This isn't really an ARM-specific type, since it's used to indicate a
Block location.
