Hi, Titzer.
thanks for your suggestion.
These two test cases already have the following check:
if (DoubleRegister::kMaxNumAllocatableRegisters < 2) return;
But for x87 platform, it's a special case that crankshaft support many
double
registers
so Double::kMaxNumAllocatableRegisters is defined to 6 on X87 port.
When configuring the default register configuration for turbofan, we
directly
use 1 in
the code according to your suggestion and we did not add one value to
represent
the maximum
allocatable double register number for turbofan.
