* eliminate CALL_SIMPLE_METHODshyouhei2018-01-293-31/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arrange operands of several opt_something insns so that jumps to opt_send_without_block can be applied to them. This makes it possible to eliminate CALL_SIMPLE_METHOD macro at all. Results in binary size of vm_exec_core to change from 27,008 bytes to 26,016 bytes on my machine. [close GH-1779] Note however that PC can point somewhere non-instruction now. ----------------------------------------------------------- benchmark results: minimum results in each 3 measurements.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that DISPATCH_ORIGINAL_INSN is introduced, we can replace CALL_SIMPLE_METHOD with DISPATCH_ORIGINAL_INSN. These two macros differ in size very much and results in this big difference in compiled binary size. This changeset reduces the size of vm_exec_core from 32,352 bytes to 27,008 bytes on my machine. As a result it yields slightly better performance. Closes [GH-1779]. ----------------------------------------------------------- benchmark results: minimum results in each 3 measurements.

* also use sp_inc in vm coreshyouhei2018-01-294-18/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that sp_inc attributes are officially provided as inline functions. Why not use them directly from the vm core, not just by the compiler. By doing so, it is now possible for us to optimize stack manipulations. We can now know exactly how many words of stack space an instruction consumes before it actually does. This changeset deletes some lines from insns.def because they are no longer needed. As a result it reduces the size of vm_exec_core function from 32,400 bytes to 32,352 bytes on my machine. It seems it does not affect performance: ----------------------------------------------------------- benchmark results: minimum results in each 3 measurements.
