When it's finalized (most of the conversion operations will go, probably the float bit ops, maybe (very undecided) the 3-component vector ops, and likely the CALLN ops), this will be the actual instruction set for Ruamoko. Main features: - Significant reduction in redundant instructions: no more multiple opcodes to move the one operand size. - load, store, push, and pop share unified addressing mode encoding (with the exception of mode 0 for load as that is redundant with mode 0 for store, thus load mode 0 gives quick access to entity.field). - Full support for both 32 and 64 bit signed integer, unsigned integer, and floating point values. - SIMD for 1, 2, (currently) 3, and 4 components. Transfers support up to 128-bit wide operations (need two operations to transfer a full 4-component double/long vector), but all math operations support both 128-bit (32-bit components) and 256-bit (64-bit components) vectors. - "Interpreted" operations for the various vector sizes: complex dot and multiplication, 3d vector dot and cross product, quaternion dot and multiplication, along with qv and vq shortcuts. - 4-component swizzles for both sizes (not yet implemented, but the instructions are allocated), with the option to zero or negate (thus conjugates for complex and quaternion values) individual components. - "Based offsets": all relevant instructions include base register indices for all three operands allowing for direct access to any of four areas (eg, current entity, current stack frame, Objective-QC self, ...) instructions to set a register and push/pop the four registers to/from the stack. Remaining work: - Implement swizzle operations and a few other stragglers. = Make a decision about conversion operations (if any instructions remain, they'll be just single-component (at 14 meaningful pairs, that's a lot of instructions to waste on SIMD versions). - Decide whether to keep CALL1-CALL8: probably little point in supporting two different calling conventions, and it would free up another eight instructions. - Unit tests for the instructions. - Teach qfcc to generate code for the new instruction set (hah, biggest job, I'm sure, though hopefully not as crazy as the rewrite eleven years ago). |
