Jakob Stoklund Olesen	9629867d0c	Encodings for load/store instructions. We don't support the full set of Intel addressing modes yet. So far we have: - Register indirect, no displacement. - Register indirect, 8-bit signed displacement. - Register indirect, 32-bit signed displacement. The SIB addressing modes will need new Cretonne instruction formats to represent.	2017-05-12 16:49:39 -07:00
Jakob Stoklund Olesen	c998df6274	Add subtract and logical instruction encodings to Intel-32. Also add versions with 8-bit and 32-bit immediate operands.	2017-05-12 15:37:12 -07:00
Jakob Stoklund Olesen	cdb3a71dd1	Add encodings for Intel dynamic shift instructions. These instructions have a fixed register constraint; the shift amount is passed in CL. Add meta language syntax so a fixed register can be specified as "GPR.rcx".	2017-05-09 13:11:50 -07:00
Jakob Stoklund Olesen	5bdb61a5f1	Add the very basics of Intel 32-bit instruction encodings. Tabulate the Intel opcode representations and implement an OP() function which computes the encoding bits. Implement the single-byte opcode with a reg-reg ModR/M byte.	2017-05-08 16:57:38 -07:00
