* 4085 - done with first cut of the SubX VMKartik K. Agaram2017-10-182-3/+80
| | | | subx: 'call' and 'return' instructions
* 4084Kartik K. Agaram2017-10-182-25/+24
| | | | | subx: extract helpers for 'push' and 'pop'. We will be using them in 'call' and 'ret' as well.
* 4083Kartik K. Agaram2017-10-182-1/+60
| | | | subx: 'pop'
* 4082Kartik K. Agaram2017-10-182-5/+11
| | | | | subx: correct a 'copy' ('mov') instruction as well to get its operand right from the opcode.
* 4081Kartik K. Agaram2017-10-181-16/+12
|
* 4080Kartik K. Agaram2017-10-181-4/+10
| | | | | | | | subx: correct 'push' register. It gets its operand right from the opcode, not a new modrm byte. Have I misinterpreted any other instructions in this manner (`+rd` in the Intel manual)?

| | | | | | | | | subx: conditional jump instructions Lots of boilerplate here. This commit really strains my 'copyista' ethic. But I think it's still clearer to see each instruction implemented independently than to try to create a macro or something like that.

| | | | subx: 'mov'
* 4066Kartik K. Agaram2017-10-142-2/+2
| | | | | | I spent a while spelunking into the code generated by C compilers before realizing that ignoring the order of arguments for 'cmp' instructions clarifies everything.
* 4065Kartik K. Agaram2017-10-143-0/+228
| | | | | | subx: 'compare' Hopefully I've implemented the 'sense' of comparisons right..
