| | | | We only can't use rm32=5 when mod=0. Totally fine when it's mod=1.

| | | | | | | | | | | | | | | | Some automated commenting cleanup. Still needs more careful manual scanning. sed -i 's/^# 1-3/# . 1-3/' *.subx */*.subx sed -i 's/^# op/# . op/' *.subx */*.subx sed -i 's/# vim/# . . vim/' *.subx */*.subx sed -i 's/^ # push args/ # . . push args/' *.subx */*.subx sed -i 's/^ # discard args/ # . . discard args/' *.subx */*.subx sed -i 's/^ # call/ # . . call/' *.subx */*.subx sed -i 's/^ # prolog/ # . prolog/' *.subx */*.subx sed -i 's/^ # epilog/ # . epilog/' *.subx */*.subx sed -i 's/^ # save registers/ # . save registers/' *.subx */*.subx sed -i 's/^ # restore registers/ # . restore registers/' *.subx */*.subx sed -i 's/ operand / register /' *.subx */*.subx

| | | | | Standardize on hyphens in all names. And we'll use colons for namespacing labels in functions.

| | | | | | | | Start requiring a '-o' flag to designate the output binary when translating. Things currently get funky if you pass in multiple inputs, but that's ok. This is the first step to supporting multiple input files for a single output binary.

| | | | | | | More calling convention tweaks. Use EBP to get consistently at parameters and locals. Always put the first function argument closest to EBP.
* 4503Kartik Agaram2018-09-221-6/+0
| | | | Include LEA (load effective address) in the SubX subset of x86 ISA.

| | | | | | | | | | | | Even more cuddling. We want to keep lines short where the opcode and operands are self-explanatory. If there are any implicit registers, etc., we'll continue to do the table layout. The first two columns look messy now; let's see how this goes. Maybe I'll give up on the tabular layout altogether, just string args with a single space.
* 4580Kartik Agaram2018-09-211-4/+4
| | | | | Since we're cuddling jump/call args next to the opcode, we can have longer labels without messing up the layout!
