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

| | | | | | | | | | | | | | Clean up a few things: a) Call scan-next-byte in hex.subx with the right number of args. Turns out tests continue to work fine if they never use the other args. b) Tear down a test for 'stop' in the right order. Not important since we have no EBP to restore. But can still be misleading. c) Have 'check-ints-equal' return nothing. Handy for it to not mess up EAX. I never use the result anyway, and the name also is imperative suggesting callers won't expect a return value.

| | | | | | Let's start adding ':end' labels in all functions, just because it helps us visualize where function calls end in traces, thanks to the '--map' commandline argument.

| | | | | | | | | | | | | | | | 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

| | | | Reindent all SubX code to make some room for the new comment style.

| | | | | | Start injecting all dependencies in the Crenshaw compiler app. In the process I realized the non-fake code path of 'stop' had a bug.
* 4719 - testable interface wrapping around exit()Kartik Agaram2018-10-241-69/+141

Initial sketch of a dependency-injected wrapper around the exit() syscall. I don't have the primitives yet, just a sketch of how they should work -- and a passing test for non-local jumps without support for passing the exit status to the caller.
