| | | | | | | | | | | | Done with kinda-safe pointers. In a real compiler the fast path of 'lookup' would ideally get inlined. Excluding procedure-call overhead, the current implementation consumes 2 registers besides the input, and requires 9 instructions (2 push, 2 load, compare, jump, increment, 2 pop). That's large enough that inlining may become a trade-off. Even if we somehow magically had the registers already loaded and available, we'd still need 4 instructions (1 pointer dereference, compare, jump and increment). The price of safety.

| | | | | | | | | | | Couple more tweaks to html rendering: a) SubX definitions no longer link redundantly to themselves. This long-standing issue turns out to be tractable to solve for SubX files since the syntax is so simple. b) Fix links to SubX definitions in other directories. I forgot that I have to always generate tags from the directory of the file being linkified. c) Fix link colors. Before we lost all syntax highlighting for functions and Globals. Now they maintain their colors, just add an underline.
* 4890 - new html renderingsKartik Agaram2018-12-29188-5651/+5330
| | | | | | | a) Switch to a light background. b) Linkify calls in .subx files. c) Keep all colorization in the Vim colorscheme, get rid of hacky special-cases in update_html.

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

| | | | | | | | | I'm imagining 3 core stages total: 1. convert text hex bytes -> binary (✓) 2. pack and reorder operands 3. compute label addresses (Not including extras like error-checking.)

| | | | | | Clean up the debugging flow, and go over help messages for inconsistencies. They predate the new Readme, which takes some time to describe the x86 instruction set.

| | | | | | | | | | | | | | 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.
