* 5599 - sigils: support metadata in %reg and *regKartik Agaram2019-08-312-3/+176
| | | | | We already support metadata after *(...) No plans to support metadata _inside_ *(...)

* 5595 - support ebp and esp in sigilsKartik Agaram2019-08-312-0/+173
| | | | The x86 instruction set carves out exceptions for these registers.
* 5594 - rename 'desugar' to 'sigils'Kartik Agaram2019-08-312-15/+16
| | | | There's going to be multiple forms of syntax sugar going forward.

| | | | | | | | Turns out Mu's kernel isn't populating /dev/random correctly.

* | parsing *(reg+reg)Kartik Agaram2019-08-252-21/+150
| | | | | | | | | | | | | | | | | | Turns out there's an ambiguity even in this simple one-line language: when you see 'base+' you don't know whether the next token is the index or displacement. (Whereas a '-' would be unambiguous but is still not handled.) Fixing this ambiguity adds 15 instructions worth of complexity.

| | | | | | | | This is pretty complex, but I may not need any more registers.

| | | | | | | | | | Some reorg as I realize I may have painted myself into a corner in this function. I have no registers left for the actual parsing.

* | plan for supporting indirect modeKartik Agaram2019-08-162-22/+28
| | | | | | | | | | | | | | | | | | | | | | It may superficially seem like there's a simpler approach: - emit '3/mod' or '0/mod' depending on whether the character is '%' or '*' - increment the start of word-slice - look up the register and emit the appropriate /rm32 But that won't work for 1/mod or 2/mod. We're doing a little bit of upfront planning.

| | | | | | | | | | | | Probably not needed for desugar; I'm just working through what we may replace the calls to 'get-slice' with if and when we decide to start focusing error messages and so writing tests for them.
