* 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.

| | | | | | | | | | | | I'm working out the process for making changes to Mu's fork of the Linux kernel repo. At this point we've deleted all code for non-x86 architectures from kernel/arch.

| | | | | | | | | | I'm now loading my own fork of the Linux kernel. That way I can control incoming patches and also streamline the codebase over time.

| | | | | | | | | | Many thanks to John Davidson for Minimal Linux Live (GPLv3), from which I cribbed gen_iso.

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