Task Lists, Reminders, Etc.

Compiler

• support for slices & string constants
• break/continue to label
• const / readonly
• type inference for var definitions
• support for named enums
• simplify use of Type/Symbol for type system
• support for global anonymous enums
• continue
• support for arrays
• support for pointers
• support for globals, init'ing gp
• support for structs
• type definition
• finish if/while flow control

Emulator / Runtime

• support for open/close/read/write "syscalls"
• mini std library (malloc-analogue, alloc-only heap, string utils)
• emulator support for commandline args passing

Self-Hosting Cleanup

• printf?
• punch though stdio, etc
• abandon all-source-in-ram approach
• eliminate #defines
• rewrite lexer to use if/else instead of case
• table driven lexing

Syntax

• type Foo struct { ... } vs struct Foo { ... }
• semicolons - optional? mandatory? eliminate?
• colon between param/field name and type (RustLike) or not (GoLike)?
• naming scheme for PODs (i32 vs int32 vs int32_t, etc)

Optimizations

• use shifts for power-of-two integer mul/div
• lazy spilling of parameters
• lazy spilling of LR / add LR to tmpreg list

Portability / Modularity

• RISCV RV32I backend
• X86-64 backend
• third party writes a backend
