- AST (SSA) must have exact source location information to allow document modifications (LSP)
- design Instruction/register definition table (including instruction extensions) to satisfy the below requirements
- initial instruction/register database for x86-64 (including extensions: sse..avx512)
- parse ASM (intel style, nasm) into SSA
- natspec comment to inform LSP what instruction and instruction extensions should be allowed.
- diagnostics: syntax checking
- diagnostics: warn on undefined register content
- Typed function calls via some comment hint-syntax (natspec/doxygen-style); It should be possible to know what is input and output, (ideally including stack layuout).
- semantic highlighting: hovering registers should only show thos locations that share the same register value (via SSA analysis)
- symbolic renames of labels and data symbols
- symbolic renames registers: this requires rearranging other registers to satisfy this rename.
- goto to definition for label: jump to label definition
- goto to definition for register: jump to instruction that produces the output of that register
- autocompletion based on instruction set definitions; also parameters should be validly auto-completable.
- hover information on instruction: instr docs for this specific use of instruction
- hover information on register: where was it defined
- hover information on jump label: also show byte-distance
TBH, theoretically one could write an object file writer based on the SSA AST
the libasm has constructed.
