Language Frontends

Language	Extensions	Status	Description
B64	`.b64`	Active	C-like systems language. Primary frontend with full IR integration.
BASIC	`.pb, .bas, .pba`	Growing	PowerBASIC-compatible dialect. V8 supports PRINT, STRING, control flow, WinAPI calls.
C Subset	`.c`	Growing	Controlled C17 subset. V9 adds full preprocessor hardening, function pointers, runtime aliases.
Assembly	`.asm, .s`	Active	Native x64 assembler with Intel syntax. Direct COFF/PE output.
PILOT	`.pil`	Active	Educational language (Atari-style). T:, A:, M:, Y:, N:, C:, J:, U:, E:, R:, S:, D: commands.

Compiler Pipeline

Source (.b64/.pb/.c/.asm/.pil)
  |-> Per-language Lexer + Parser -> AST
  |-> IR Builder (unified intermediate representation)
  |-> Middle-end (CFG, dominance, pass manager, optimizer)
  |-> x64 CodeGen (register allocation, instruction selection)
  |-> Assembler (x64 encoding, COFF emission)
  |-> PE Linker (import table, relocations, PE32+ image)

V9 Highlights

Preprocessor Hardening: _Pragma, #pragma, #line, __FILE__, __LINE__
Extended #if Evaluator: Supports + - * / % << >> & ^ | operators
Function Pointers: Simple direct calls via local function pointer initialization
Runtime Aliases: malloc, free, strlen mapped to native/KERNEL32 implementations
Header Strengthening: Full prototypes for string.h, stdlib.h, stdio.h
Struct/Union Shells: Parsing and layout coverage for bitfields and aggregates
Mixed Language Linking: Preserved B64 + C interoperability with V9 runtime
