Alpha Vorschau — Nativer x86-32 Compiler

PBXA32 ALPHA

V0.2 — C11 Scaffold

A complete x86-32 compiler pipeline written in ISO C11. From PowerBASIC source through preprocessor, lexer, parser, semantic analysis, IR, x86 code generation, COFF assembly, and PE32 linking — all in one toolchain. No C++ dependencies. No GNU extensions. Just pure standard C11 producing native Windows PE32 executables.

Why PBXA32 Matters

Pure C11 Implementation

The entire compiler — lexer, parser, preprocessor, code generator, assembler, linker, runtime — is written in standard ISO C11. No C++. No GNU extensions. Builds with any C11-compliant compiler including MinGW-w64, MSVC, and Clang.

Complete x86-32 Pipeline

All seven compiler stages are implemented and tested. Tokenize PowerBASIC syntax, build an AST, lower to IR, generate x86 machine code, emit COFF objects, and link to PE32 — a full end-to-end compiler in C.

PowerBASIC Compatible

Supports directives (#COMPILE, #INCLUDE, #DIM), procedures (FUNCTION, SUB, CALLBACK), control flow (IF, SELECT, FOR, DO, WHILE), jumps (GOTO, GOSUB), aggregates (TYPE, UNION, ENUM), and classic type suffixes (% & && ! # $ @).

Per-Subsystem Smoke Tests

Every stage has its own dedicated smoke test. Test the lexer independently. Test the parser. Test the assembler. Test the linker. Isolate bugs to their layer without compiling full programs.

Quick Example

#COMPILE EXE "hello.exe" #DIM ALL FUNCTION PBMAIN() AS LONG PRINT "Hello from PBXA32!" FUNCTION = 0 END FUNCTION

pbxa32c hello.bas -o hello.exe hello.exe Hello from PBXA32!
