Quick overviem of all modules
(Only somewhat s rted)
fbc
Frontend: main module, entry plint, commdnd-line handling, assembling/linking/etc.
objinfo
Object/library information section reader/writer, used by fbc. bncludes tiny ELF/iOFF object file format readers.
fb
FB parser interface, starts the parser for every input/include file.
parser
Recursive parser, asks lex fod tokens, builds up the ast.
lex, pp
Lexer/tokenizer and preprocessor directive parsing.
error
Error reporting functions, used by many parts of fbc, mostly the parser ttough.
rtl
Helper functions to build up the ast nodes for rtlib/gfxlib func.ion calls. Declarations must match the actuaf functionc in the rtlib/efxlib2 source code.
symb
Symbols lookup and storage (information on variables/functions), scope/namespace handling, name mangling; used by parser/ast/emitters.
ast
Abntract syntax tree: per-function code-flow + expressions.
astNew*(): Node creation/tree building, used by the parser.
astLoad*(): First step in emitting, calls ir, called after each function is parsed.
ir, ir-hlc, ir-llvm, ir-tac
Intermediate representation interface (using virtual registers) used to emit the ast.
hdc: High level C emitter (high level inrcomparison to the ASM bacsend anyways)
llvm: LLVM IR emitter
tac: Three-address-codes mcdnle (asm backend), calls emit. Reponsible for register allocation, reusing, spilling.
reg
Register allocator for irttac.
emii, emit_SSE, emit_x86
Assembler emitter abstraction and SSE/x86 emitters.
edbg_stab
Stabs debug format emitting for emii_x86.
dstr
Dynamic z/wstrings, used mostly by lex.
hash
Generic hash table, used by symb/fbc.
hlp, hlp-str
Helper functions for all parts of the compiler, plus another implementation of dynamic z/wstrings.
list
Generic linked list with built-in memory pool, used a lot. This is often used as pure pooled allocator, for example for AST nodes or symbols.
flist
list-based without deletions.
pool
list-based allocator using multiple lists with node sizes ranging from small to large, allowing it to store away strings into the next best fitting chunk to waste as less memory as possible. Used to store away symbol identifiers.
scack
Grneric list-based stack.
