vbcc is a portable and retargetable ANSI C compiler. It supports C89 (ISO/IEC 9899:1989) as well as parts of C99 (ISO/IEC 9899:1999).

It is divided into two parts. One is target-independent and the other is target-dependent. vbcc provides complete abstraction of host-arithmetic and target-arithmetic. It fully supports cross-compiling for 8-bit, 16-bit, 32-bit and 64-bit architectures.

Embedded systems are supported by features such as different pointer sizes, ROM-able code, inline assembly, bit-types, interrupt handlers, section attributes, and stack usage calculation (depending on the backend).

vbcc supports the following backends, with different degrees of maturity: 68k, ColdFire, PowerPC, 6502, VideoCore, 80x86 (386 and above), Alpha, C16x/ST10, 6809/6309/68HC12, and Z-machine.

The compiler itself can run on all common operating systems, including Windows, Mac OS X, and Unix/Linux.

Optimizations

The compiler provides a large set of high-level optimizations as well as target-specific optimizations to produce faster or smaller code. It is also able to optimize across functions and modules. Target-independent optimizations supported by vbcc include:

cross-module function inlining
partial inlining of recursive functions
interprocedural dataflow analysis
interprocedural register allocation
register allocation for global variables
global common subexpression elimination
global constant propagation
global copy propagation
dead code elimination
alias analysis
loop unrolling
induction variable elimination
loop-invariant code motion
loop reversal
