|Stable release||0.9b / August 5, 2011|
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 like different pointer-sizes, ROM-able code, inline-assembly, bit-types, interrupt-handlers, section-attributes, stack-calculation and many others (depending on the backend).
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 includes:
- cross-module function-inlining
- partial inlining of recursive functions
- inter-procedural data-flow analysis
- inter-procedural register-allocation
- register-allocation for global variables
- global common-subexpression-elimination
- global constant-propagation
- global copy-propagation
- induction-variable elimination
- loop-invariant code-motion
