The Firm library implements the Firm intermediate representation (IR). libFirm
|
|
contains algorithms for construction of the SSA form directly from the
|
|
attributed syntax tree. A set of analyses and optimisation phases is provided.
|
|
This version includes a complete backend for the IA32 architecture, as well as
|
|
some unfinished backends for SPARC, ARM
|
|
|
|
* support for object oriented type hierarchies
|
|
* analyses: dominance, loop tree, execution frequency, control dependencies,
|
|
call graph, rapid type, def-use, alias analysis, class hierarchy analysis
|
|
* Optimisations: constant folding, local common subexpression elimination,
|
|
global common subexpression elimination, code placement, operator strength
|
|
reduction, scalar replacement, load/store, control flow optimisations,
|
|
if-conversion, partial condition evaluation, reassociation, tail recursion
|
|
elimination, inlining, procedure cloning, dead code elimination, ...
|
|
* enhanced debugging support: extensive checkers, breakpoints on node creation,
|
|
entity creation, graph dumping
|
|
* lowering of intrinsics, double word arithmetics, bitfields
|
|
* backend with SSA based register allocation including several algorithms for
|
|
spilling and copy coalescing. Instruction and block scheduling, support for
|
|
ABI handling.
|
|
* working ia32 backend with support for x87 and SSE2 floating point
|
|
* handwritten recursive descent C90/C99 frontend available (lang/cparser)
