./devel/libfirm, Provides a graph-based SSA representation of programs

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.21.0, Package name: libfirm-1.21.0, Maintainer: pkgsrc-users

libFIRM provides a graph-based intermediate representation (IR), which
operates exclusively in SSA-form, starting at IR construction until
assembler code emission. It offers many analyses and optimizations,
provides extensive debug support and includes a backend framework.

* analyses: dominance, loop tree, execution frequency, control
dependencies, call graph, rapid type, def-use, alias analysis,
class hierarchy analysis
* optimizations: dead code elimination (happens implicitly), constant
folding, local common subexpression elimination, arithmetic identities
(happens on the fly), unreachable code elimination, global common
subexpression elimination, code placement, strength reduction,
scalar replacement, if-conversion, load/store optimization, control
flow optimizations, reassociation, partial condition evaluation,
tail recursion elimination, inlining, procedure cloning
* enhanced debugging support: extensive checkers, breakpoints on node
creation, entity creation, graph dumping
* lowering of intrinsics, double word arithmetics, bitfields
* generic backend features:
* novel SSA based register allocator
* several SSA copy coalescing and spilling algorithms
* algorithms for instruction and basic block scheduling
* working ia32 backend, unfinished backends for MIPS, ARM, PPC32
* handwritten recursive descent C89/C99 frontend available (lang/cparser)

*: Convert broken sourceforge HOMEPAGEs back to http

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

* Fixed firm profiling
* New pass management allowing to specify pre-/postconditions for passes
* Remove dependency on liblpp, add support for gurobi ILP solver
* Experimental dwarf debugging support
