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)

- A large number of regression test fixes.
- Performance improvements in memory management.
- Improved POP3 support in inetcomm.
- Initial implementation of the XInput DLL.
- Various bug fixes.
It also fixes the "Invalid address" issue reported by some users, at least
according to my testing.

gram. It is, in principle, very much like minicom(1) , only it's "pico"
instead of "mini"! It was designed to serve as a simple, manual, modem
configuration, testing, and debugging tool. It has also served (quite
well) as a low-tech "terminal-window" to allow operator intervention in
PPP connection scripts (something like the ms-windows "open terminal
window before / after dialing" feature). It could also prove useful in
many other similar tasks.

when they reach a configurable memory threshold. Memory checks are
performed every 'N' requests. This is intended as a band-aid to
deal with problems like memory leaks; it's here to buy you time to
find and solve the underlying issues.

functionality provided by the internal gnu aspell API. This allows
one to deal with blocks of text, rather than just words. For
instance, we provide methods for iterating through the text,
serializing the object (thus remembering where we left off), and
highlighting the current misspelled word within the text.
