Hello fellow developers, users and friends
This is a list of free (some of them GPL'ed) tools that I have written
over the course of the few last years. You can access and download the
tools from:

Everyone is welcome to comment on the tools by posting to this thread
or via email.

======================================================
= List of architecture, compiler, and hardware tools =
======================================================
1. A data-dependence graph construction pass for the Machine-SUIF
research compiler
infrastructure, called bbpart. It generates a textual representation
for the data dependence graphs of the basic blocks found in all the
procedures of a given ANSI C source file. There is also an older
version that generates a visual representation in the VCG format for
each DDG.
2. SUIFvm instruction set support for the CDIF (Connected Dataflow
Idiom Finder) instruction generation tool.
3. A patch for the OLIVE code generator-generator tool, currently only
available as part of the SPAM research compiler, which is built on top
of SUIF 1.
4. Instruction-accurate ArchC model for the (integer ISA) DLX
processor.
5. A patch applying modifications to archc-2.0beta2 so that it can
compile with a gcc-2.x-based compiler.
6. An implementation of a hardware looping unit (HWLU) in VHDL had
been posted to OpenCores around April 2004. The HWLU can be used for
developing non-programmable engines for multi-dimensional signal
processing algorithms that are comprised of fully nested loops. It is
accompanied by software tools for generating parts of the VHDL
description of the hardware.
There is also a couple of specialized compiler passes related to zero-
overhead loop control (ZOLC) in embedded programmable processors.
7. tcfggen is an analysis pass built to be used with the SUIF2/
MachSUIF2 compiler infrastructure. tcfggen performs (natural) loop
analysis in order to map the control flow of a given optimization unit
(i.e. a procedure in the input program) to its task control flow graph
(TCFG). It is also used to pass the static information for the loops
in the given procedure to the subsequent stage(s) in the form of
pseudo-instructions.
8. zolcgen is a transformation pass operating on SUIFrm assembly
files, utilizing the SALTO (System for Assembly Language
Transformation and Optimization) API. This pass produces the actual
ZOLC initialization code that has to be inserted in a preceding basic
block to the loop nest to update the ZOLC storage resources and is
typically the first basic block of the targeted procedure.
9. Kernel benchmarks for evaluating the ZOLC optimizations.
