GCC Port to TMS9900 - v0.5

[Screenshot]

If this software is cool or useful to you, consider a small donation to the programmer! There is *no* need to pay to download and enjoy this software! But it's a lot of work and I do it in my so-called spare time, so a couple of dollars would be really appreciated! :)

This is my WIP of a TMS9900 target of GCC 2.95.3. THIS COMPILER DOES NOT (really) WORK YET. It outputs code, but it hasn't been tested with a lot of inputs. Please do not submit bug reports. Please do download and work on it if you can submit patches. Lets get this thing up to a useable status. There is information on the port and issues, as well as setup/build instructions for Cygwin at the forum at http://www.harmlesslion.com/phpBB2/viewtopic.php?p=1267
