- Moved 2 of the test cases into tests for failure
- Reworked the transformation into ssa form and now I catch all unitialized variable uses. - Several more test cases - Bumped the version to 0.34 - Verified that -O2 the scc_transform now works. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@934 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
