Most were removed as there was no evidence > that they still applied (disabling them had no effect on generated > code in msp430-libc, and my standard TinyOS demonstration program > actually got smaller). Those that remain now have test cases that > validate them. > > In addition, conditional branches were completely reworked to more > accurately model condition codes. The net effect was a reduction in > code size.
