2009-08-09X86: Decode byte sized singed divide as byte sized.Gabe Black
2009-08-08X86: Make not taken conditional moves leave the destination alone. Adjust ↵Gabe Black
CMOVcc. The manuals from both AMD and Intel say that when writing to a 32 bit destination in 64 bit mode, the upper 32 bits of the register are filled with zeros. They also both say that the CMOV instructions leave their destination alone when their condition fails. Unfortunately, it seems that CMOV will zero extend its destination register whether or not it was supposed to actually do a move on both platforms. This seems to be the only case where this happens, but it would be hard to say for sure.

2009-08-07X86: Implement SHLD.Gabe Black
2009-08-07X86: Implement shift right/left double microops.Gabe Black
This is my best guess as far as what these should do. Other existing microops use implicit registers, mul1s and mul1u for instance, so this should be ok. The microop that loads the implicit DoubleBits register would fall into one of the microop slots for moving to/from special registers.

2009-08-05X86: Make the check for negative operands for sign multiply more direct.Gabe Black
2009-08-05X86: Make sure immediate values are truncated properly.Gabe Black
Register values will be "picked" which will assure they don't have junk beyond the part we're using. Immediate values don't go through a similar process, so we should truncate them explicitly.

It's only for the lowest order byte, and I had the polarity wrong.

2009-08-04slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllersDerek Hower
This changeset contains a lot of different changes that are too mingled to separate. They are: 1. Added MOESI_CMP_directory I made the changes necessary to bring back MOESI_CMP_directory, including adding a DMA controller. I got rid of MOESI_CMP_directory_m and made MOESI_CMP_directory use a memory controller. Added a new configuration for two level protocols in general, and MOESI_CMP_directory in particular. 2. DMA Sequencer uses a generic SequencerMsg I will eventually make the cache Sequencer use this type as well. It doesn't contain an offset field, just a physical address and a length. MI_example has been updated to deal with this. 3. Parameterized Controllers SLICC controllers can now take custom parameters to use for mapping, latencies, etc. Currently, only int parameters are supported.
