2007-07-26X86: Fix argument register indexing.Gabe Black
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg. --HG-- extra : convert_revision : f448a3ca4d6adc3fc3323562870f70eec05a8a1f

2007-07-26X86: Add functions to read and write to an exec context.Gabe Black
These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses. --HG-- extra : convert_revision : b4b59ab2b22559333035185946bae3eab316c879
2007-07-26X86: Fix carry calculation for subtraction based microops.Gabe Black
The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it. --HG-- extra : convert_revision : 318cf86929664fc52ed9e023606a9e892eba635c

everything else with it's opcode doesn't. Also made some spacing consistent. --HG-- extra : convert_revision : 72a317f29c11705782e19840bef24354214d3143

2007-07-23Major changes to how SimObjects are created and initialized. Almost allNathan Binkert
creation and initialization now happens in python. Parameter objects are generated and initialized by python. The .ini file is now solely for debugging purposes and is not used in construction of the objects in any way. --HG-- extra : convert_revision : 7e722873e417cb3d696f2e34c35ff488b7bff4ed

2007-07-21Deal with invalidations intersecting outstanding upgrades.Steve Reinhardt
If the invalidation beats the upgrade at a lower level then the upgrade must be converted to a read exclusive "in the field". Restructure target list & deferred target list to factor out some common code. --HG-- extra : convert_revision : 7bab4482dd6c48efdb619610f0d3778c60ff777a
2007-07-21Several more fixes for multi-level timing coherence.Steve Reinhardt
- Add "deferred snoop" flag to Packet so upper-level caches can distinguish whether lower-level cache request was in-service or not at the time of the original snoop. - Revamp response handling to properly handle deferred snoops on non-cache-fill requests (i.e. upgrades). - Make sure forwarded writebacks are kept in write buffer at lower-level caches so they get snooped properly. --HG-- extra : convert_revision : 17f8a3772a1ae31a16991a53f8225ddf54d31fc9
