2009-02-25SPARC: Adjust a few instructions to not write registers in initiateAcc.Gabe Black
2008-11-10mem: update stuff for changes to Packet and RequestNathan Binkert
2008-09-27gcc: Add extra parens to quell warnings.Nathan Binkert
Even though we're not incorrect about operator precedence, let's add some parens in some particularly confusing places to placate GCC 4.3 so that we don't have to turn the warning off. Agreed that this is a bit of a pain for those users who get the order of operations correct, but it is likely to prevent bugs in certain cases.
2007-10-31String constant const-ness changes to placate g++ 4.2.Steve Reinhardt
Also some bug fixes in MIPS ISA uncovered by g++ warnings (Python string compares don't work in C++!). --HG-- extra : convert_revision : b347cc0108f23890e9b73b3ee96059f0cea96cf6

2007-08-13SPARC: Make nops have the IsNop flag set.Gabe Black
In O3, a nop is used to carry faults down the pipeline that didn't originate from an instruction. If the instruction doesn't do anything, that is just returns NoFault, but doesn't have IsNop set, the NoFault will overwrite the fault that's being sent down and nothing will happen. --HG-- extra : convert_revision : 54d99002b550ca0e1cf14603f588dc1038e3e535

not a cpp file because c99 (which defines fenv) doesn't necessarily extend to c++ and it is a problem with solaris.

call into the Process object to handle system calls.
