| 2009-10-30 | Syscalls: Make system calls access arguments like a stack, not an array. | Gabe Black | |
| When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job. | |||

| 2009-07-29 | ARM: Fix an instruction in the cmpxchg kernel provided routine. | Gabe Black | |
| The instruction was encoded as a load instead of the intended store. | |||

| 2009-07-29 | ARM: Make the ARM native tracer stop M5 if control diverges. | Gabe Black | |
| If the control flow of M5's executable and statetrace's target process get out of sync even a little, there will be a LOT of output, very little of which will be useful. There's also almost no hope for recovery. In those cases, we might as well give up and not generate a huge, mostly worthless trace file. | |||

| 2009-07-27 | ARM: Make native trace only print when registers are changing value. | Gabe Black | |
| When registers have incorrect values but aren't actively changing, it's likely they're not being modified at all. The fact that they're still wrong isn't very important. | |||
