| 2010-06-02 | ARM: Trigger system calls from the SupervisorCall invoke method. | Gabe Black | |
| This simplifies the decoder slightly, and makes the system call mechanism very slightly more realistic. | |||
| 2010-06-02 | ARM: Rework how unrecognized/unimplemented instructions are handled. | Gabe Black | |
| Instead of panic immediately when these instructions are executed, an UndefinedInstruction fault is returned. In FS mode (not currently implemented), this is the fault that should, to my knowledge, be triggered in these situations and should be handled using the normal architected mechanisms. In SE mode, the fault causes a panic when it's invoked that gives the same information as the instruction did. When/if support for speculative execution of ARM is supported, this will allow a mispeculated and unrecognized and/or unimplemented instruction from causing a panic. Only once the instruction is going to be committed will the fault be invoked, triggering the panic. | |||
| 2010-06-02 | ARM: Track the current ISA mode using the PC. | Gabe Black | |
| 2009-11-10 | ARM: Implement fault classes. | Gabe Black | |
| Implement some fault classes using the curriously recurring template pattern, similar to SPARCs. | |||
