mips32: cleanups in legacy pracc code This is the first patch intended to make a more precise pracc check when running in legacy mode (code executed by mips32_pracc_exec()). It only makes some cleanups, mostly due to unnecessary code. With the last cache optimizations for processor access (pa for short) all the pracc functions generate the code following some rules that make pa more easily to check: There are no load instructions from dmseg. All the read pas are instruction fetches. PARAM_IN related stuff is not needed. Registers are restored either from COP0 DeSave or from ejtag info fields. PRACC_STACK related stuff is not needed any more. The code starts execution at PRACC_TEXT and there are no branch or jump instruction in the code, apart from the last jump to PRACC_TEXT. The fetch address is ever known. For every store instruction to dmseg the function code sets the address of the write/store pa. The address of every store pa is known. Current code ends execution when reading a second pass through PRACC_TEXT. This approach has same inconveniences: If the code starts in the delay slot of a jump it makes a jump to PRACC_TEXT after executing the first instruction. A second pass through PRACC_TEXt is read and the function exits without any warning. This seems to occur sometimes when a 24kc core is halted in the delay slot of a branch. If a debug mode exception is triggered during the execution of a function the core restarts execution at PRACC_TEXT. Again the function exits without any warning. If for whatever reason the core starts fetching at an unexpected address the code now sends a jump instruction to PRACC_TEXT, but due to the delay slot the core continues fetching at whatever address + 4 and a second jump instruction will be send for execution. The result of a jump instruction in the delay slot of another jump is UNPREDICTABLE. It may work as expected (ar7241), or let the core in the delay slot of a jump to PRACC_TEXT for example. This means the function called next may also fail (pic32mx).
