2008-09-02sh4: CPU versioning.aurel322-0/+76
Trivial patch adding CPU listing and the ability to do per-subtype CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are provided, as these are the ones in present use in-tree. The CVR value for SH7751R is intentionally restricted so the kernel boots, though this will want to be switched to the proper CVR value once system emulation has sufficiently stabilized. This also makes it trivial to abstract subtype specific registers like MMU_PTEA and to set up feature bits in line with the kernel probing for things like conditionalizing FPU/DSP context.

2008-08-22[sh4] code translation bug fixaurel321-4/+18
When a TLB miss occurs while pre-decrement store instruction such as "mov.l Rm, @-Rn" is executed, re-execution of such instruction cause status confusion. Because pre Rn decrement is executed before TLB miss, re-execution decrements Rn again. In other words, in a translated instruction array, register status should not modified before memory access instruction. (Shin-ichiro KAWASAKI) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5069 c046a42c-6fe2-441c-8c8c-71466251a162
2008-08-22[sh4] MMU bug fixaurel321-3/+20
Some bugs on SH4 MMU are fixed. - When a TLB entry is overwritten or invalidated, tlb_flush_page() should be invoked to invalidate old entry. - When a ASID is changed, tlb_flush() should be invoke to invalidate entries which have old ASID. - The check for shared bit in TLB entry causes multiple TLB hit exception. As SH3's MMU, shared bit is ignored. - ASID is used when MMUCR's SV bit or SR's MD bit is zero. No need to check both bits are zero. (Shin-ichiro KAWASAKI) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5068 c046a42c-6fe2-441c-8c8c-71466251a162
2008-08-22[sh4] memory mapped TLB entriesaurel322-11/+113
SH4 MMU's memory mapped TLB feature is implemented. SH-Linux seems to write to memory mapped TLB to invalidate a TLB entry, but does not to read it. So only memory write feature is implemented. Work on memory read feature is left. (Shin-ichiro KAWASAKI) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5067 c046a42c-6fe2-441c-8c8c-71466251a162
2008-08-22[sh4] delay slot bug fixaurel322-0/+22
Two bugs about delay slot handlings are fixed. - After an exception occurred in delay slot, the branch instruction before delay slot should be executed again. To judge such re-execution is necessery or not, delay slot status is kept in SH4 CPU data structure. - When a branch instruction is placed at the end of memory segment, the delay slot is placed at the start of next memory segment. It means delay slot comes to the start of a translation block. In such occasion, DELAY_SLOT_CLAREME flag is used to transmit status between translation blocks. When an exception occurs on this kind of delay slot, DELAY_SLOT_CLEARME flag cause a status confusion in exception handling. DELAY_SLOT_CLEARME flag should be cleared on exceptions. And some items are added to CPU status dump. (Shin-ichiro KAWASAKI) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5066 c046a42c-6fe2-441c-8c8c-71466251a162
