2008-08-22[sh4] delay slot bug fixaurel32
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

2007-10-14Replace is_user variable with mmu_idx in softmmu core,j_mayer
allowing support of more than 2 mmu access modes. Add backward compatibility is_user variable in targets code when needed. Implement per target cpu_mmu_index function, avoiding duplicated code and #ifdef TARGET_xxx in softmmu core functions. Implement per target mmu modes definitions. As an example, add PowerPC hypervisor mode definition and Alpha executive and kernel modes definitions. Optimize PowerPC case, precomputing mmu_idx when MSR register changes and using the same definition in code translation code. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3384 c046a42c-6fe2-441c-8c8c-71466251a162
