2008-12-10target-sh4: Add SH bit handling to TLBaurel32
This patch adds SH bit handling to sh4's TLB, which is a part of MMU functionality that had not been implemented in qemu. Additionally, increment_urc() call in cpu_load_tlb() is deleted, because the specification explicitly says that URC is not incremented by an LDTLB instruction (at Section 3 of SH7751 Hardware manual(REJ09B0370-0400)). Even though URC is not needed to be strictly same as HW because it is a random number, this condition is not negligible.

2008-12-07SH4: Implement FD bitaurel32
SH4 manual say that if a floating point instruction is executed while FD bit in the status register is 1, an exception should be raised. QEMU presently does not do that, so the kernel does not initialize FP state for any thread, nor does it save/restore FP state. The most apparent consequence is that while recent gcc/libc expect double-precision mode to be set by kernel, they run in single-precision mode, and all FP code produces wrong values. This patch fixes this. It also fixes a couple of places where PC was not updated before handling an exception, although both those places deal with invalid instruction and don't lead to any user-visible bugs.

2008-12-07SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).balrog
Main purpose of this is to delete *physical = address & 0x1fffffff; at target-sh4/helper.c:449, using new mmio rule introduced by #5849 This masking is a nice trick to realize P4/A7 duality of SH registers. But, IMHO, it is logically wrong. Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have one more address called A7 which is usually P4 address with upper 3bits masked. This is an address only appears in TLB's physical address part. Current code use trick writing drivers as if they are really in A7 (that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

2008-11-18Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the succeeding enhancements this series comes with. First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching to dynamically allocated data structures that are kept in linked lists. This also allows to return a stable reference to the related objects, required for later introduced x86 debug register support. Breakpoints and watchpoints are stored with their full information set and an additional flag field that makes them easily extensible for use beyond pure guest debugging.
