Aurelien Jarno 1f486815ae target-sh4: MMU: fix mem_idx computation
The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0
corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user
mode (SR_MD = 0).

Blue Swirl 72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

aurel32 d8299bccf2 SH4: Implement FD bit
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.

aliguori a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
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.

Current QEMU code, in addition to the above, also clears the high

aurel32 0fd3ca30c4 sh4: CPU versioning.
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.
