GXemul Code2

Release 0.4.6.5.

20080611 Correcting the ARM pc-relative load fix; the wrong address
variable was used. Also, the pc-relative _load_ code was
used for stores as well, which was completely incorrect.
On ARM, since pc-relative loads are converted into immediate
movs, on writes to pages that contain such translations, the
ENTIRE page must be invalidated, not just the 1/32th that
was code. This has now been implemented.

Adding a dummy Jornada 728 mode; same as 720 but with 64 MB ram.

Release 0.4.6.4.

20080605 Fixing a corner case in ARM pc-relative loads, which was
unimplemented before. (Triggered by doing builds of pkgsrc
stuff inside emulated NetBSD/cats.)
20080610 Applying a patch from Jiri Svoboda, which implements the
ARM "bkpt" instruction.

Better error message when failing to open a disk image.

Specific version numbers of FreeBSD.

Updating from January 2008 to June 2008.

Working on the main loop, GXemul::ExecuteCycles(), which should call each component s Run function in suitable proportions. Adding a CPUComponent base class, from which MIPS_CPUComponent inherits.
