stephena 72185d0848 Cleaned up formatting in Thumb ARM emulation code.
Wrapped THUMB ARM emulation in a define, so that it can be excluded
from builds.  To enable it, the 'THUMB_SUPPORT' directive must be
included in the build process.  This has been added to the OSX
project files, but is still TODO for Linux and Windows.

Removed some obsolete include paths from the OSX project files,
dating back about 5 years or so.

stephena bcb8dfbc2b First pass at fixing formatting issues in the ARM emulation code.
Also fixed warnings when compiling on 64-bit compilers.

stephena ba1019a308 Updated documentation for missing commandline arguments.
Added infrastructure to System and Device classes to deal with CodeAccessBase
even when the bankswitching scheme bypasses the normal System::PageAccess
way of reading ROM space.  This allows bankswitching schemes 2E, AR, FE and
4A50 to support emulation core 'hints' for more accurate disassembly.  The
only scheme not supported now is MC, which isn't really working anyway (I've
never actually had a test ROM for this scheme).

It's getting close, folks ...

stephena c9ab109524 Converted several 'toString' methods to use stringstreams instead of
multiple concatentation of strings.  This should be faster, or at least
lead to less string constructor calls.

Output of 'ROW' directives in the disassembly now shows only 8 items per
line, instead of 16.  This allows to see all the bytes without having a
'...' in between.  A future release may customize this to the size of the
output area.

Fixed output from debugger 'disasm' command to properly align different
directive types and show GFX and PGFX output.

Bumped state file version to 3.3 final, since there are no further
changes to the code that will break the file format.

stephena 773092142e Added rule for recompiling the M6502.m4 script to the Makefile, because I'm
tired of doing it manually every time it changes.

Tweaked the handling of JSR, RTI and RTS commands, so they don't erroneously
mark associated addresses as CODE when in fact they're never actually
executed.

Several parts of the Distella code were marking areas as DATA, even though
it depending on knowing the values for the X and Y registers (which it
doesn't, as it's a static analysis).  As such, these areas are now marked
as ROW instead, since that's as precise as a static analysis can do.  The
processing blocks are left there, though, in case Distella is improved in
a future release.

All the above changes allow for better disassembly with less
'false positives' (ie, areas marked as CODE or DATA when they really aren't).

stephena b756f8c14a Fixed several errors/crashes when attempting to open a window larger than

manager normally takes care of it.  In the case of fullscreen mode, however,
it is never allowed, and an error message is shown.

to use curly braces {} instead of apostrophes.  This matches the
functionality from older releases.

Fixed debugger prompt messages to show correct info when opening
various files (config files, autoexec, etc).

The debugger 'type' command now accepts a range of values.

Reverted handling of ROMs that aren't in the internal database;
they're inserted with their extension again, just as in older
releases.

stephena 3011aa7d12 Addresses directly after a relative branch should not be marked as DATA
in the emulation core, since at that point it's unknown what they are.
I suspect there are other places in the core where this is being done,
so I need to go over the entire M6502.m4 file again.

In Distella, when tentatively marking an address range as CODE, stop
when encountering the first address marked as DATA/GFX/PGFX by the
emulation core.  This is required since Distella will happily disassemble
CODE as far as possible, but addresses specifically marked as
DATA/GFX/PGFX obviously indicate the CODE range is finished.  This is
also why it's so important to correctly mark areas as DATA; the
Distella algorithm depends on accurate information to know when to stop.

2010-10-24 14:55:42 +00:00
stephena bea8ac0ffd Properly implemented an hierarchy wrt marking an address in the disassembly
in a consistent way.  Directives set manually have top priority, then the
results from a dynamic analysis (aka, from actually running the code), and
finally from a static analysis (aka, Distella itself).

Sometimes Distella will mark a section as CODE even if it hasn't been
marked as such dynamically.  This occurs after a relative branch, which
Distella has no idea how to evaluate.  It's possible that the code will
be executed eventually, but also that it will never be executed.  As such,
these lines are marked with a '*', indicating that disassembly results
are tentative.  If you get weird looking disassembly for these addresses,
it's probably a hint that it isn't really code at all.

PC addresses in the disassembly labels are now aligned with labels, and
shown in a lighter color.  These can still be toggled on and off.

stephena 0af08634a8 Addresses marked with certain directives within Distella should not propagate
to the emulation core.  That is, if something is determined to be CODE in
Distella and *not* in the emulation core, then it shouldn't be marked as such.
Note that the disassembly will still show it as CODE; it's just that the core
will not.  This fixes issues with manually specifying directives from the
debugger prompt, whereby setting a directive and later turning it off never
actually turns it off (as it was being permanently set).
