Disassemblers are now independant classes. Not only the code is
cleaner, but unidasm has access to all the cpu cores again. The
interface to the disassembly method has changed from byte buffers to
objects that give a result to read methods. This also adds support
for lfsr and/or paged PCs.
* Created a more flexible imgtool::datetime structure for use within Imgtool
This is intended to replace most usage of time_t
* Changing the granularity of imgtool_clock from 1ms to 100ns, as per Vas' suggestion
* Created arbitrary_datetime in timeconv.h to facilitate interpretation of datetime info
I concluded that invoking std::mktime on manually assembled std::tm is bad, because it is indeterminate how the std::tm members may be "dominant". This required that I go further in imgtool, and update a number of drivers and eliminate the parameter of imgtool::datetime that takes std::tm.
- Removed ACORN_CPM_FORMAT, same geometry as ACORN_SSD_FORMAT/ACORN_DSD_FORMAT
- Improved find_size/identify for SSD/DSD formats
- ACORN_DOS_FORMAT 640K now handled as ACORN_ADFS_OLD_FORMAT
- Fixed geometry for ACORN_DOS_FORMAT 800K
bbc_acorn8271: Added Amcom DFS A7874
bbc_opus8272: New Opus 8272 FDC device with DDOS 3.00, not yet working.
wd177x_dsk: Apply sector_count and gaps to track description.
* Unify code for copying PNG data into bitmap for MAME and pngcmp
* Fix upsampling of monochrome PNGs (need to splat across byte)
* Add support for greyscale+alpha
* Detect more unsupported conditions rather than just behaving badly
(nw) This is the path of least resistance, and I plan to fix it up
later, I just wanted to get it to actually work first. Decompression
and unfiltering is fully supported, at least for all the pixel formats
that previously worked. Expanding 1/2/4bpp to 8bpp should work
properly, too. Bitmap mapping for Adam7 is only implemented in
rendutil.cpp which is whate everything in MAME uses. The function in
png.cpp (used by pngcmp) has not been updated. At some point I'll unify
at least one of the functions in rendutil.cpp with the one in png.cpp
and we can go from three functions that need to do the mapping down to
two at the most.
Refactor server_{ws,http}.hpp into separate interface and implementation headers.
When shutting down the HTTP server, also explicitly stop the asio::io_context.
