CHANGELOG:
v9.9 (15-Aug-2019) [ALL] Added unions: .UNION (and .NEXTU and .ENDU).
[ALL] Added a new syntax to .DSTRUCT (old works, too).

[ALL] .ROW and .DATA should now work better with 16-bit
and 24-bit values.
[ALL] Defines with negative values are now parsed better.
[ALL] .BLOCK (and .ENDB) prints the block size once again.

object files.

define from inside a pending computation should work now.

command line.

now when using .LOROM / .HIROM. / .EXHIROM.

for 64Mbit ROM and 512kbit RAM types.
v9.8 (21-Jun-2019) [ALL] Deprecated and removed section's size giving inside
section's name string.

mess up listfiles any more.

placing them to the output ROM/PRG.
[ALL] The _sizeof_[label]s for labels that are followed by
a dotted .DSB etc. are now calculated correctly.

are 256 RAM banks for each SLOT. The number of ROM
banks doesn't affect the number of RAM banks any more.

[SPC] Fixed many 8-bit PC relative label references to be
direct references.
[Z80] Added shadow register aliases of opcodes that use
registers A, F, BC, DE and HL. For example, "AND A'"
assembles to the same (0xA7) as "AND A". The aliases
are meant for programmers who want to explicitly show
when they are using the shadow registers.
v9.7 (17-Apr-2018) [ALL] We now use CMake instead of plain Makefiles.
[ALL] Added INSTANCEOF support to .STRUCT.

RAM sections.
[ALL] It's possible to append to a section using APPENDTO.
[ALL] .IFDEFs can be used in .ENUMs and .RAMSECTIONs.
