Section: New in release 0.91
----------------------------------------------------------------------
Added anonymous labels (- + -- ++ --- +++ etc.). Every other assembler
seems to support them, so I added them to ACME as well... :)
New POs: "!warn MESSAGE", "!error MESSAGE", "!serious MESSAGE"
New CLI option: "--maxdepth NUMBER" sets maximum recursion depth for
macro calls and the "!source" pseudo opcode.
ACME now gives a warning when assembling JMP($xxff) on 6502/6510
because that instruction is broken on those CPUs.
After giving the error "Target out of range", the error "Number out of
range" is now suppressed.
Corrected code example in QuickRef.txt (why didn't anyone tell me? :))
Added additional example source code.
----------------------------------------------------------------------
Section: New in release 0.90
----------------------------------------------------------------------
Arithmetic shift right now has some watchdog code and should work
regardless of compiler.
Corrected some typos in error messages and docs.
New CLI option: "--cpu CPU_TYPE"
The output file format chosen with "--format FORMAT" is now used as
default when "!to" is used without format keyword.
Again: Tidier code.
----------------------------------------------------------------------
Section: New in release 0.89
----------------------------------------------------------------------
Support for more undocumented ("illegal") opcodes: anc, arr, asr, sbx,
dop, top, jam. See Illegals.txt for more info.
Change in shift operators: Logical shift right (">>" or "LSR") has on
most platforms actually been an arithmetic shift right all the
time! Therefore, ">>" now *officially* performs an arithmetic
shift right (can also be written as "ASR"), while ">>>" has been
added to perform a logical shift right (can also be written as
"LSR"). Note: This is about ACME's maths parser and has nothing to
do with the 6502 mnemonics "asl" and "lsr".
Finally added a "-o" command line option to set the output file! See
QuickRef.txt for info on the other new CLI options (--format,
--labeldump, --maxerrors, --setpc, --initmem, --version).
Fixed bug: "!align" could be used while program counter undefined.
Fixed bug: Numbers before mnemonics are no longer skipped (or rather,
implicit label definitions are no longer accepted if the label
name starts with a digit).
Change: Much better algorithm to compute to-the-power-of (read: it's
no longer braindead).
Some more internal tidying.
----------------------------------------------------------------------
Section: New in release 0.88
----------------------------------------------------------------------
Fixed architecture-dependent bug introduced in release 0.87.
Fixed bug: Unknown !cpu keywords could cause crashes.
Fixed bug in !ct "filename" nesting.
----------------------------------------------------------------------
Section: New in release 0.87
----------------------------------------------------------------------
Support for some undocumented ("illegal") opcodes: slo, rla, sre, rra,
sax, lax, dcp, isc. To use these, choose the 6510 cpu.
Two error messages gone: "Sorry, feature not yet implemented." and
"Chosen CPU does not support this command and/or addressing mode."
Explanation of new error message ("There's more than one character.")
added to docs.
----------------------------------------------------------------------
Section: New in release 0.86
----------------------------------------------------------------------
The "!convtab" pseudo opcode can now be given the file name of a
conversion table. The file must hold exactly 256 bytes.
Improved docs a bit (more and better examples, more info on verbosity
CLI switch).
If no "!to" pseudo opcode has been found, ACME will tell you so.
