|
version 0.?.?:
|
|
|
|
05.01.2022: Rhialto
|
|
version 0.7.2:
|
|
- Improved error messages for bad addressing modes
|
|
(due to gitlab issue #10)
|
|
- Undefined symbols are now listed in the symbol table.
|
|
- The weird way the unary "operator" % works in expressions is
|
|
now implemented.
|
|
The docs on page 3-8/9 aren't very precise but testing showed
|
|
that any expression with a register in it can be used as a
|
|
register, and (if used to define a symbol) is listed in the
|
|
symbol table as such. %3+1 is <%3>+1 is R4.
|
|
- Fixed registers being used in .word or immediate operands:
|
|
no longer generated as being relocatable expressions.
|
|
- 'make tests' works more portably.
|
|
|
|
16.05.2021: Rhialto
|
|
version 0.7.1:
|
|
- Fixed immediate source operand of LDEXP, LD[IL][FD]
|
|
which is an integer, unlike several other FPP instructions.
|
|
(gitlab issue #7)
|
|
- Start each pass with .DSABL LSB (gitlab issue #8)
|
|
|
|
19.03.2021: Rhialto
|
|
version 0.7:
|
|
- Fixed the end-of-line check for MARK, EMT, TRAP.
|
|
- Left/right shift operator _; disabled when the -yus option is used.
|
|
Contributed by Stephen Casner.
|
|
- Added some missing instructions: LDCFD, CSM, TSTSET, WRTLCK.
|
|
|
|
13.02.2021: Rhialto
|
|
version 0.6:
|
|
- Fixed rounding issues with floating point literals.
|
|
- Fixed FPP instructions which take fp immediate operands.
|
|
- Fixed bounds check on FPP AC0-3 operands.
|
|
- Fix listing to show a % before values that represent a register
|
|
number.
|
|
- Added checks for junk text following correct code. This revealed
|
|
some small other issues, now fixed.
|
|
- Added CIS instructions; as an extension, for the Inline variants
|
|
you can specify the descriptor addresses etc as arguments to
|
|
the instruction (much like an implied .word).
|
|
|
|
25.04.2020: Rhialto
|
|
version 0.5:
|
|
- Fixed bug with checking addressing mode for JSR and bugs
|
|
with .REPT 0, unneeded relocation on pc-relative mode.
|
|
- Very simple .LIST and .NLIST implementation.
|
|
- Add ^pl and ^ph expressions from 2.11BSD's m11.
|
|
- Object-ified macro libraries with an eye to support the .sml
|
|
files from 2.11BSD's m11. But since the given file does not
|
|
just contain .MACROs (it even contains conditionals) I'm not
|
|
sure how it is supposed to work.
|
|
- Added 2.11BSD/m11 as test files. To make this reasonable, a
|
|
few small features they use have been recognized and ignored.
|
|
- Add -rsx and -rt11 to switch object file format (from Kevin Handy)
|
|
- Add obj2bin from https://github.com/AK6DN/obj2bin.git
|
|
|
|
09.11.2015: Rhialto
|
|
version 0.4:
|
|
- Fixed various bugs. The most notable was extensive use-
|
|
after-free in the expression tree, which crashed on NetBSD but
|
|
apparently not on other systems.
|
|
- Lots of changes to make this MACRO11 more like the MACRO11 of
|
|
RSX-11M+ 4.6. I used Kermit-11 source files for comparison.
|
|
"The Manual" I'm refering to is
|
|
AA-KX10A-TC_PDP-11_MACRO-11_Reference_Manual_May88.pdf at
|
|
www.bitsavers.org/pdf/dec/pdp11/rsx11/RSX11Mplus_V4.x/4a/ and
|
|
I use an installed system to double-check.

19.4.2009: JH
|
|
version 0.3
|
|
- bugfix: Illegal labels and illegal opcodes are processed as
|
|
"implied .WORD" directives.
|
|
Expression errors in "do_word()" did not process any input character,
|
|
so parser did go into an endless loop.
|
|
- Switchable syntax extensions with -yxx options:
|
|
symbol len can be adjusted with "-ysl" command line option.
|
|
"-yus" option allows underscore "_" char in symbols.
|
|
This was needed to process code generated by my favorite disassembler.
|
|
- command line help added (-h option)
|
|
|
|
17.4.2009: JH
|
|
version 0.3
|
|
- ".INCLUDE" re-enabled
|
|
- refactoring: big 6000+ lines "macro11.c" split into 10 modules.
