|
|
|
| 117 |
|
|
v0.1.X 99/12/20 added Intel hex option (SLB)

|
| 119 |
|

|
| 124 |
|
|
(hey, this isn't CP/M anymore :-)
|
| 125 |
|
|
added a bit of intelligence to command line processing
|
| 126 |
|
|
loads file(s) into internal storage prior to processing
|
| 127 |
|
|
(this aids a lot in preventing recursive invocations)
|
| 128 |
|
|
added LIB,LIBRARY pseudoop (same as INCLUDE)
|
| 129 |
|
|
added OPT,OPTION pseudoop
|
| 130 |
|
|
v0.4 01/10/22 added -t switch to increase compatibility with the
|
| 131 |
|
|
TSC FLEX Assembler line, which uses a slightly more
|
| 132 |
|
|
rigid source file format
|
| 133 |
|
|
v0.5 01/10/23 added SETPG, SETLI, PAG, SPC, NAM(TTL,TITLE), STTL, REP(RPT,REPEAT)

|
| 139 |
|
|

|
| 140 |
|
|
v0.10 01/11/15 ASM and VERSION texts predefined
|
| 141 |
|
|
v0.11 01/11/27 increased TSC FLEX Assembler compatibility (labels made case sensitive)
|
| 142 |
|
|
v0.12 01/11/28 added some convenience mnemonics and simulated 6800 instructions to
|
| 143 |
|
|
increase TSC FLEX Assembler compatibility
|
| 144 |
|
|
v1.02 01/04/11 check for address range overlaps implemented
|
| 145 |
|
|
v1.03 02/09/24 macro parser had an error; corrected
|
| 146 |
|
|
v1.04 02/12/10 error message output adjusted for Visual C++ 6.0 IDE compatibility
|
| 147 |
|
|
added OPT LFN/NLF for that purpose
|
| 148 |
|
|
v1.05 02/12/23 crude form of backwards ORG added to binary output
|
| 149 |
|
|
v1.06 03/06/10 added OPT LLL/NLL to include/suppress listing of LIB lines
|
| 150 |
|
|
v1.07 03/06/23 outsymtable() only starts with a page feed if current line
|
| 151 |
|
|
is is NOT the first line on a page
|
| 152 |
|
|
v1.08 03/07/01 SKIP count for the IF(N) and IF(N)C statements added to
|
| 153 |
|
|
normal statements (i.e., outside macro definitions)
|
| 154 |
|
|
v1.09 05/06/02 some cleanups
|
| 155 |
|
|
added -r format for FLEX9 RELASMB compatible output
|
| 156 |
|
|

|
| 157 |
|
|
REL|NOR option added
|
| 158 |
|

|
| 159 |
|
|
M68|H63 option added
|
| 160 |
|
|
v1.10 05/06/03 made options available as numeric strings
|
| 161 |
|
|
added local label support
|
| 162 |
|
|
added SYMLEN
|
| 163 |
|
|
TXT|NTX option added
|
| 164 |
|
|
v1.11 05/06/06 IFD/IFND directives added
|
| 165 |
|
|
added special checks for "0,-[-]indexreg" and "0,indexreg+[+]"
|
| 166 |
|
|
when determining the postbyte for indexed addressing modes
|
| 167 |
|
|
v1.12 05/06/20 OPT CON|NOC correctly implemented
|
| 168 |
|
|
v1.13 skipped for users that might have an uneasy feeling about
|
| 169 |
|
|
the number "13" >:-)
|
| 170 |
|
|
v1.14 05/08/01 text symbol replacement enhanced; it was a bit TOO general.
|
| 171 |
|
|
Now, &xxx is only treated as a text variable when xxx REALLY
|
| 172 |
|
|
is a text symbol; in all other cases, it's not preprocessed.
|
| 173 |
|
|
Let the assembler engine handle eventual errors.
|
| 174 |
|
|
Thanks to Peter from Australia for pointing this out!
|
| 175 |
|
|
v1.15 05/08/02 only 1 local label was allowed per address; now, as many as
|
| 176 |
|
|
possible can be at the same location.
|
| 177 |
|
|
Thanks to Peter from Australia for pointing this out!
|
| 178 |
|
|
v1.16 05/08/05 SETDP is illegal in relocating mode!
|
| 179 |
|
|
SETDP without any parameter DISABLES Direct mode entirely.
|
| 180 |
|
|
Cured an interesting bug... the following sequence:
|
| 181 |
|
|
ORG 1
|
| 182 |
|
|
LDA TEST
|
| 183 |
|
|
SHIT NOP
|
| 184 |
|
|
ORG 1
|
| 185 |
|
|
TEST RMB 1
|
| 186 |
|
|
caused a phase error; this was caused by the invalid
|
| 187 |
|
|
assumption in scanlabel() that forward references have
|
| 188 |
|
|
a higher memory location than the current address.
|
| 189 |
|
|
Thanks to Peter from Australia for pointing this out!
|
| 190 |
|
|
v1.17 08/08/05 made tests for above problem more rigorous; now ANY forward
|
| 191 |
|
|
reference to a label that's not yet defined is treated as
|
| 192 |
|
|
uncertain.
|
| 193 |
|
|
Removed a nasty bug that caused the following code to produce
|
| 194 |
|
|
incorrect values:
|
| 195 |
|
|
org $8000 (anything >= $8000 will do)
|
| 196 |
|
|
lbl rmb 8
|
| 197 |
|
|
SizeBad equ (*-lbl)/2
|
| 198 |
|
|
OPT NOL changed to OPT NO1 to allow implementing OPT LIS|NOL.
|
| 199 |
|
|
OPT LIS*|NOL added
|
| 200 |
|
|
Thanks to Peter from Australia for pointing these out!
|
| 201 |
|
|
v1.18 09/08/05 backward search for local labels now searches for "<= local
|
| 202 |
|
|
address" instead of "< local address"
|
| 203 |
|
|
Thanks to Peter from Australia for pointing this out!
|
| 204 |
|
|
Added INCD / DECD convenience mnemonics
|
| 205 |
|
|
(realized as ADDD/SUBD 1)
|
| 206 |
|
|
v1.19 10/08/05 Added a bunch of 6800-style mnemonics; if they conflict
|
| 207 |
|
|
with 6809 mnemonics ("INC A" for example), they are only
|
| 208 |
|
|
active in TSC mode
|
| 209 |
|
|
v1.20 16/08/05 changed special checks for
|
| 210 |
|
|
"0,-[-]indexreg" and "0,indexreg+[+]"
|
| 211 |
|
|
to include all known labels and changed the scope to
|
| 212 |
|
|
",[-[-]]indexreg[+[+]]"
|
| 213 |
|
|
v1.21 21/02/06 Bug in "xxx >0,reg" found by Margus Kliimask
|
| 214 |
|
|
v1.22 03/09/08 Addded BIN(ARY) pseudo-op to include binary files
|
| 215 |
|
|
v1.23 13/02/09 6800 code generation added
|
| 216 |
|
|
accept multiple input files (first one defines default
|
| 217 |
|
|
output and listing file names)
|
| 218 |
|
|
v1.24 13/02/09 made compilable with gcc
|
| 219 |
|
|
v1.25 05/03/09 6800 alternate mnemonics work better now
|
| 220 |
|
|
v1.26 14/03/09 assembling DOS format files in Loonix works better now
|
| 221 |
|
|
v1.27 20/01/10 LPA/NLP options added
|
| 222 |
|
|
v1.28 21/04/10 INCD/DECD produced invalid code
|
| 223 |
