Hi folks,
I’ve run into what I think might be a bug in sdas8051 as distributed with cdcc
4.3.0. The following test code:
.AREA CODE1 (ABS)
.ORG 0x0000
JZ 0x0000
JB 0x00,0x0000
ACALL 0x0000
.ORG 0x8000
L1:
LJMP L1
...produces:
$ sdas8051 -l -o test.s
test.s:7: Error: <p> phase error: label location changing between passes 2
and 3
?ASxxxx-Warning in line 8 of test.s
large constant 0xff808000 truncated to 16 bits
removing test.rel
...and the issue can also be seen in the .lst:
1 .AREA CODE1 (ABS)
000000 2 .ORG 0x0000
000000 60 00 [24] 3 JZ 0x0000
000002 20 00 00 [24] 4 JB 0x00,0x0000
000005 00 00 [12] 5 ACALL 0x0000
FF808000 6 .ORG 0x8000
p FF808000 7 L1:
FF808000 02 80 00 [24] 8 LJMP L1
Advice or workarounds appreciated? I ran into this when trying to re-assemble
some dumped ROMS from a DEC vt220; this is the simplest source sequence to
which I seem able to reduce the issue.
