Hello. I just recently upgraded to:
SDCC :
cs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.7.0 #4818 (Aug 18 2007) (UNIX)
I have the following ASM code (which used to assemble,
compile, and link fine):
.module serialA
.globl _main
.area DSEG (DATA)
.area OSEG (OVR,DATA)
.area SSEG (DATA)
.area ISEG (DATA)
.area BSEG (BIT)
.area XSEG (XDATA)
.area CSEG (CODE)
.area GSINIT (CODE)
.area GSFINAL (CODE)
.area GSINIT (CODE)
_main:
mov scon,#0x52
setb tr1
mov tmod,#0x21
mov th1,#0xFA
mov r0,#0x07
mov r1,#0x0c
mov r2,#0x04
mov r3,#0x08
lcall and16
mov a,r0
lcall print_2dig_hex
mov a,r1
lcall print_2dig_hex
jnb ti,.
ljmp $0
and16: ; 16bit AND takes 6
cycles
xch a,r0
anl a,r2
xch a,r0
xch a,r1
anl a,r3
xch a,r1
ret
print_2dig_hex:
mov b,a
anl a,#0xf0
swap a
lcall write_ascii
mov a,b
anl a,#0x0f
lcall write_ascii
lcall print_space
ret
write_ascii:
mov dptr,#hexadecimal
movc a,@a+dptr
jnb ti,.
clr ti
mov sbuf,a
ret
carriage_return:
jnb ti,.
clr ti
mov sbuf,#0x0a
ret
print_space:
jnb ti,.
clr ti
mov sbuf,#0x20
ret
hexadecimal:
.db 48,49,50,51,52,53,54,55,56,57,65,66,67,68,69,70
I assemble the above ASM with:
/usr/local/src/sdcc/bin/asx8051 -o -l and16.asm
All appears to be OK at this point. It generates two
files:
and16.rel
and16.lst
I then compile with:
/usr/local/src/sdcc/bin/sdcc
-I/usr/local/src/sdcc/device/include
-L/usr/local/src/sdcc/device/lib
-L/usr/local/src/sdcc/device/lib/mcs51 --code-loc
0x8000 and16.rel
and get the following output:
ASlink-Warning-No definition of area HOME
This is wrong. Here is the output of and16.lnk:
-myuxi
-Y
-b HOME = 0x8000
-b ISEG = 0x0000
-b BSEG = 0x0000
-k /usr/local/src/sdcc/device/lib
-k /usr/local/src/sdcc/device/lib/mcs51
-k /usr/local/src/sdcc/bin/../share/sdcc/lib/small
-k /usr/local/share/sdcc/lib/small
-l mcs51
-l libsdcc
-l libint
-l liblong
-l libfloat
and16.rel
-e
Here is the output of and16.map:

It very clearly knows that HOME is 0x8000. Why does it
pretend to not know this? Any help is appreciated. 2.7
is turning out to be a big disappointment.
