Hi All.
I have the following problem with some autogenerated code (from nesC in
my TinyOS port to 8051*). It seems that a fairly obscure "= ? :" causes
problems with sdcc. The statement returns a bunch of warnings and fails
in the assembler with the following error:
sdcc -mmcs51 test_condit.c
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
test_condit.c:15: warning 94: comparison is always false due to limited
range of data type
?ASxxxx-Error-<o> in line 136 of test_condit.asm
<o> .org in REL area or directive / mnemonic error
...
Is the statement a valid C statement?
