Many thanks to those of you that sent a compiled copy of kmain, I was
able to determine where the error was. If you are trying to run binutils
on a machine that has char as an unsigned type, you will have the same
problem. I remember at least one person on this list saying they had
problems with binutils on SGI, and I am sure it is the same problem. The
fix is simple (relative to binutils-2.9.1):
gas/config/tc-h8300.c lines 924 and 1110
change (char) to (signed char)
If your C compiler doesn't support the signed keyword, either get an ANSI
compiler or you should be able to replace it with a macro like this:
#define signed_char_extend(x) ((x) & 0x80?(-1 & ~255) | (x):(x) & 255)
and then replace (char)... with signed_char_extend(...).
I will be sending the fix into the binutils maintainers, but until it is
incorporated you can make this simple change and rebuild gas.

| (...) I am the one (or one of them anyways) who had problems on SGI machines. Your fix improved things but did not fix them completely. The disassembler was also broken, and was still broken after making your change. You did inspire me, however. (...) (25 years ago, 3-Jan-99, to lugnet.robotics)
