I've just got an "internal compiler error" message while trying to compile some code. I had a function that takes 5 byte-sized parameters - whenever I try to call the function, I get an internal error. It does not matter if the function is defined in the module, or declared extern. I compiled with just "msp430-gcc -c t.c", but the options don't matter. The workaround was pretty simple - declare the arguements as 16-bit wide, so I am not in a hurry for a fix, but I imagine you would like to fix it anyway.
The gcc version I am using is just before the bitfield definitions of the
ports, compiled from cvs on 5th December on Cygwin. I note that the file
"recog.c" that is mentioned in the error message is not part of the msp430
patches - could this be a general gcc bug? I tried compiling using cygwin
gcc (2.95.3-5), and it did not give any error.
mvh.
