Hello all,
I could use some pointers on romcc. About ten to twelve rom-images have emanated on my workstation and the target boots as it should, but a few times (not every) the output from the emulator has contained pointers on invalid code, such as:
0002:2c5f: 00 ILLEGAL EXTENDED X86 OPCODE!
or
0000:4002: 01 ILLEGAL EXTENDED X86 OPCODE!
This message is coming from the x86emu. Your VGA option rom seems to go off board. Please send the full log.
Now I took to the measure of testing romcc with the delivered test suite. Most unfortunately this fails as the trailing text demonstrates.
I'm not sure whether they're all supposed to pass at all. Eric?
My question is this: Is it me that cannot figure things out properly regarding the use of romcc? Is it gcc-3.3 that is falling short, or does Coreboot apply tailored options to romcc, options that I did not find so far.
The two problems you are seeing are completely unrelated. Though, updating your gcc to at least 4.2 might make sense.
