s.d $f0,One
which when assembled as follows:
mips64orion-rtems-as -mcpu=4650 -v p1.s
generates this error message:
p1.s: Assembler messages:
p1.s:23: Internal error!
Assertion failure in macro_build at ../../src/gas/config/tc-mips.c line
2365.
Please report this bug.
Interesting. Reporting the error in this manner is clearly a bug in
gas.
However, as far as I can tell, the input is not valid for the 4650.
The 4650 has only single precision floating point, which means that it
can not support the s.d instruction for a floating point register. It
doesn't make any sense.
So I think there must be a compiler bug here as well.
I'll fix the bug in the assembler to report the error in a more
coherent fashion.
Ian
