When gas encounters the statement:
fldws -4(%r22),%farg0
it issues the error:
Error: Field out of range [0..31] (-59).
Error: Invalid operands
similarly for %farg1, %farg2, and %farg3, it issues similar warnings with -58,
-57, and -56 as the constant.
HP's native assembler accepts the statement. When I disassemble the output of
the native assembler, it converted that statement to:
fldw -4(,r22),fr4
So it appears %farg0 should be a synonym for %fr4. As a workaround, I've
modified my code to use %fr[4-7] instead of %farg[0-3] and gas is happy with
this.
This bug is present in binutils-2.15 and in the binutils-050404 snapshot I just
tested.
