Local symbols are defined and used within the assembler, but they are
normally not saved in object files. Thus, they are not visible when debugging.
You may use the @samp{-L} option (@pxref{L, ,Include Local Symbols:
@option{-L}}) to retain the local symbols in the object files.

@section AT&T Syntax bugs
The UnixWare assembler, and probably other AT&T derived ix86 Unix
assemblers, generate floating point instructions with reversed source
and destination registers in certain cases. Unfortunately, gcc and
possibly many other programs use this reversed syntax, so we're stuck
with it.
For example
@smallexample
fsub %st,%st(3)
@end smallexample
@noindent
results in @samp{%st(3)} being updated to @samp{%st - %st(3)} rather
than the expected @samp{%st(3) - %st}. This happens with all the
non-commutative arithmetic floating point operations with two register
operands where the source register is @samp{%st} and the destination
register is @samp{%st(i)}.
