@item -mold-align
Enable structure-alignment compatibility with Intel's gcc release version
1.3 (based on gcc 1.37). This option implies @samp{-mstrict-align}.
@item -mlong-double-64
Implement type @samp{long double} as 64-bit floating point numbers.
Without the option @samp{long double} is implemented by 80-bit
floating point numbers. The only reason we have it because there is
no 128-bit @samp{long double} support in @samp{fp-bit.c} yet. So it
is only useful for people using soft-float targets. Otherwise, we
should recommend against use of it.
