arg
is any of:
ai | noai enables/disables procedure in-lining using
heuristics at optimization level 2.
ca | noca enables/disables code alignment; generate (do
not generate) alignment directives prior to labels
that are not entered from above.
cb | nocb enables/disables use of compare and branch
instructions.
lp | nolp enables/disable code generation of functions
using the
bal calling sequence at optimization
level 1 or 2.
nolp is the default at optimization
level 1, and
lp is the default at optimization
level 2.
pf | nopf This option is obsolete. It is recognized but has
no effect.
sa | nosa determines whether or not the compiler risks
generating memory references that are not
provably aligned. If
Fnosa is selected, the
compiler occasionally generates potentially
unaligned references when it seems
advantageous to do so. When
Fsa is enabled,
sequences of smaller memory references are
used instead of larger ones that might not be
correctly aligned.
