------- Additional Comments From pinskia at physics dot uc dot edu 2003-06-29 12:41 -------
To not align loops with -falign-* use 1 as the alignment (like the documentation says to
do at least for align-functions but it applies for all of them), since it use n not 2^n, unlike -
malign-*. See the documentation, there is one thing the documenation should say but
does not:
If n is not specified (or is zero), use a machine-dependent default.
The or is zero part is not there I will sumbit a patch for and resync all the -falign-* options
sos they look the same.
This is case where the documentation is not clear but I will change that.
