Re: Add Android related compilation options and multilib options
I firstly have tried to mimic the new scheme on SH. But later I found
that on SH, the orginal t-mlib-* files are very simple. Each file just
gives an MULTILIB_OPTIONS value. So it is very easy to unify these
t-mlib-* files.
For arm target, the t-mlib-* files contain not only MULTILIB_OPTIONS
values, but also MULTILIB_DIRNAMES, MULTILIB_EXCEPTIONS, and
MULTILIB_MATCHES.
I haven't found an easy way to unify these t-mlib-* files into config.gcc.
I can use CASE statement to group these specifications together. But I
am not sure if this approach is better than individual t-mlib-* files.
SH previously had 24 t-mlib-* files. We only have 3 t-mlib-* files for
arm. So I guess maybe it is ok to leave them this way? If there are
more t-mlib-* needed in the future, we can change the scheme.
If anyone has better idea, I am very happy to take it.
Thanks very much!
