Subject: Re: RFC: New approach to --with-cpu
Date: Tue, 30 Jul 2002 18:54:00 -0000 [thread overview]
Message-ID: <200207310131.g6V1VfNE021308@hiauly1.hia.nrc.ca> (raw)
From a PA standpoint, the main objection that I have to this approach
is that there seems to be a slight loss of flexibility. You use "with_cpu"
to set the default scheduling model. However, I was also planning to set
the default arch based on the target machine when a linker bug in handling
PA2.0 code is fixed. I view these options as independent although the
configure defaults would both be based on the target triplet. Thus,
it would be necessary to introduce a new configure option to handle
the arch default. In the future, I can see other default code generation
options being set-table.
I must admit that I don't really like the multilib concept and find
it a rather idea to build libraries for all scheduling models,
archs, etc. Thus, I don't find this justification attractive.
Dave
