This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
(the old cc has been tagged with "gcc_2_6_3_final" so we have a reference
point in case of unforseen disasters...)
This has the objc backend active, and I think I've managed to get the
f77 f2c support through in one piece, but I don't know fortran to test it.
A 'make world' change and libobjc commit will follow.
If you normally do 'make -DNOCLEAN world', do not do so this time, I know
it can fail with groff.
This version of gcc makes a **LOT** more warnings on our kernel.
Notice that the libgcc DOESN'T change number, because there are no
changes.
Also now the gnu2bmake stuff is synchronized again.
I commit this so that others can test too.
You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.
Thanks to Bruce for rounding up our changes to gcc.
no longer link against the whole library, since they don't require much
from it, but just compile the few small modules they actually need static.
This should save a measurable amount of space; compare:
-r-xr-xr-x 1 bin bin 155648 Sep 18 18:00 cc1*
-r-xr-xr-x 1 root bin 1048576 Sep 18 17:33 cc1.noshae*
Of course, the library takes up a bit of space, but when you add in the
savings from the C++ compiler, you more than make up the difference:
-r--r--r-- 1 bin bin 1157344 Sep 18 18:27 /usr/lib/libcc_int.so.26.0
-r-xr-xr-x 1 bin bin 491520 Sep 18 18:27 /usr/libexec/cc1plus*
automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
