GCC Configure Options Need Checked

[William Harrington]

Greetings.

We need to check through the GCC configure options. Some have been around forever, and some added because of 4.6 or 4.7 or 4.8. Some are now auto enabled by default and some may not be required anymore or maybe some have been added.

commit 5e6856493bd0c291867288b7b07af45d8f625dec is from Chris and he has removed: --enable-shared --enable-c99 --enable-long-long as they are enabled by default.

It is critical we don't mess with the cross tools compiler options as much as possible as the host may not be a GNU/Linux host and some options may react different.

Working my way through with gcc-4.9.1, can't really see anything else at the moment, need to remove --disable-mudflap as it's been depreciated and add --disable-libvtv --disable-libcilkrts --disable-target-libiberty to chap 5.13, and possibly --disable-isl-version-check if we move to isl-0.13

Also need to add --enable-install-libiberty to chap 5.15 and 10.19 ?

Needless to say the specs patch needs redoing, will post that to the list later

We need to create separate tickets for changes required for ISL 0.13 upgrade and GCC 4.9 upgrades. This ticket is just for cleaning up our current book's configure options for GCC.

blackadder mentioned "need to remove --disable-mudflap as it's been depreciated and add --disable-libvtv --disable-libcilkrts --disable-target-libiberty to chap 5.13"

Have a build going right now as I need to test some other things Chris and I have discussed at the IRC channel.

ok will do, looked generic to me

We'll keep the gcc configuration option checks in the gcc 5.2 ticket. Makes more sense to be there than have a separate ticket.
