(or before) to 11.0-RELELASE at some point for arm elf-hosted buildworld activity will face the issue without having the opportunity to build a -mlong-calls enabled context with a smaller clang first: > > BEAGLEBONE > CUBOX-HUMMINGBOARD > GUMSTIX > RPI-B > PANDABOARD > WANDBOARD > > So does the "all but clang libraries" -mlong-calls use need to be MFC'd? Even this may require updating from older 10.x's to a 10.y that has those -mlong-calls in place before going to 11.0-RELEASE (or later). > > A similar point will be an issue for switching from such a 10.x (or before) to 11.0-CURRENT once clang 3.8.0 has been imported: it may require a middle stage of switching to a then-older 11.0-CURRENT first (such as -r294499). Personally, I think we should make the dependent on the compiler version when we bring them back / before we MFC things.
