rS360667: MFC r330366 (by emaste):
rS335447: Rework how the ld link is handled in WORLDTMP from r322811.
Summary

LLD_BOOTSTRAP (build) is independent of LLD_IS_LD (installed) so they
should not be based on each other.

This is related to upcoming WITH_SYSTEM_LINKER work.

Sponsored by: Dell EMC

Test Plan

Did various WITHOUT_LLD and WITHOUT_LLD_IS_LD tests (with WITH_LLD_BOOTSTRAP set)

This is not strictly needed for make buildworld but DIRDEPS_BUILD actually will complain if 2 ld.1 files get installed.

We really need some documentation for the magic TOOLS_PREFIX tests

All it really means is that it is in the 'cross-tools' phase of buildworld and is building a cross-toolchain for the build only.

Doesn't this one need (!defined(TOOLS_PREFIX && ...) || (defined(TOOLS_PREFIX) && ...) like the other case?

bdrewery updated this revision to Diff 44053.Jun 19 2018, 1:53 AM

Reduce duplicated logic and add missing check on TOOLS_PREFIX.
