Hello Kudu Jenkins, Adar Dembo,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/15058
to look at the new patch set (#4).
Change subject: build: restrict clang version, prefer lld, enable thinlto
......................................................................
build: restrict clang version, prefer lld, enable thinlto
* Restricts clang to at least version 6.0, which gets rid of a couple
older special cases.
* We now loop through linkers trying to prefer lld where available,
either using the version provided by the compiler with -fuse-lld or
explicitly passing the path to the toolchain lld. lld should be faster
than gold and GNU ld, and also has the advantage of being a known
quantity within our toolchain.
This fixes ASAN builds on my Ubuntu 18 machine, where the version of
gold that ships with the system can't seem to link ASAN executables.
* Switches the LTO build to use ThinLTO, which provides most of the
performance benefits but at much lower cost.
