Bug 1748372 - Apply lld trunk fix for weak symbols with LTO on mac.
48 bytes, text/x-phabricator-request
Details | Review

LTO builds fail to run Firefox when linking with lld with:

[task 2021-12-31T11:06:29.330Z] 11:06:29     INFO - PID 2793 | dyld: Symbol not found: _replace_init
[task 2021-12-31T11:06:29.331Z] 11:06:29     INFO - PID 2793 |   Referenced from: /opt/worker/tasks/task_1640946733/build/application/Firefox Nightly.app/Contents/MacOS/libmozglue.dylib
[task 2021-12-31T11:06:29.332Z] 11:06:29     INFO - PID 2793 |   Expected in: flat namespace
[task 2021-12-31T11:06:29.332Z] 11:06:29     INFO - PID 2793 |  in /opt/worker/tasks/task_1640946733/build/application/Firefox Nightly.app/Contents/MacOS/libmozglue.dylib

lld doesn't respect the -Wl,-U,_replace_init flag (but only when LTO is on).
