From 61c9b97d7b81cc2c013b423bf1763a92b14fcae3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [clangd][xpc][cmake] Respect explicit value of
CLANGD_BUILD_XPC
We shouldn't prevent user from disabling XPC framework build on Darwin.
However, by keeping it on by default our CI systems also test
it by default on macOS.
Based on user request:
http://lists.llvm.org/pipermail/cfe-dev/2019-March/061778.html
Differential Revision: https://reviews.llvm.org/D59808

commit cd5603a4767277a29d3e67a9c3f2a5d2129cd973
Author: Sterling Augustine <saugustine@google.com>
Date: Tue Mar 19 20:01:59 2019 +0000
Add --unwindlib=[libgcc|compiler-rt] to parallel --rtlib= [take 2]
"clang++ hello.cc --rtlib=compiler-rt"
now can works without specifying additional unwind or exception
handling libraries.
This reworked version of the feature no longer modifies today's default
unwind library for compiler-rt: which is nothing. Rather, a user
can specify -DCLANG_DEFAULT_UNWINDLIB=libunwind when configuring
the compiler.
This should address the issues from the previous version.
Update tests for new --unwindlib semantics.
