<div>
<pre>If you use `-mno-outline` along `-flto` with clang, the linker (which does the
actual compiling) is not instructed that it should disable the outliner.
Same if you use `-mllvm -enable-machine-outliner=never`.
Other flags, like -march=something are translated to linker plugin options when
used at link time. Some flags, when used at compile time, end up in the object
files and are used automatically at link time with LTO (-march does that too,
in fact).</pre>
