[PATCH] D105765: Prepare Compiler-RT for GnuInstallDirs, matching libcxx, document all

[John Ericson via Phabricator via cfe-commits]

Ericson2314 added inline comments.

Comment at: compiler-rt/docs/BuildingCompilerRT.rst:12-22
+The instructions on this page are aimed at vendors who ship Compiler-RT as part of an
+operating system distribution, a toolchain or similar shipping vehicules. If you
+are a user merely trying to use Compiler-RT in your program, you most likely want to
+refer to your vendor's documentation, or to the general documentation for using
+Compiler-RT :ref:`here <using-libcxx>`.

Fair enough. Removed.

Ah there is no such section for `compiler-rt/docs`. I deleted and reworded.


================
Comment at: compiler-rt/docs/BuildingCompilerRT.rst:59
+  ``-DCOMPILER_RT_INSTALL_PATH:PATH=...`` not
+  ``-DCOMPILER_RT_INSTALL_PATH:PATH=...``, otherwise CMake will convert the
+  path to an absolute path.

Oops. Yes.


================
Comment at: compiler-rt/docs/BuildingCompilerRT.rst:87
+
+  Path where Compiler-RT headers should be installed. If a relative
+  path, relative to ``COMPILER_RT_INSTALL_PATH``.

Says "data" like the CMake variale description does now too.
