+[hurd] Make getMainExecutable get the real binary path
+
+On GNU/Hurd, llvm-config is returning bogus value, such as:
+
+$ llvm-config-6.0 --includedir
+/usr/include
+
+while it should be:
+$ llvm-config-6.0 --includedir
+/usr/lib/llvm-6.0/include
+
+This is because getMainExecutable does not get the actual installation
+path. On GNU/Hurd, /proc/self/exe is indeed a symlink to the path that
+was used to start the program, and not the eventual binary file. Llvm's
+getMainExecutable thus needs to run realpath over it to get the actual
+place where llvm was installed (/usr/lib/llvm-6.0/bin/llvm-config), and
+not /usr/bin/llvm-config-6.0. This will not change the result on Linux,
+where /proc/self/exe already points to the eventual file.
+
+Patch by Samuel Thibault!
+
+While making changes here, I reformatted this block a bit to reduce
+indentation and match 2 space indent style.

From 198dceaf97e7bfbf0bade4d959ddef57ed4c3863 Mon Sep 17 00:00:00 2001
From: Sylvestre Ledru <sylvestre@debian.org>
Date: Thu, 29 Nov 2018 09:53:19 +0100
Subject: [PATCH 16/29] Change the i386 base line to avoid using sse2 extension
 This is more important now that llvm is built with clang instead of gcc.
 Thanks to Fanael Linithien for the patch (Closes: #914770, #894840)

-Subject: [PATCH] [analyzer] scan-build: if --status-bugs is passed, don't
- forget about the exit status of the actual build
-
-Summary:
-This has been bothering me for a while, but only now i have actually looked into this.
-I'm using one CI job for static analysis - clang static analyzers as compilers + clang-tidy via cmake.
-And i'd like for the build to fail if at least one of those finds issues.
-If clang-tidy finds issues, it will fail the build since the warnings-as-errors is set.
-If static analyzer finds anything, since --status-bugs is set, it will fail the build.
-But if clang-tidy find anything, but static analyzer does not, the build succeeds :/
