$ toolchain/logs/process llvm test
-TODO
+ * `LLVM :: CodeGen/X86/mult-alt-generic-i686.ll`
+
+ This one, as well as a really large set of test from the test-suite fail on
+ coulomb.SCHWINGE no matter whether a GNU/Hurd or GNU/Linux system is booted
+ -- so all these are specific to the Athlon XP processor, hopefully.
+
+ * `Clang :: Index/crash-recovery-modules.m`
+
+ Also fails on GNU/Linux. Tested `--enable-optimized
+ --enable-expensive-checks --disable-threads --enable-debug-symbols
+ --enable-debug-runtime`. [[!LLVM_bug 11974]].
+
+ * `Clang :: Misc/dev-fd-fs.c`
+
+ $ cat < [...]/test/Misc/dev-fd-fs.c | Release+Debug+Asserts+Checks/bin/clang -x c /dev/fd/0 -E
+ clang: error: no such file or directory: '/dev/fd/0'
+ clang: error: no input files
+
+ Compare to:
+
+ $ cat < [...]/test/Misc/dev-fd-fs.c | gcc -x c /dev/fd/0 -E
+ gcc: error: /dev/fd/0: (ipc/mig) bad request message ID
+ gcc: warning: '-x c' after last input file has no effect
+ gcc: fatal error: no input files
+ compilation terminated.
+
+ These work:
+
+ $ Release+Debug+Asserts+Checks/bin/clang -x c /dev/fd/0 -E < [...]/test/Misc/dev-fd-fs.c
+ [...]
+ int x;
+ $ gcc -x c /dev/fd/0 -E < [...]/test/Misc/dev-fd-fs.c
+ [...]
+ int x;
+
+ * `Clang :: Tooling/clang-check-builtin-headers.cpp`
+
+ Fails: `fatal error: 'stddef.h' file not found`; succeeds when ran
+ manually.
+
+ * With `--enable-optimized --enable-expensive-checks --disable-threads
+ --enable-debug-symbols --enable-debug-runtime`, there are a few new FAILs
+ for both GNU/Linux and GNU/Hurd:
+
+ * `Clang :: Tooling/auto-detect-from-source-parent-of-cwd.cpp`
+
+ * `Clang :: Tooling/auto-detect-from-source-parent.cpp`
+
+ * `Clang :: Tooling/clang-check-autodetect-dir.cpp`
+
+ For all three, the `clang-check` invocation fails. [[!LLVM_bug 15194]].
+
+ * Several tests are not considered on GNU/Hurd.
