In an effort to test out the latest version of Clang -- for supposedly
increased performance and less crashes --, I've checked out and compiled a
recent version Clang/LLVM (recompiled it with itself), compiled a new kernel
and world using WITHOUT_GCC=1 and WITHOUT_CLANG=1, installed them, removed
(almost) all remnants of the base GCC and base Clang binaries
(/usr/{libexec/cc1{|plus}|bin/c{c|pp|++|++filt|89|99}} -- that ``make
delete-old'' did not remove!) (keeping only the latest Clang installation), and
recompiled the kernel and world again. This whole process was very annoying,
not only due to compilation errors, but also due to makefile-related workings
that I learned via the hard way.
I'll describe the errors I've encountered, along with some workarounds I used
to get the compiling process to move on. I've also looked at the compiler
warnings, and noticed some frightening/valid ones. I expect committers to do
something about both the errors and, where appropriate, the warnings (which
perhaps means telling me what I did WRONG).
It was difficult to properly keep a record of all errors. That doesn't matter
much anyway, as I will re-test often to see if there are any errors and
suspicious warnings remaining.
Note that I haven't even begun testing portbuilding on this base-compiler-free
setup.
Logs are prefixed with ``* ''. Only slimmed logs are be posted here (fuller
logs, including invocation, etc. will be posted in a subsequent e-mail upon
request).
First come the compilation errors.

This can be fixed by adding a CC environment variable: In
usr.bin/xlint/llib/Makefile, change
${LINT} ${LINTFLAGS} -Cposix ${.ALLSRC}
to
CC=${CC:Q} ${LINT} ${LINTFLAGS} -Cposix ${.ALLSRC}
With this, linting proceeds:
* stdarg.h(30): syntax error [249]
* llib-lposix(307): syntax error [249]
* llib-lposix(308): syntax error [249]
* llib-lposix(309): syntax error [249]
Also, the same execution error, fix, and linting error applies to llib-lstdc
instead of llib-lposix as well.
A crappy workaround patch for the incompatibilities (or whatever) is at the end
of this e-mail.

During ``make installworld'':
* btxld: Command not found.
I had to append not only ``btxld'', but also ``ls dd cp'', to the ITOOLS
variable in Makefile.inc1.
On a side-note, around this point I found out that the CC setting in
/etc/make.conf should be absolute, instead of having the compiler in the PATH
of the user's shell. I also find it WRONG that there is some compilation going
on during ``make installworld''.
And now, here come the warnings. Some (all?) of these should have been errors,
but Clang was instructed to ignore these.
