clang warns several times:

'enum siw_opcode' [-Wenum-conversion]

Weird that gcc doesn't warn on this by default..

Applied to for-next, thanks

Based on the sheer number of -Wenum-conversion that Nathan has fixed,
I don't think gcc has -Wenum-conversion (or it's somehow disabled just
for gcc).

Yes, as far as I am aware, GCC does not warn on implicit enum
conversions (which I think defeats the purpose of enumerated types
*shrugs*).

Nathan, thanks very much. That's correct.
I don't know how this could pass w/o warning.

Many thanks,
Bernard.

Thanks for the confirmation that the fix was correct.

Unfortunately, it appears that GCC only warns when two different
enumerated types are directly compared, not when they are implicitly
converted between.

https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wenum-compare

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78736

If it did, I wouldn't have fixed as many warnings as I have.

https://github.com/ClangBuiltLinux/linux/issues?q=is%3Aissue+is%3Aclosed+label%3A-Wenum-conversion

Maybe time to start plumbing Clang into your test flow until it can get
intergrated with more CI setups? :) It can catch some pretty dodgy
behavior that GCC doesn't:

https://github.com/ClangBuiltLinux/linux/issues/390

https://github.com/ClangBuiltLinux/linux/issues/544

Kernel CI has added support for it (although they don't email the
authors of patches individually) and 0day is currently working on it.
Feel free to reach out if you decide to explore it, I'm always happy
to help.

Cheers,
Nathan

I keep asking how to use clang to build the kernel and last I was told
it still wasn't ready..

Is it ready now? Is there some flow that will compile with clang
warning free, on any arch? (at least the portion of the kernel I check)

Well.. we didn't see any emails till yours, so if others are looking
they aren't communicating?

$ make CC=clang ...

You'll need clang-9 for x86 because of the asm-goto requirement (or a
selective set of reverts for clang-8) but everything else should be
good with clang-8:

https://travis-ci.com/ClangBuiltLinux/continuous-integration/builds/118745131

We wrote a Python script that builds an LLVM 9 toolchain suitable for
kernel development that is self contained (doesn't install anything to
your system):

https://github.com/ClangBuiltLinux/tc-build

Let me know if there are any issues with it if you give it a go, I've
already fixed one from Thomas Gleixner:

The latest clang-9 packages from apt.llvm.org do seem to build the
kernel, I get one puzzling warning under RDMA:

drivers/infiniband/hw/hfi1/platform.o: warning: objtool: tune_serdes()+0x1f4: can't find jump dest instruction at .text+0x118a

And a BPF one:

kernel/bpf/core.o: warning: objtool: ___bpf_prog_run()+0xd: sibling call from callable instruction with modified stack frame

Any particular config that I should use to easily reproduce this?

I think this might be related to this?

This is reproducible with the kernel config attached and a tip of tree
build of LLVM.

$ make -j$(nproc) CC=clang O=out clean olddefconfig drivers/infiniband/hw/hfi1/platform.o
...
  CC      drivers/infiniband/hw/hfi1/platform.o
drivers/infiniband/hw/hfi1/platform.o: warning: objtool: tune_serdes()+0x1f4: can't find jump dest instruction at .text+0x117a

I ran creduce on that file and it spits out:

a() {
  char *b = a;
  switch (b[7] & 240 >> 4) {
  case 10 ... 11:
    c();
  case 0 ... 9:
  case 12:
  case 14:
    d();
  case 13:
  case 15:;
  }
}

to simply reproduce the warning. The original preprocessed file +
interestingness test are available here:

https://github.com/nathanchance/creduce-files/tree/4e252c0ca19742c90be1445e6c722a43ae561144/rdma-objtool

Looks like that comes from tune_qsfp, which gets inlined into
tune_serdes but I am far from an objtool expert so I am not
really sure what kind of issues I am looking for. Adding Josh
and Peter for a little more visibility.

Here is the original .o file as well:

     574:       0f 87 00 0c 00 00       ja     117a <tune_serdes+0xdfa>

It's jumping to la-la-land past the end of the function.

Looks like a compiler bug.

Nathan,
Thanks for the reduced test case.  I modified it slightly:
https://godbolt.org/z/15xejg

You can see that the label LBB0_5 seemingly points off into space.
Let me play with this one more a bit, then I will file a bug and
report back.

Something funny going on in one of the earliest optimizations.  Seems
related to an analysis that's deducing that the case statement is
exhaustive (so the GNU C case range is unrelated), but it's keeping
the default case and its comparison around.  The analysis is correct;
the value should never be > 0xF so there shouldn't be any runtime
bugs, but this would avoid an unnecessary comparison for exhaustive
switch statements and save a few bytes of object code in such cases.
