15.0.7 runtime build fails on armv7l with missing unwinder

[ilg-ul]

I'm maintaining a multi-platform binary distribution (https://github.com/xpack-dev-tools/clang-xpack/) and when I tried to build the latest release I noticed the 32-bit arm build failed (and it was not due to low memory, as feared...).

To exclude issues with my configuration and build environment, I did a separate build with a simple configuration on a clean machine and the build failed too.

The commands used were:

mkdir -pv ~/Work/llvm-test/sources
curl -L https://github.com/llvm/llvm-project/releases/download/llvmorg-15.0.7/llvm-project-15.0.7.src.tar.xz -o ~/Work/llvm-test/sources/llvm-project-15.0.7.src.tar.xz

tar xf ~/Work/llvm-test/sources/llvm-project-15.0.7.src.tar.xz -C ~/Work/llvm-test/sources

mkdir -pv ~/Work/llvm-test/build
mkdir -pv ~/Work/llvm-test/install

# Minimal configuration that matches my needs.

cmake \
  --build "${HOME}/Work/llvm-test/build" \
  --verbose

The build failed while making the runtime, due to the missing unwinder library:

The machine used was a Raspberry Pi OS 32-bit.

I kept the entire build environment, and I also have a build with the same configuration on an aarch64 machine (Raspberry Pi OS 64-bit) which passed, so we can use it as a reference.

Any similar experience? I would appreciate any suggestions how to fix this.

I see a lot of linker errors, probably the system linker is not up to the task:

/usr/bin/ld: /usr/bin/ld: DWARF error: invalid or unhandled FORM value: 0x25

The linker is 2.35.2:

$ /usr/bin/ld --version
GNU ld (GNU Binutils for Raspbian) 2.35.2

[Naville]

https://sourceware.org/bugzilla/show_bug.cgi?id=27521 This?

LLVM states:

GNU ld 2.16.X. Some 2.16.X versions of the ld linker will produce very long warning messages complaining that some “.gnu.linkonce.t.*” symbol was defined in a discarded section. You can safely ignore these messages as they are erroneous and the linkage is correct. These messages disappear using ld 2.17.

GNU binutils 2.17: Binutils 2.17 contains [a bug](http://sourceware.org/bugzilla/show_bug.cgi?id=3111) which causes huge link times (minutes instead of seconds) when building LLVM. We recommend upgrading to a newer version (2.17.50.0.4 or later).

GNU Binutils 2.19.1 Gold: This version of Gold contained [a bug](http://sourceware.org/bugzilla/show_bug.cgi?id=9836) which causes intermittent failures when building LLVM with position independent code. The symptom is an error about cyclic dependencies. We recommend upgrading to a newer version of Gold.

The DWARF error seems to be the same, but I'm not sure that the undefined references are caused by it.

The linker line explicitly asks for --unwindlib=none, yet there are still references to the unwinder.

[ilg-ul]

I checked and in my production build environment I use gcc 12 & binutils 2.39; I don't see the DWARF error, but the arm 32-bit build of the runtime still fails, so I would not exclude other problems than binutils yet.

[ilg-ul]

I found this commit that changes some details of runtime builds:

• a8cd939#diff-512f2f05a3670932a0fe3a22f9cdbea21022856290b41ee858554cc6212d2187

There is also a comment mentioning a reorder of the runtimes, to fix some dependency issues, with compiler-rt moved to the end of the list; I find this weird, since in those files there are other comments mentioning --unwindlib=none.

I tried a new build with a different order in LLVM_ENABLE_RUNTIMES, but it did not fix the problem...

[DavidSpickett]

We (Linaro) saw this previously with scudo - #56900

And I have hit it with GWPASAN like you have, but applying the same sort of change didn't fix anything. At this time I don't understand exactly how the fix for scudo worked.

Hi David @DavidSpickett, thank you for confirming this bug.

I'll postpone my 15.x release and stick to 14.x till the problem is identified and fixed.

[ilg-ul]

Do we know of other Linux 32-bit arm distributions which include llvm/clang 15, to check if they applied any patches?
