Argh, GitHub runner limitations:

Run actions/checkout@v4
Error: JavaScript Actions in Alpine containers are only supported on x64 Linux runners. Detected Linux Arm64

kinke · 2025-06-06T12:12:35Z

A few failures, looking like exception backtraces are incomplete with optimized code (although the frame pointers are kept).

I am not sure this related, maybe try with apk add libunwind-dev

Thx, but that gives:

$ apk add libunwind-dev
ERROR: unable to select packages:
  libunwind-dev-1.8.1-r0:

I finally build the static binary and run the test:

ldc/tests/codegen/exception_stack_trace.d can be fix with printf("%.*s\n", cast(int) s.length, s.ptr);

Thx, but that gives:

$ apk add libunwind-dev
ERROR: unable to select packages:
  libunwind-dev-1.8.1-r0:
    breaks: llvm-libunwind-19.1.4-r1[!libunwind-dev]
    satisfies: world[libunwind-dev]

not sure how to fix this, but I guess maybe libunwind-dev not needed.

I checked my own static build of ldc2, and the official Alpine x86_64 release (v1.41.0) also lacks the --link-internally.

I guess lacks the --link-internally cause by lld20-dev can not be static linked.

ln -sf /usr/lib/llvm20/lib/LLVMgold.so /usr/lib/LLVMgold.so fix the LLVMgold.so. 2 tests error remain

I guess __sanitizer_acquire_crash_state test error cause by there is no libclang_rt.asan.a for alpine aarch64 until llvm22.

so maybe we need disable sanitizer for alpine aarch64 until we support llvm22 ?

calvin2021y · 2025-10-05T09:11:30Z

after disable lsan;asan;msan;fuzzer for TEST_COMPILER_RT_LIBRARIES, only 1 errortests/codegen/exception_stack_trace.d left for test-lit.

try apk add libunwind-static and apk add llvm-libunwind-static still failure.

musl seems to be sensitive to this on AArch64.

kinke · 2025-12-17T15:44:34Z

I've disabled the 4 failing tests for CI for now, seemingly all because of empty exception backtraces as soon as some optimized code is involved - I bet lit-test codegen/exception_stack_trace.d would work with -link-defaultlib-debug, as 2 backtrace-related DMD-testsuite tests and druntime-test-exceptions pass in their non-release variant, only failing in release.
