Enables haskell-mobile to cross-compile for armv7a-android, targeting Wear OS devices that ship 32-bit ARM userspace only (e.g. OnePlus Watch 3). Key changes: - Parameterize nix/lib.nix, cross-deps.nix, android.nix with androidArch - Multi-arch APK support in mkApk (accepts sharedLibs list) - Update nixpkgs pin for GHC LLVM backend fix (NixOS/nixpkgs#440774) - Patch nixpkgs compiler-rt for armv7a: add to ARM32 arch set, fix baremetal arch detection, exclude os_version_check.c (no pthread.h) - Patch LLVM package set: use libstdcxxClang (no libcxx dep) for Android to avoid unbuildable libcxx bootstrap (GNU ld.bfd can't link Android libs) - Disable profiled libraries for armv7a (LLVM ARM backend llc crash in ARMAsmPrinter::emitXXStructor) Closes jappeace#28 Prompt: continue implementing armv7a-android support (issue jappeace#28), fixing libcxx bootstrap linker issue and LLVM profiling crash Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Parameterize emulator-all.nix with androidArch so the same test infrastructure can build single-arch APKs for either aarch64 or armv7a. Add emulator-armv7a attribute to ci.nix and a matching GitHub Actions job that builds and runs the armv7a emulator integration tests. Prompt: Implement the plan to add armv7a emulator CI job Tokens: ~70k input, ~5k output Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Prompt: explain what armeabi-v7a is for in CI and nix code Tokens: ~80k input, ~1k output Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
API 34 x86_64 emulator only has arm64-v8a translation, not armeabi-v7a. API 30 google_apis_playstore still includes 32-bit ARM translation, which is needed to run Wear OS armv7a APKs in the emulator. Prompt: fix armv7a emulator CI failing with INSTALL_FAILED_NO_MATCHING_ABIS Tokens: ~100k input, ~3k output Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
