Hey all, having a hell of a time trying to build the static libSwiftDemangle.a framework to build for both arm64 and x86_64. I can build it just fine for x86_64, but ARM64 has been a major PitA
What I've done:
update-checkout --clone-with-ssh --tag swift-5.1.4-RELEASE
And tried to compile with various permutations leading up to this monstrosity:
build-script --maccatalyst=1 --stdlib-deployment-targets="iphoneos-arm64" --build-stdlib-deployment-targets="iphoneos-arm64" -r --skip-test-ios=1 --skip-test-ios-32bit-simulator=1 --llvm-targets-to-build="AArch64;X86" --skip-build-watchos=1 --skip-build-tvos=1 --skip-build-linux=1 --skip-build-benchmarks=1 --skip-test-playgroundsupport=1 --skip-build-cygwin=1 --skip-build-freebsd=1 --build-swift-static-sdk-overlay=1 --build-swift-static-stdlib=1 -i --skip-build-ios-simulator=1 --cross-compile-hosts="iphoneos-arm64" --llvm-targets-to-build="X86;AArch64"
Which then will eventually give me these errors:

I've tried so many different permutations wanting to compile swift for an
iphoneos-arm64target (specifically the libSwiftDemangle.a static lib), but I am at the point where I need help. What's the best or fastest way to do this? Do I need to modify the CMakeLists.txt? Do I need to add some missing arguments so LLVM can play nice? -
The libSwiftDemangle.a source code can be found in
swift-source/libdirectory. I am wondering what subcomponent of Swift will build all these components in this directory. For example, in thebuild-scriptdocumentation I see all these compile options for stdlib, which I can assume correlates toswift-source/stdlibfiles, but what compile name correlates to thelibdirectory?
