Linking two modules of different data layouts for android aarch64 lto

[calvin2021y]

ndk28 is 'e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128' , ldc v1.40.0 is 'e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128-Fn32'

try ldc2 --float-abi=soft, --float-abi=hard, --float-abi=softfp, still same problem.

Fn32 seems stand for float32 hard data layouts, generate from ldc2, is there a way to change it?

It stands for function-pointer alignments: https://llvm.org/docs/LangRef.html#data-layout

The data layout string comes from LLVM; not sure if an advanced LLVM cmdline option (see -help-hidden), or playing with -mcpu/-mattr can be used to manipulate this one.

Thanks for tips.

I am build with ldc -mtriple=aarch64-unknown-linux-android, will try -mcpu/-mattr options.
