[lldb-dev] lldb-server stripped binary size: AArch64 ~16Mb vs ARM ~9 Mb

[Mikhail Filimonov via lldb-dev]

Hello, fellow developers and congratulations with long awaited 3.8 Release.

I wonder why AArch64 stripped binary of lldb-server built from [3.8 Release] RC3 source is so much bigger than its ARM counterpart.
See the numbers:
16318632 Feb 29 22:41 lldb-server-3.8.0-aarch64
 9570916 Feb 29 22:23 lldb-server-3.8.0-arm
lldb-server-3.8.0-aarch64: ELF 64-bit LSB  executable, ARM aarch64, version 1 (SYSV), statically linked, stripped
lldb-server-3.8.0-arm:     ELF 32-bit LSB  executable, ARM, EABI5 version 1 (SYSV), statically linked, stripped

My build configuration is MinSizeRel in both cases:
cmake -GNinja
-DCMAKE_BUILD_TYPE=MinSizeRel $HOME/llvm_git
-DCMAKE_TOOLCHAIN_FILE=tools/lldb/cmake/platforms/Android.cmake
-DANDROID_TOOLCHAIN_DIR=$HOME/Toolchains/aarch64-21-android
-DANDROID_ABI=aarch64
-DCMAKE_CXX_COMPILER_VERSION=4.9
-DLLVM_TARGET_ARCH=aarch64
-DLLVM_HOST_TRIPLE=aarch64-unknown-linux-android
-DLLVM_TABLEGEN=$HOME/llvm_host/bin/llvm-tblgen
-DCLANG_TABLEGEN=$HOME/llvm_host/bin/clang-tblgen

cmake -GNinja
-DCMAKE_BUILD_TYPE=MinSizeRel $HOME/llvm_git
-DCMAKE_TOOLCHAIN_FILE=tools/lldb/cmake/platforms/Android.cmake
-DANDROID_TOOLCHAIN_DIR=$HOME/Toolchains/arm-21-android-toolchain
-DANDROID_ABI=armeabi
-DCMAKE_CXX_COMPILER_VERSION=4.9
-DLLVM_TARGET_ARCH=arm
-DLLVM_HOST_TRIPLE=arm-unknown-linux-android
-DLLVM_TABLEGEN=$HOME/llvm_host/bin/llvm-tblgen
-DCLANG_TABLEGEN=$HOME/llvm_host/bin/clang-tblgen

Maybe I need some additional settings to be set for AArch64 case?

Regards,
Mikhail

Dear testers,

Release Candidate 3 has just been tagged [1]. Please build, test, and upload to the sftp.

If there are no regressions from previous release candidates, this will be the last release candidate before the final release.

Release notes can still go into the branch.

Thanks again for all your work!
Hans
