link error in release mode

[dingiso]

Hi brett

I have tried to build stf_lib for riscv-perf-model in release mode and encountered an error

ltf_lib/lib/libstf.a: error adding symbols: file format not recognized
clang: error: linker command failed with exit code 1 (use -v to see invocation)

But it disappeared when compile using debug mode

These are my cmake, clang and linker versions

clang version 10.0.0-4ubuntu1
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

❯ ld --version
GNU ld (GNU Binutils for Ubuntu) 2.34
Copyright (C) 2020 Free Software Foundation, Inc.

❯ cmake --version
cmake version 3.25.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

May have a look at the optimization or something else 😸 ？

Thanks,
Dingisoul

Can you give me more information about your build environment and which riscv-perf-model git SHA you're using? One thing to double check is that you aren't re-running a build with a different compiler (i.e., started a build with gcc, killed it, then re-ran with clang).
