Hi all,
I am currently working on building OpenSSL for RISC-V architecture using clang/llvm. While I've successfully compiled OpenSSL and generated a binary using the linux64-riscv64 configuration, I would like to integrate an LLVM optimization pass into the compilation process before the object files are created.
Traditionally, the OpenSSL process follows the pattern:
clang [source file] -o [obj file]
However, my objective is to introduce an additional step in the process, as follows:
clang [source file] -o [LLVM IR File]
opt [LLVM IR File] -o [OPTIMIZED LLVM IR File]
clang [OPTIMIZED LLVM IR File] -o [obj file]
Basically, I want to create intermediate representations (IR), apply a custom optimization pass on them, and subsequently produce an object file on all the source files.
Could I please get some guidance or point me in the right direction on how to achieve this within the OpenSSL build process?
Your assistance would be greatly appreciated.
