Hi,
I followed the instructions for building FPC with LLVM presented here [1].
Now I am interested in generating LLVM assembly from the corresponding
Pascal code. Is there any method to achieve this?
Just use -al option, this will leave the generated .ll file present after
compilation.
You can also use -vx option to see how clang is called:
