Hi,


I was thinking of applying the LLVM optimization passes in different order
to the generated .bc code of the OpenCL kernel to see how this will affect
the performance of the generated kernel. This will be tested on an AMD HSA
platform.



Should I do this after the .bc file is parsed in
pocl_update_program_llvm_irs()? Where is the best point in pocl for me to
do so?



BTW:



I couldn’t find the definition of the parseIRFile() function used in
pocl_llvm_api.c. Is this a LLVM API? I couldn‘t find it on the LLVM class
files either.



Cheers,

Zheng
