[Issue]: Disassemble Flang Openmp Offloading #1119

Open Luigi-Crisci opened 1 month ago

Luigi-Crisci commented 1 month ago

Problem Description

Hi, This is more of a question than an issue. Is there a way to disassemble the generated amdcgn code when compiling a fortran openmp program with target directives? Currently, I am doing a kind of trick: generating the assembly with -S and then manually extracting the amdcgn from the .Lllvm.embedded.object string inside.

Operating System

Ubuntu 22.04

CPU

AMD EPYC 9654 96-Core Processor

Hi @Luigi-Crisci, you can also get the assembly by adding the -save-temps flag to save intermediate compilation results and look for *-openmp-amdgcn-amd-amdhsa.s file. It will contain more information than just the kernel assembly. Hope it helps.
