The linux perf tools use /proc/kcore for disassembly kernel functions. Actually it copies the relevant parts to a temp file and then pass it to objdump. But it doesn't have section headers so llvm-objdump cannot handle it. Let's create fake section headers for the program headers. It'd have a single section for each segment to cover the entire range. And for this purpose we can consider only executable code segments. With this change, I can see the following command shows proper outputs. perf annotate --stdio --objdump=/path/to/llvm-objdump Differential Revision: https://reviews.llvm.org/D128705
