[LLVMdev] RFC: Instrumentation based profiling file libraries
The frontend-driven instrumentation based profiling used for clang's -fprofile-instr-generate and -fprofile-instr-use currently has logic for handling its data format spread about a few different places: 1. Reading files is done in clang when -fprofile-instr-use is specified. The logic is in CodeGen/CodeGenPGO.cpp. 2. Reading files is done by the (very preliminary) llvm-profdata tool,

[LLVMdev] RFC: Binary format for instrumentation based profiling data
...s a proposal for the instrumentation-based approach that I talked about at the dev meeting. I don’t see how it can share the a file format with the sample profiler, since the content is fundamentally different. > > I think we should be able to use the same pass in > lib/Transforms/Scalar/SampleProfile.cpp to read profiles generated > from instrumentation.

The information is completely different.
