The CGProfilePass needs to be run during FullLTO compilation at link time to emit the .llvm.call-graph-profile section to the compiled LTO object file. Currently, it is being run only during the initial LTO-prelink compilation stage (to produce the bitcode files to be consumed by the linker) and so the section is not produced. ThinLTO is not affected because: - For ThinLTO-prelink compilation the CGProfilePass pass is not run because ThinLTO-prelink passes are added via buildThinLTOPreLinkDefaultPipeline. Normal and FullLTO-prelink passes are both added via buildPerModuleDefaultPipeline which uses the LTOPreLink parameter to customize its behavior for the FullLTO-prelink pass differences. - ThinLTO backend compilation phase adds the CGProfilePass (see: buildModuleOptimizationPipeline). Adjust when the pass is run so that the .llvm.call-graph-profile section is produced correctly for FullLTO. Fixes #56185 (https://github.com/llvm/llvm-project/issues/56185)
