For this case, the 4k threshold is not eligible to determine it's a hybrid sample. This change renovated the `isHybridPerfScript` by going through the script without threshold limitation checking whether there is a non-empty call stack immediately followed by a LBR sample. It will stop once it find a valid one.2) Added several input validations for the command line switches in PerfReader.3) Changed the command line `show-disassembly` to `show-disassembly-only`, it will print to stdout and exit early which leave an empty output profile.Reviewed By: hoy, wenleiDifferential Revision: https://reviews.llvm.org/D96387 List of files: /llvm-project-15.0.7/llvm/test/tools/llvm-profgen/invalid-perfscript.test Wed, 10 Feb 2021 00:41:44 +0000 wlei <wlei@fb.com>
