LLVM-CGDATA(1) LLVM LLVM-CGDATA(1) NAME llvm-cgdata - LLVM CodeGen Data Tool SYNOPSIS llvm-cgdata [commands] [options] (<binaries>|<.cgdata>) DESCRIPTION The :program:llvm-cgdata utility parses raw codegen data embedded in compiled binary files and merges them into a single .cgdata file. It can also inspect and manipulate .cgdata files. Currently, the tool sup- ports saving and restoring outlined hash trees and stable function maps, allowing for more efficient function outlining and function merg- ing across modules in subsequent compilations. The design is extensi- ble, allowing for the incorporation of additional codegen summaries and optimization techniques. COMMANDS At least one of the following commands are required: --convert Convert a .cgdata file from one format to another. --merge Merge multiple raw codgen data in binaries into a single .cgdata file. --show Show summary information about a .cgdata file. OPTIONS llvm-cgdata supports the following options: --format=[text|binary] Specify the format of the output .cgdata file. --output=<string> Specify the output file name. --cgdata-version Print the version of the llvm-cgdata tool. EXAMPLES To convert a .cgdata file from binary to text format: $ llvm-cgdata --convert --format=text input.cgdata --output=out- put.data To merge multiple raw codegen data in object files into a single .cg- data file: $ llvm-cgdata --merge file1.o file2.o --output=merged.cgdata To show summary information about a .cgdata file: $ llvm-cgdata --show input.cgdata AUTHOR Maintained by the LLVM Team (https://llvm.org/).
