NAME llvm-objcopy – object copying and editing tool SYNOPSIS llvm-objcopy [options] input [output] DESCRIPTION llvm-objcopy is a tool to copy and manipulate objects. In basic usage, it makes a semantic copy of the input to the output. If any options are specified, the output may be modified along the way, e.g. by removing sections. If…

NAME llvm-nm – list LLVM bitcode file’s symbol table SYNOPSIS llvm-nm [options] [filenames…] DESCRIPTION The llvm-nm utility lists the names of symbols from the LLVM bitcode files, or ar archives containing LLVM bitcode files, named on the command line. Each symbol is listed along with some simple information about its provenance. If no file name…

NAME llvm-nm – list LLVM bitcode and object file’s symbol table SYNOPSIS llvm-nm [options] [filenames…] DESCRIPTION The llvm-nm utility lists the names of symbols from LLVM bitcode files, object files, and archives. Each symbol is listed along with some simple information about its provenance. If no filename is specified, a.out is used as the input….

NAME llvm-mca – LLVM Machine Code Analyzer SYNOPSIS llvm-mca [options] [input] DESCRIPTION llvm-mca is a performance analysis tool that uses information available in LLVM (e.g. scheduling models) to statically measure the performance of machine code in a specific CPU. Performance is measured in terms of throughput as well as processor resource consumption. The tool currently…
