NAME llvm-lib – LLVM lib.exe compatible library tool SYNOPSIS llvm-lib [/libpath:<path>] [/out:<output>] [/llvmlibthin] [/ignore] [/machine] [/nologo] [files…] DESCRIPTION The llvm-lib command is intended to be a lib.exe compatible tool. See https://msdn.microsoft.com/en-us/library/7ykb2k5f for the general description. llvm-lib has the following extensions: • Bitcode files in symbol tables. llvm-lib includes symbols from both bitcode files and regular…
NAME llvm-ld – LLVM linker SYNOPSIS llvm-ld <options> <files> DESCRIPTION The llvm-ld tool takes a set of LLVM bitcode files and links them together into a single LLVM bitcode file. The output bitcode file can be another bitcode file or an executable bitcode program. Using additional options, llvm-ld is able to produce native code executables….
NAME llvm-install-name-tool – LLVM tool for manipulating install-names and rpaths SYNOPSIS llvm-install-name-tool [options] input DESCRIPTION llvm-install-name-tool is a tool to manipulate dynamic shared library install names and rpaths listed in a Mach-O binary. For most scenarios, it works as a drop-in replacement for Apple’s install_name_tool. OPTIONS At least one of the following options are required,…
NAME llvm-extract – extract a function from an LLVM module SYNOPSIS llvm-extract [options] –func function-name [filename] DESCRIPTION The llvm-extract command takes the name of a function and extracts it from the specified LLVM bitcode file. It is primarily used as a debugging tool to reduce test cases from larger programs that are triggering a bug….

It is primarily used as a debugging tool to reduce test cases from larger programs that are triggering a bug….
NAME llvm-exegesis – LLVM Machine Instruction Benchmark SYNOPSIS llvm-exegesis [options] DESCRIPTION llvm-exegesis is a benchmarking tool that uses information available in LLVM to measure host machine instruction characteristics like latency, throughput, or port decomposition. Given an LLVM opcode name and a benchmarking mode, llvm-exegesis generates a code snippet that makes execution as serial (resp. as…
NAME llvm-dwarfdump – manual page for llvm-dwarfdump 9 DESCRIPTION OVERVIEW: pretty-print DWARF debug information in object files and debug info archives. USAGE: llvm-dwarfdump [options] <input object files or .dSYM bundles> OPTIONS: Color Options: –color – Use colors in output (default=autodetect) Generic Options: –help – Display available options (–help-hidden for more) –help-list – Display list of…
NAME llvm-dwarfdump – manual page for llvm-dwarfdump 14 DESCRIPTION OVERVIEW: pretty-print DWARF debug information in object files and debug info archives.

NAME llvm-dis – LLVM disassembler SYNOPSIS llvm-dis [options] [filename] DESCRIPTION The llvm-dis command is the LLVM disassembler. It takes an LLVM bitcode file and converts it into human-readable LLVM assembly language. If filename is omitted or specified as "-", llvm-dis reads its input from standard input. If the input is being read from standard input,…
NAME llvm-dis – LLVM disassembler SYNOPSIS llvm-dis [options] [filename] DESCRIPTION The llvm-dis command is the LLVM disassembler. It takes an LLVM bitcode file and converts it into human-readable LLVM assembly language. If filename is omitted or specified as –, llvm-dis reads its input from standard input. If the input is being read from standard input,…
NAME llvm-diff – LLVM structural ‘diff’ SYNOPSIS llvm-diff [options] module 1 module 2 [global name …] DESCRIPTION llvm-diff compares the structure of two LLVM modules, primarily focusing on differences in function definitions. Insignificant differences, such as changes in the ordering of globals or in the names of local values, are ignored. An input module will…
NAME llvm-cxxmap – Mangled name remapping tool SYNOPSIS llvm-cxxmap [options] symbol-file-1 symbol-file-2 DESCRIPTION The llvm-cxxmap tool performs fuzzy matching of C++ mangled names, based on a file describing name components that should be considered equivalent. The symbol files should contain a list of C++ mangled names (one per line). Blank lines and lines starting with…
NAME llvm-cxxfilt – LLVM symbol name demangler SYNOPSIS llvm-cxxfilt [options] [mangled names…] DESCRIPTION llvm-cxxfilt is a symbol demangler that can be used as a replacement for the GNU c++filt tool. It takes a series of symbol names and prints their demangled form on the standard output stream. If a name cannot be demangled, it is…
NAME llvm-cov – emit coverage information SYNOPSIS llvm-cov command [args…] DESCRIPTION The llvm-cov tool shows code coverage information for programs that are instrumented to emit profile data. It can be used to work with gcov-style coverage or with clang‘s instrumentation based profiling. If the program is invoked with a base name of gcov, it will…
NAME llvm-config – Print LLVM compilation options SYNOPSIS llvm-config option [components…] DESCRIPTION llvm-config makes it easier to build applications that use LLVM.
