llvm-diff – LLVM structural ‘diff’ Synopsisllvm-diff [options] module 1 module 2 [global name …] Descriptionllvm-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 be interpreted as…
llvm-cxxmap – Mangled name remapping tool Synopsisllvm-cxxmap [options] symbol-file-1 symbol-file-2 DescriptionThe 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 # are ignored….
llvm-cxxfilt – LLVM symbol name demangler Synopsisllvm-cxxfilt [options] [mangled names…] Descriptionllvm-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 simply printed as…
llvm-cov – emit coverage information Synopsisllvm-cov command [args…] DescriptionThe 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 behave as if…
llvm-config – Print LLVM compilation options Synopsisllvm-config option [components…] Descriptionllvm-config makes it easier to build applications that use LLVM. It can print the compiler flags, linker flags and object libraries needed to link against LLVM. ExamplesTo link against the JIT: g++ `llvm-config –cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp g++ `llvm-config –ldflags` -o HowToUseJIT HowToUseJIT.o \ `llvm-config…
