llvm [1] llvm outline

llvm bundle outline [llvm1]

• bugpoint

    bugpoint is used to debug optimization passes or code generation 
    backends by narrowing down the given test case to the minimum number
    of passes and/or instructions that still cause a problem, whether it 
    is a crash or miscompilation. 
  

• llvm-ar

    The archiver produces an archive containing the given LLVM bitcode 
    files, optionally with an index for faster lookup.
  

• llvm-as

    The assembler transforms the human readable LLVM assembly to LLVM 
    bitcode.
  

• llvm-dis

    The disassembler transforms the LLVM bitcode to human readable LLVM 
    assembly.
  

• llvm-link

    llvm-link, not surprisingly, links multiple LLVM modules into a 
    single program.
  

• lli

    lli is the LLVM interpreter, which can directly execute LLVM bitcode 
    (although very slowly...). For architectures that support it 
    (currently x86, Sparc, and PowerPC), by default, lli will function as 
    a Just-In-Time compiler (if the functionality was compiled in), and 
    will execute the code much faster than the interpreter.
  

• llc

    llc is the LLVM backend compiler, which translates LLVM bitcode to a 
    native code assembly file or to C code (with the -march=c option).
  

• opt

    opt reads LLVM bitcode, applies a series of LLVM to LLVM 
    transformations (which are specified on the command line), and then 
    outputs the resultant bitcode. The ‘opt -help‘ command is a good way 
    to get a list of the program transformations available in LLVM.
  
    opt can also be used to run a specific analysis on an input LLVM 
    bitcode file and print out the results. It is primarily useful for 
    debugging analyses, or familiarizing yourself with what an analysis 
    does.
  

• llvm-config

    llvm-config can print the compiler flags, linker flags and object 
    libraries needed to link against llvm.
