       lli - directly execute programs from LLVM bitcode


       lli [options] [filename] [program args]


       lli directly executes programs in LLVM bitcode format.  It takes a program in LLVM bitcode
       format and executes it using a just-in-time compiler, if one is available for the  current
       architecture,  or  an  interpreter.   lli  takes all of the same code generator options as
       llc|llc, but they are only effective when lli is using the just-in-time compiler.

       If filename is not specified, then lli  reads  the  LLVM  bitcode  for  the  program  from
       standard input.

       The optional args specified on the command line are passed to the program as arguments.


          Override the argv[0] value passed into the executing program.

          If  set  to  true, use the interpreter even if a just-in-time compiler is available for
          this architecture. Defaults to false.

          Print a summary of command line options.

          Causes lli to load the plugin (shared object)  named  pluginfilename  and  use  it  for

          Print  statistics  from  the  code-generation  passes.  This is only meaningful for the
          just-in-time compiler, at present.

          Record the amount of time needed for each code-generation pass and print it to standard

          Print out the version of lli and exit without doing anything else.


       -mtriple=target triple
          Override  the  target  triple  specified  in  the input bitcode file with the specified
          string.  This may result in a crash if you pick an architecture which is not compatible
          with the current system.

          Specify  the architecture for which to generate assembly, overriding the target encoded
          in the bitcode file.  See the output of llc -help for a list  of  valid  architectures.
          By  default  this  is  inferred  from  the target triple or autodetected to the current

          Specify a specific chip in the current architecture to generate code for.   By  default
          this  is  inferred from the target triple and autodetected to the current architecture.
          For a list of available CPUs, use: llvm-as < /dev/null | llc -march=xyz -mcpu=help

          Override or control specific attributes of the target, such as whether SIMD  operations
          are  enabled  or  not.  The default set of attributes is set by the current CPU.  For a
          list of available attributes, use: llvm-as < /dev/null | llc -march=xyz -mattr=help


          Disable optimizations that may increase floating point precision.

          Enable optimizations that assume no Inf values.

          Enable optimizations that assume no NAN values.

          Causes lli to enable optimizations that may decrease floating point precision.

          Causes lli to generate software floating point  library  calls  instead  of  equivalent
          hardware instructions.


          Choose the code model from:

              default: Target default code model
              small: Small code model
              kernel: Kernel code model
              medium: Medium code model
              large: Large code model

          Disable scheduling after register allocation.

          Disable fusing of spill code into instructions.

          Make the -lowerinvoke pass insert expensive, but correct, EH code.

          Exception handling should be enabled in the just-in-time compiler.

          Coalesce copies (default=true).

       -nozero-initialized-in-bss Don't place zero-initialized symbols into the BSS section.

          Instruction schedulers available (before register allocation):

              =default: Best scheduler for the target
              =none: No scheduling: breadth first sequencing
              =simple: Simple two pass scheduling: minimize critical path and maximize processor utilization
              =simple-noitin: Simple two pass scheduling: Same as simple except using generic latency
              =list-burr: Bottom-up register reduction list scheduling
              =list-tdrr: Top-down register reduction list scheduling
              =list-td: Top-down list scheduler -print-machineinstrs - Print generated machine code

          Register allocator to use (default=linearscan)

              =bigblock: Big-block register allocator
              =linearscan: linear scan register allocator =local -   local register allocator
              =simple: simple register allocator

          Choose relocation model from:

              =default: Target default relocation model
              =static: Non-relocatable code =pic -   Fully relocatable, position independent code
              =dynamic-no-pic: Relocatable external references, non-relocatable code

          Spiller to use (default=local)

              =simple: simple spiller
              =local: local spiller

          Choose style of code to emit from X86 backend:

              =att: Emit AT&T-style assembly
              =intel: Emit Intel-style assembly


       If lli fails to load the program, it will exit with an exit code of 1.  Otherwise, it will
       return the exit code of the program it executes.
