.. 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. -fake-argv0=executable NDENT 0.0 NDENT 3.5 Override the argv[0] value passed into the executing program. NINDENT NINDENT -force-interpreter={false,true} NDENT 0.0 NDENT 3.5 If set to true, use the interpreter even if a just-in-time compiler is available for this architecture. Defaults to false. NINDENT NINDENT -help NDENT 0.0 NDENT 3.5 Print a summary of command line options. NINDENT NINDENT -load=pluginfilename NDENT 0.0 NDENT 3.5 Causes lli to load the plugin (shared object) named pluginfilename and use it for optimization. NINDENT NINDENT -stats NDENT 0.0 NDENT 3.5 Print statistics from the code-generation passes. This is only meaningful for the just-in-time compiler, at present. NINDENT NINDENT -time-passes NDENT 0.0 NDENT 3.5 Record the amount of time needed for each code-generation pass and print it to standard error. NINDENT NINDENT -version NDENT 0.0 NDENT 3.5 Print out the version of lli and exit without doing anything else. NINDENT NINDENT -mtriple=target triple NDENT 0.0 NDENT 3.5 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. NINDENT NINDENT -march=arch NDENT 0.0 NDENT 3.5 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 architecture. NINDENT NINDENT -mcpu=cpuname NDENT 0.0 NDENT 3.5 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 NINDENT NINDENT -mattr=a1,+a2,-a3,... NDENT 0.0 NDENT 3.5 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 NINDENT NINDENT -disable-excess-fp-precision NDENT 0.0 NDENT 3.5 Disable optimizations that may increase floating point precision. NINDENT NINDENT -enable-no-infs-fp-math NDENT 0.0 NDENT 3.5 Enable optimizations that assume no Inf values. NINDENT NINDENT -enable-no-nans-fp-math NDENT 0.0 NDENT 3.5 Enable optimizations that assume no NAN values. NINDENT NINDENT -enable-unsafe-fp-math NDENT 0.0 NDENT 3.5 Causes lli to enable optimizations that may decrease floating point precision. NINDENT NINDENT -soft-float NDENT 0.0 NDENT 3.5 Causes lli to generate software floating point library calls instead of equivalent hardware instructions. NINDENT NINDENT -code-model=model NDENT 0.0 NDENT 3.5 Choose the code model from: NDENT 0.0 NDENT 3.5

default: Target default code model

NINDENT NINDENT NINDENT NINDENT -disable-post-RA-scheduler NDENT 0.0 NDENT 3.5 Disable scheduling after register allocation. NINDENT NINDENT -disable-spill-fusing NDENT 0.0 NDENT 3.5 Disable fusing of spill code into instructions. NINDENT NINDENT -enable-correct-eh-support NDENT 0.0 NDENT 3.5 Make the -lowerinvoke pass insert expensive, but correct, EH code. NINDENT NINDENT -jit-enable-eh NDENT 0.0 NDENT 3.5 Exception handling should be enabled in the just-in-time compiler. NINDENT NINDENT -join-liveintervals NDENT 0.0 NDENT 3.5 Coalesce copies (default=true). NINDENT NINDENT -nozero-initialized-in-bss Don\(aqt place zero-initialized symbols into the BSS section. -pre-RA-sched=scheduler NDENT 0.0 NDENT 3.5 Instruction schedulers available (before register allocation): NDENT 0.0 NDENT 3.5

NINDENT NINDENT NINDENT NINDENT 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. llc|llc Maintained by The LLVM Team (http://llvm.org/). 2003-2013, LLVM Project Generated by docutils manpage writer.
