+NAME +

+ +opt + +

+SYNOPSIS +

+ +opt [options] < filename> +

+DESCRIPTION +

+ +The opt command is the LLVM optimizer. It takes LLVM bytecode as input, runs +the specified optimizations on it, and then outputs the optimized code in LLVM +bytecode. + +The optimizations available via opt depend upon what libraries it was linked +with, as well as any additional libraries that have been loaded with the -load +option. Use the -help option to determine what optimizations you can use. + +

+OPTIONS +

+ +

-f +
+ Force overwrite. Normally, opt will refuse to overwrite an output + file that already exists. With this option, opt will overwrite the + output file and replace it with new bytecode. +
+ +
-help +
+ Print a summary of command line options. +
+ +
-o <filename> +
+ Specify the output filename. +
+ +
-stats +
+ Print statistics. +
+ +
-time-passes +
+ Record the amount of time needed for each pass and print it to standard + error. +
+ +
-internalize-public-api-file <filename> +
+ Preserve the symbol names listed in the file filename. +
+ +
-internalize-public-api-list=<list> +
+ Perserve the symbol names specified. +
+ +
-q +
+ Quiet mode. Do not print messages on whether the program was modified. +
+ +
-load <plugin.so> +
+ Load the dynamic object plugin.so. This object should register new + optimization passes. Once loaded, the object will add new command line + options to enable various optimizations. To see the new complete list + of optimizations, use the -help and -load options together: +
+ opt -load <plugin.so> -help +
+ +
-p +
+ Print module after each transformation. +
+

+ +

+EXIT STATUS +

+ +If opt succeeds, it will exit with 0. Otherwise, if an error occurs, it +will exit with a non-zero value. + +
