Controls the use of the Variable Length Encoded (VLE) instruction set.
-vle
This option tells the compiler and linker to generate and lay out Variable Length Encoded (VLE) instructions, available on Zen variants of Power Architecture processors. VLE instructions give extra flexibility in instruction encoding and alignment, allowing the compiler and linker to greatly reduce the size of runtime object code with only a small penalty in execution performance.
This option also turns on the -processor Zen option.
