5.7.1.14 Long-calls Option

The -mlong-calls option disables the use of the jal instruction. Calling functions using this instruction is more efficient but requires the caller and callee functions to be in the same 256 megabyte segment. This option has no effect on abicalls code.

The -mno-long-calls form of this option allows the use of jal instructions. This is the default action if no option is specified.
