9.31.1 Options

Replace identified out-of-range branches with PC-relative jmp sequences when possible. The generated code sequences are suitable for use in position-independent code, but there is a practical limit on the extended branch range because of the length of the sequences. This option is the default.

Replace branch instructions not determinable to be in range and all call instructions with jmp and callr sequences (respectively). This option generates absolute relocations against the target symbols and is not appropriate for position-independent code.

Do not replace any branches or calls.

Generate big-endian output.

Generate little-endian output. This is the default.

-march= architecture
This option specifies the target architecture. The assembler issues an error message if an attempt is made to assemble an instruction which will not execute on the target architecture. The following architecture names are recognized: r1 , r2 . The default is r1 .
