3.17.5 C6X Options

-march=name

This specifies the name of the target architecture. GCC uses this name to determine what kind of instructions it can emit when generating assembly code. Permissible names are: `c62x', `c64x', `c64x+', `c67x', `c67x+', `c674x'.

-mbig-endian

Generate code for a big-endian target.

-mlittle-endian

Generate code for a little-endian target. This is the default.

-msim

Choose startup files and linker script suitable for the simulator.

-msdata=default

Put small global and static data in the `.neardata' section, which is pointed to by register B14. Put small uninitialized global and static data in the `.bss' section, which is adjacent to the `.neardata' section. Put small read-only data into the `.rodata' section. The corresponding sections used for large pieces of data are `.fardata', `.far' and `.const'.

-msdata=all

Put all data, not just small objets, into the sections reserved for small data, and use addressing relative to the B14 register to access them.

-msdata=none

Make no use of the sections reserved for small data, and use absolute addresses to access all data. Put all initialized global and static data in the `.fardata' section, and all uninitialized data in the `.far' section. Put all constant data into the `.const' section.
