#### 3.17.6 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 objects, 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.
