Enable (only) instructions from architecture arch. By default, all instructions are permitted.

The following values of arch are accepted: c62x, c64x, c64x+, c67x, c67x+, c674x.

The -mdsbt option causes the assembler to generate the Tag_ABI_DSBT attribute with a value of 1, indicating that the code is using DSBT addressing. The -mno-dsbt option, the default, causes the tag to have a value of 0, indicating that the code does not use DSBT addressing. The linker will emit a warning if objects of different type (DSBT and non-DSBT) are linked together.

The -mpid= option causes the assembler to generate the Tag_ABI_PID attribute with a value indicating the form of data addressing used by the code. -mpid=no, the default, indicates position-dependent data addressing, -mpid=near indicates position-independent addressing with GOT accesses using near DP addressing, and -mpid=far indicates position-independent addressing with GOT accesses using far DP addressing. The linker will emit a warning if objects built with different settings of this option are linked together.

The -mpic option causes the assembler to generate the Tag_ABI_PIC attribute with a value of 1, indicating that the code is using position-independent code addressing, The -mno-pic option, the default, causes the tag to have a value of 0, indicating position-dependent code addressing. The linker will emit a warning if objects of different type (position-dependent and position-independent) are linked together.
