#### 9.9.3 Symbols

Some symbols are defined by the assembler. They’re intended to be used in conditional assembly, for example:

     .if ..asm.arch.cris.v32
     code for CRIS v32
     .elseif ..asm.arch.cris.common_v10_v32
     code common to CRIS v32 and CRIS v10
     .elseif ..asm.arch.cris.v10 | ..asm.arch.cris.any_v0_v10
     code for v10
     .else
     .error "Code needs to be added here."
     .endif

These symbols are defined in the assembler, reflecting command-line options, either when specified or the default. They are always defined, to 0 or 1.

`..asm.arch.cris.any_v0_v10`

  This symbol is non-zero when `--march=v0_v10` is specified or the default.

`..asm.arch.cris.common_v10_v32`

  Set according to the option `--march=common_v10_v32`.

`..asm.arch.cris.v10`

  Reflects the option `--march=v10`.

`..asm.arch.cris.v32`

  Corresponds to `--march=v10`.

Speaking of symbols, when a symbol is used in code, it can have a suffix modifying its value for use in position-independent code. See CRIS-Pic.
