#### 9.7.3 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.
