(as.info.gz) Xtensa Options

 
 9.40.1 Command Line Options
 ---------------------------
 
 The Xtensa version of the GNU assembler supports these special options:
 
 `--text-section-literals | --no-text-section-literals'
      Control the treatment of literal pools.  The default is
      `--no-text-section-literals', which places literals in separate
      sections in the output file.  This allows the literal pool to be
      placed in a data RAM/ROM.  With `--text-section-literals', the
      literals are interspersed in the text section in order to keep
      them as close as possible to their references.  This may be
      necessary for large assembly files, where the literals would
      otherwise be out of range of the `L32R' instructions in the text
      section.  These options only affect literals referenced via
      PC-relative `L32R' instructions; literals for absolute mode `L32R'
      instructions are handled separately.   literal Literal
      Directive.
 
 `--absolute-literals | --no-absolute-literals'
      Indicate to the assembler whether `L32R' instructions use absolute
      or PC-relative addressing.  If the processor includes the absolute
      addressing option, the default is to use absolute `L32R'
      relocations.  Otherwise, only the PC-relative `L32R' relocations
      can be used.
 
 `--target-align | --no-target-align'
      Enable or disable automatic alignment to reduce branch penalties
      at some expense in code size.   Automatic Instruction
      Alignment Xtensa Automatic Alignment.  This optimization is
      enabled by default.  Note that the assembler will always align
      instructions like `LOOP' that have fixed alignment requirements.
 
 `--longcalls | --no-longcalls'
      Enable or disable transformation of call instructions to allow
      calls across a greater range of addresses.   Function Call
      Relaxation Xtensa Call Relaxation.  This option should be used
      when call targets can potentially be out of range.  It may degrade
      both code size and performance, but the linker can generally
      optimize away the unnecessary overhead when a call ends up within
      range.  The default is `--no-longcalls'.
 
 `--transform | --no-transform'
      Enable or disable all assembler transformations of Xtensa
      instructions, including both relaxation and optimization.  The
      default is `--transform'; `--no-transform' should only be used in
      the rare cases when the instructions must be exactly as specified
      in the assembly source.  Using `--no-transform' causes out of range
      instruction operands to be errors.
 
 `--rename-section OLDNAME=NEWNAME'
      Rename the OLDNAME section to NEWNAME.  This option can be used
      multiple times to rename multiple sections.
