#### 8.34.1 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 a separate section 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.
`--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. See Automatic Instruction 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. See Function 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.
