MIPS

    +
  • GCC can now generate code specifically for the R4700, Broadcom XLP + and MIPS 34kn processors. The associated -march options + are -march=r4700, -march=xlp + and -march=34kn respectively.
    • +
  • GCC now generates better DSP code for MIPS 74k cores thanks + to further scheduling optimizations.
    • +
  • The MIPS port now supports the -fstack-check + option.
  • GCC now passes the -mmcu and -mno-mcu - options to the assembler.
    • -
  • Support for the R4700 has been added.
    • -
  • GCC now generates better code for Broadcom XLP processors thanks - to improvements in scheduling and atomic built-ins support.
    • + options to the assembler. +
  • Previous versions of GCC would silently accept -fpic + and -fPIC for -mno-abicalls targets + like mips*-elf. This combination was not intended + or supported, and did not generate position-independent code. + GCC 4.8 now reports an error when this combination is used.
