# -apo - auto-parallize for multiprocessors (implies -mp)

# strtoll, stroull etc.
# This option is vital to compile MySQL.

# -64 - generate 64 bit object (implies -mips4)
# -mips4 - produce code for MIPS R10000, MIPS R12000 and further 64 bit
# processors
# -OPT:Olimit=0 - no limits exists to size of function for compiler to optimize
