-# WARNING: Use of OPTIMIZATION_LEVEL=HIGHEST in your Makefile needs to be
-# done with care, there are some assumptions below that need to
-# be understood about the use of pointers, and IEEE behavior.
-#
-# -fns: Use non-standard floating point mode (not IEEE 754)
-# -fsimple: Do some simplification of floating point arithmetic (not IEEE 754)
-# -fsingle: Use single precision floating point with 'float'
-# -xalias_level=basic: Assume memory references via basic pointer types do not alias
-# (Source with excessing pointer casting and data access with mixed
-# pointer types are not recommended)
-# -xbuiltin=%all: Use intrinsic or inline versions for math/std functions
-# (If you expect perfect errno behavior, do not use this)
-# -xdepend: Loop data dependency optimizations (need -xO3 or higher)
-# -xrestrict: Pointer parameters to functions do not overlap
-# (Similar to -xalias_level=basic usage, but less obvious sometimes.
-# If you pass in multiple pointers to the same data, do not use this)
-# -xlibmil: Inline some library routines
-# (If you expect perfect errno behavior, do not use this)
-# -xlibmopt: Use optimized math routines (CURRENTLY DISABLED)
-# (If you expect perfect errno behavior, do not use this)
-# Can cause undefined external on Solaris 8 X86 on __sincos, removing for now
