This patch implements the following floating point negative absolute value builtins that required for compatibility with the XL compiler: ``` double __fnabs(double); float __fnabss(float); ``` These builtins will emit : - fnabs on PWR6 and below, or if VSX is disabled. - xsnabsdp on PWR7 and above, if VSX is enabled.
