gcc: FR-V Built-in Functions

1 
1 6.59.12 FR-V Built-in Functions
1 -------------------------------
1 
1 GCC provides many FR-V-specific built-in functions.  In general, these
1 functions are intended to be compatible with those described by 'FR-V
1 Family, Softune C/C++ Compiler Manual (V6), Fujitsu Semiconductor'.  The
1 two exceptions are '__MDUNPACKH' and '__MBTOHE', the GCC forms of which
1 pass 128-bit values by pointer rather than by value.
1 
1  Most of the functions are named after specific FR-V instructions.  Such
1 functions are said to be "directly mapped" and are summarized here in
1 tabular form.
