-// rb_ia64_flushrs and rb_ia64_bsp is written in IA64 assembly language
-// because Intel Compiler for IA64 doesn't support inline assembly.
-//
-// This file is based on following C program compiled by gcc.
-//
-// void rb_ia64_flushrs(void) { __builtin_ia64_flushrs(); }
-// void *rb_ia64_bsp(void) { return __builtin_ia64_bsp(); }
-//
-// Note that rb_ia64_flushrs and rb_ia64_bsp works in its own stack frame.
-// It's because BSP is updated by br.call/brl.call (not alloc instruction).
-// So rb_ia64_flushrs flushes stack frames including caller's one.
-// rb_ia64_bsp returns the address next to caller's register stack frame.
-//
-// See also
-// Intel Itanium Architecture Software Developer's Manual
-// Volume 2: System Architecture.
