-/* The PLT stubs will call _dl_runtime_resolve/_dl_runtime_profile
- * with the following linkage:
- *   r2 - r6 : parameter registers
- *   f0, f2, f4, f6 : floating point parameter registers
- *   24(r15), 28(r15) : PLT arguments PLT1, PLT2
- *   96(r15) : additional stack parameters
- * The normal clobber rules for function calls apply:
- *   r0 - r5 : call clobbered
- *   r6 - r13 :	 call saved
- *   r14 : return address (call clobbered)
- *   r15 : stack pointer (call saved)
- *   f1, f3, f5, f7 : call saved
- *   f0 - f3, f5, f7 - f15 : call clobbered
