Today I checked in a pass-5 test of the relatively new *_arg(n)
functions. These functions provide access to a probed function's args
by number (e.g., for dwarfless probing) rather than by name. This test
should pass on powerpc*, i386, and x86_64; but should fail on
architectures that haven't implemented these functions.
The functions are described in stapfuncs.5.in, and are implemented (so
far) in tapset/$arch/registers.stp -- with some help from
runtime/regs.c.
