/* Generated by script/gen-inject-asm.sh. The relevant source is in-tree (make
* out/darwin-inject-asm.S), but this file has been checked in too, in case
* your C compiler doesn't support all of these architectures.
* This file contains code for 4 architectures in one text page; it's remapped
* into the target process and the appropriate thunk executed. Having ARM code
* here on x86 and whatnot is currently pointless (and use of that code is
* disabled in case any future Rosetta-like emulator breaks naive attempts to
* inject into foreign-architecture processes), but we need two architectures
* anyway, so the rest are included in case doing so is useful someday. */
