It is\noff when compiling to memory.\n\nTo switch this off in dex2oat, use the command line option:\n--no-helper-trampolines\n\nEnhances disassembler to print the trampoline entry on the\nBL instruction like this:\n\n0xb6a850c0: f7ffff9e  bl      -196 (0xb6a85000)  ; pTestSuspend\n\nBug: 12607709\nChange-Id: I9202bdb7cf21252ad807bd48701f1f6ce8e3d0fe\n"
