FWIW, here's my (failed) stab at taking Alex' getcontext.S and the old x86_64 makecontext.c and signalcontext.c from before the removal:


It does not compile, because there is no PIC_PROLOGUE and PIC_EPILOGUE for x86_64 – I don't know why (not needed?) and my last and only steps with assembler were a long long time ago and involved only a quarter of bits so I really don't know where to go from that. But maybe the {make,signal}context implementations are of any use?
