H A D | intr_machdep.c | diff 105733 Tue Oct 22 16:03:15 MDT 2002 jake - Expand struct trapframe to 256 bytes, make all fields fixed width and the same size. Add some fields that previously overlapped with something else or were missing. - Make struct regs and struct mcontext (minus floating point) the same as struct trapframe so converting between them is easy (null). - Add space for saving floating point state to struct mcontext. This requires that it be 64 byte aligned. - Add assertions that none of these structures change size, as they are part of the ABI. - Remove some dead code in sendsig(). - Save and restore %gsr in struct trapframe. Remember to restore %fsr. - Add some comments to exception.S. |
