flow.c (calculate_global_regs_live): Invalidate eh registers on eh edges.
2006-09-13 Andreas Krebbel <krebbel1@de.ibm.com>
* flow.c (calculate_global_regs_live): Invalidate eh registers
on eh edges. Renamed invalidated_by_call to invalidated_by_eh_edge.
(propagate_block): Handle eh registers as if they were set at basic
block start.
* except.c (dw2_build_landing_pads): Don't emit clobbers for eh
registers.
* global.c (global_conflicts): Make eh registers to conflict with
pseudos live at basic block begin.
* basic_block.h (bb_has_eh_pred): New function.
