2011-07-23dwarf2cfi: Generate and connect traces.Richard Henderson3-408/+446
This kinda-sorta corresponds to Bernd's 007-dw2cfi patch. Certainly the same concepts of splitting the instruction stream into extended basic blocks is the same. This patch does a bit better job with the documentation. Also, I'm a bit more explicit about matching things up with the similar code from the regular CFG routines. What's missing at this point is any attempt to use DW_CFA_remember_state. I've deferred that for the moment because it's easy to test the state change code across epilogues, whereas the shrink-wrapping code is not in this tree and section switching is difficult to force. * dwarf2cfi.c: Include basic-block.h. (dw_label_info): Remove. (trace_work_list, trace_index): New. (remember_row, emit_cfa_remember): Remove. (dw_trace_info_hash, dw_trace_info_eq): New. (get_trace_index, get_trace_info): New.
