2011-07-07dwarf2out: Emit NOTE_INSN_CFI_* both with and without cfi-asm.Bernd Schmidt5-229/+241
This patch is essentially Bernd's 006-cfilabel patch, updated for all the other changes to dwarf2out. The patch reduces the difference between the cfi-asm and non-cfi-asm code paths. We now emit the CFI notes in all cases. Later, after we're done producing the CFI insns we need, another pass over the rtl adds the necessary labels and set_loc/advance_loc CFIs. One consequence of this is that def_cfa_1 can no longer use lookup_cfa, so it just compares to an old_cfa variable instead. The major change since Bernd's patch is that all the target-specific changes are no longer necessary. * dwarf2cfi.c (add_cfi): Remove. (dwarf2out_cfi_label): Remove force argument. Only generate the label name. (add_fde_cfi): Simplify the different code paths. (add_cie_cfi): New. (old_cfa, old_cfa_remember): New. (def_cfa_1, reg_save): Remove label, add for_cie parameter.

2011-07-07dwarf2out: Move insn scanning out of final.c.Bernd Schmidt7-55/+143
This patch is essentially Bernd's 005-scanfirst patch, updated for the introduction of the dwarf2cfi.c file. We introduce NOTE_INSN_CFI and NOTE_INSN_CFI_LABEL to hold the dwarf2 info during the bulk of final. The actual construction of these notes still happens during final, right at the very beginning of the pass, via the dwarf2out_frame_debug_init hook. * dwarf2cfi.c (cfi_insn): New. (dwarf2out_cfi_label): Don't emit cfi label here. (add_fde_cfi): Create a NOTE_INSN_CFI. (dwarf2out_frame_debug): Setup cfi_insn. (dwarf2out_frame_debug_init): Loop over insns creating CFI notes.
