And the big part of the patch. Only changes were two conceptual chunks
were committed earlier, one member function name change and removal of
unnecessary vertical whitespace in a class definition.
Committing to the trunk. Posting for archival purposes.

GCC Maintainers:
The following is an updated patch to add support for the
vec_first_match_index, vec_first_match_or_eos_index,
vec_first_mismatch_index, and vec_first_mismatch_or_eos_index builtins
for ISA 3.0. I have addressed the comments from Segher and Jakub.
The patch has been re-tested on:

This patch pulls out the EVRP class & methods from tree-vrp.c. It's a
straight copy-n-paste with the exception of the evrp_folder class which
I trimmed back down to its minimal form.
This obviously forces shared structures/routines between tree-vrp.c and
tree-evrp.c to get exposed in a header fil

This patch removes unused RTL functions, introduces alternate ones for
use in a later SFN patch, and regroups other related functions so that
they appear in a more consistent order.

This patch introduces a number of new macros and functions that will
be used to distinguish between different kinds of debug stmts, insns
and notes, namely, preexisting debug bind ones and to-be-introduced
nonbind markers.
In a seemingly mechanical way, it adjusts several uses of the macros
and fu
If find_bb_boundaries is given a block with zero or one nondebug insn
beside debug insns, it shouldn't purge dead edges, because without
debug insns we wouldn't purge them at that point. Doing so may change
the order in which edges are processed, and ultimately lead to
different transformations to
This patch adjusts numerous parts of the compiler that would

Tested manually on Linux-X64, finishing testing with the full suite on

I spent far too much time contemplating whether to add a compatibility switch
for this, but -fcheck-new *is* such a compatibility switch.
OK for trunk?

Hi,
this patch completes the removal of frequencies by dropping them from
callgraph edges. The callgraph node and edge counts are now just copies
of BB counts (node count is ENTRY_BLOCK_PTR count and edge count is the count
of corresponding stmt). These counts can be local and any IPA comparsions
