The __cpu_indicator_init and __cpu_model symbols are not safe to use
from shared libgcc_s.so from ifunc resolvers, so since gcc-6, only
the definitions from static libgcc.a are used, however the symbols
are kept in libgcc_s as well for backward compatibility (with
appropriate symbol version).  On targets without such backward
compatibility concern add cpuinfo to the static library only (this
avoids running the ctor, reduces libgcc_s size and elf abi concerns
about the versioned symbols).

When combine splits a three-insn combination into two instructions it
can reuse i2dest for the temporary result of the first new instruction.
However all information it has in reg_stat about that register will be
stale.  This results in the simplify_gen_binary calls in change_zero_ext
using out-of-date information, which makes it think one of the ANDs
generated there always results in 0, and it doesn't get better from there.

This can also happen if a splitter in the MD uses nonzero_bits (for
example).  I tried to make the splitting code in combine save and restore
the i2dest reg_stat info, but that causes one of the acats tests to fail.

This whole reg_stat thing needs an overhaul, and/or we shouldn't reuse
i2dest for unrelated purposes when splitting.

This patch changes change_zero_ext to do the expected simplifications
itself and not call simplify_gen_*.


	PR rtl-optimization/78232

Disable unnecessary calls to dwarf2out_decl for the parents of nested
functions. This fixes a libstdc++ build regression on
x86_64-apple-darwin, as these calls used to add duplicate attributes
(for instance DW_AT_inline and DW_AT_object_pointer) to the
corresponding DW_TAG_subprogram DIE.

Bootstrapped and regtested on x86_64-linux.

match.pd transforms (A&C)|(B&~C) to ((A^B)&C)^B, which is fewer
operations if C is not const (and it is not on simple tests at least,
this transform is done very early already).

Various processors have "insert" instructions that can do this, but
combine cannot build those from the xor-and-xor, especially it has no
chance at all to do that if A or B or multiple instructions as well
(on PowerPC, the rl[wd]imi instructions can do this with together with
a rotate, or a simple shift with appropriate C; other ISAs have similar
insns).

This patch makes RTL simplify transform (xor (and (xor A B) C) B) back
to (ior (and A C) (and B ~C)) for constant C (and similar with A instead
of B for that last term).


	* simplify-rtx.c (simplify_binary_operation_1): Simplify
	(xor (and (xor A B) C) B) to (ior (and A C) (and B ~C)) and
	(xor (and (xor A B) C) A) to (ior (and A ~C) (and B C)) if C
	is a const_int.
