Firstly, it adds back the split conditions that I accidentally removed.
Without it the dot insns are never generated, or rather, always split
back to a separate compare instruction.
Secondly, the shift amount should be SI always, not GPR, or GCC will
insert a zero-extend at expand time that it cannot get rid of later.
The test tests whether dot-form instructions are generated for both
"dot" and "dot2" cases, that is, with just a CC output or also a GPR
output; for all four basic shifts, with a register amount or an
immediate amount. It also tests for superfluous zero-extends. This
also tests if combine "simplifies" the rotates to right-rotates, which
it shouldn't do anymore.

Many targets do not have both rotate and rotatert. Of the 47 targets
in the tree, 17 have both, 9 have only rotate, 2 have only rotatert, and
19 have neither (this is based on "grep -wil" so it can be slightly off).
rs6000 has only rotate, and mips has only rotatert. For such targets
simplifying rotate to rotatert and vice versa is not simplifying things
at all. rs6000 has already way too many rotate patterns (some days it
seems like two thousand, but it is somewhat less in reality still); I
would prefer not to double that again.
So, this patch makes genrecog define HAVE_rotate and HAVE_rotatert if
those RTL codes are mentioned anywhere in the machine description, and
then does the transformation in simplify-rtx.c only if both these flags
are set.

This introduces the "bench" build target, which can be used to run

It is also possible to run subsets of benchmarks with the

When compiling a small-enough compilation unit that has no address table
entries, but complex enough that -freorder-blocks-and-partition produces
location lists, dwarf2out_finish does not call index_location_lists, but
optimize_location_lists will later assume that the addr_index_table has
been indexed.

When resolve_addr_in_expr replaces a CONST_STRING rtx, it directly
updates the pointer to the old expression with the new one. In the
case of a DW_OP_GNU_addr_index or DW_OP_GNU_const_index, that pointer
may be in an address table entry, which is keyed by the rtx. Instead
of directly replacing the pointer, we need to remove the old address
table entry (i.e., decrement its reference count), and add a new one.

When a system macro is expanded in a non-system file during
out-of-line preprocessing, it can happen that the preprocessor forgets
to emit line markers to express the system-ness status of tokens that
come after the expansion of the macro.
That can lead to situations where the entire non-system file can be
considered as being a system file and thus have its warnings be
discarded during the compilation of the resulting preprocessed file.
My understanding is that this is due to the preprocessor not
systematically detecting (and reporting) the change in system-ness of
tokens.
And this is what this patch does. Each time the system-ness of a
given token is different from the previous token that was emitted by
the preprocessor, it emits a line marker for the sole purpose of
marking the new system-ness of the subsequent tokens to come.
Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

useless adjacent line markers.
