{committed for rearnsha}
It turns out that because the compiler uses a hash table to save the
cl_target_option structures it is unsafe to modify the result of
build_target_option_node() (doing so will cause the hash lookup to
fail). This PR was due to not properly understanding this limitation.
The fix is to create temporary copies of the cl_target_option nodes for
use during target option processing and then only creating the tree node
once the options have been suitably modified.

The varargs code for SVR4 puts all (integer) arguments in 4-byte slots.
When it then reads an item from there as something not a multiple of 4
bytes, it needs to adjust the address if big endian. We didn't yet do
that.

Currently, on PowerPC, code compiled with -fstack-protector will load
the canary from -0x7010(13) (for -m64) or from -0x7008(2) (for -m32)
if GCC was compiled against GNU libc 2.4 or newer or some other libc
that supports -fstack-protector, and from the global variable
__stack_chk_guard otherwise.
This does not work well for Linux and other OS kernels and similar.
For such non-standard applications, this patch creates a few new
command-line options. The relevant new use cases are:
-mstack-protector-guard=global
Use the __stack_chk_guard variable, no matter how this GCC was
configured.
-mstack-protector-guard=tls
Use the canary from TLS. This will error out if this GCC was built
with a C library that does not support it.
-mstack-protector-guard=tls -mstack-protector-register=<reg>
-mstack-protector-offset=<offset>
Load the canary from offset <off> from base register <reg>.

This patch simplifies the handling of EH return. We force the use of the
frame pointer so the return location is always at FP + 8. This means we
can emit a simple volatile access in EH_RETURN_HANDLER_RTX without needing md
patterns, splitters and frame offset calculations. The new implementation also
fixes various bugs in aarch64_final_eh_return_addr, which does not work with
-fomit-frame-pointer, alloca or outgoing arguments.

If a jump always falls through but that cannot be optimised away, like
is the case with the PowerPC bdnz insn if its jump target is the same as
the fallthrough, sched gets confused if it schedules some instructions
from before that jump instruction to behind it: it splits the
fallthrough branch, but the jump target isn't updated, and things fall
apart as in the PR. This patch fixes it.
The second patch fragment makes -fsched-verbose=N work for N>=4; the
currently scheduled fragment can now contain a label. Everything else

A big source of cache misses when compiling a recent version of
gimple-match.ii was the call to cv_cache.empty () in clear_cv_cache.
The problem was that at one early point the hash table had grown
to 8191 entries (128k on LP64 hosts). It then stayed at that size
for the rest of the compilation, even though subsequent uses needed
only a small number of entries (usually fewer than ten). We would
still clear the whole 128k each time clear_cv_cache was called.
empty() already looks for cases where the hash table is very big
and cuts it down. At the moment it fires when the table is 1M
in size and reduces it to the next selected prime above 1K (so
almost 2K in practice). One fix would have been to lower the
threshold, but that didn't feel like the right approach. Reducing
the current limit of 1M by a factor of 8 would be pretty significant
on its own, but I think this cv_cache behaviour would have been a
problem even with 64k or 32k tables.
I think the existing check is really for cases in which even a
well-populated table would need to be shrunk rather than cleared.
Here the problem isn't that the table is excessively big in
absolute terms, more that one outlier has made the table much
too big for the general case.
traverse() already shrinks the table if it's "too empty",
which is taken to be if:
no. elements * 8 < capacity && capacity > 32
So an alternative would be to apply the same test (and the same choice
of shrunken size) to empty_slow too. The patch below does this.
It gives a 2.5% improvement in gimple-match.ii compile time at -O0 -g
and doesn't seem to adversely affect any other tests I've tried.
Of course, there's a theoretical risk of a table alternating between
one large element count and one small element count. If there was a
factor of eight difference between the two, we could shrink the table
on seeing each small element count, then grow it again when adding the
large number of elements. That seems pretty unlikely in practice
though.
Also, empty_slow() does involve a traversal if some form of manual
gc is needed on active elements, so trying to recover from an outlier
should have even more benefit there. (cv_cache uses automatic gc and so
the traversal gets optimised away.)
The calculation of the existing 1M threshold was assuming that each
entry was pointer-sized. This patch makes it use the actual size of the
entry instead.
Tested on aarch64-linux-gnu and x86_64-linux-gnu.

record_reg_classes is often the hottest function when generating
unoptimised output. It seems typical for over 60% of the instructions
it handles to be moves, and of course moves tend to be the instructions
with the longest constraint strings.
Maybe we should avoid using move constraints to set costs in unoptimised
output and instead use the "natural" class for the mode being moved.
That's too invasive for stage 3 though.
However, seeing so many moves means that we see many "failing"
alternatives, usually because of '*' or because of hard registers
in function call sequences. The frequency of alternatives that are
detected as failures after the first operand tends again to be more
than 60%. Previously we would continue to process the other operands
of the alternative regardless. This patch instead adds a short-cut.
As well as avoiding unnecessary work, it means that the alt_fail
variable can be jump-threaded away.
Tested on aach64-linux-gnu and x86_64-linux-gnu. It reduces compile
time by about 1% on some tests with "-g -O0".
