This change fixes a bug in the AArch64 backend. Currently, we accept an
odd sign_extract representation of addresses, but don't accept that same
odd form of address as an LEA.
This is the cause of PR96998. In the testcase given in the PR, combine
produces:
(insn 9 8 10 3 (set (mem:SI (plus:DI (sign_extract:DI (mult:DI (subreg:DI (reg/v:SI 92 [ g ]) 0)
(const_int 4 [0x4]))
(const_int 34 [0x22])
(const_int 0 [0]))
(reg/f:DI 96)) [3 *i_5+0 S4 A32])
(asm_operands:SI ("") ("=Q") 0 []
[]
[] test.c:11)) "test.c":11:5 -1
(expr_list:REG_DEAD (reg/v:SI 92 [ g ])
(nil)))
Then LRA reloads the address and we ICE because we fail to recognize the
sign_extract outside the mem:
(insn 33 8 34 3 (set (reg:DI 100)
(sign_extract:DI (ashift:DI (subreg:DI (reg/v:SI 92 [ g ]) 0)
(const_int 2 [0x2]))
(const_int 34 [0x22])
(const_int 0 [0]))) "test.c":11:5 -1
(nil))
The aarch64 changes here remove the support for this sign_extract
representation of addresses, fixing PR96998. Now this by itself would
regress code quality, so this change is paired with an improvement to
combine which prevents an extract rtx from being emitted in this case:
we now write the rtx above as a shift of an extend, which allows the
combination to go ahead.
Prior to this, combine.c:make_extraction() identified where we can emit
an ashift of an extend in place of an extraction, but failed to make the
corresponding canonicalization/simplification when presented with a mult
by a power of two. Such a representation is canonical when representing
a left-shifted address inside a mem.
This change remedies this situation. For rtxes such as:
(mult:DI (subreg:DI (reg:SI r) 0) (const_int 2^n))
where the bottom 32 + n bits are valid (the higher-order bits are
undefined) and make_extraction() is being asked to sign_extract the
lower (valid) bits, after the patch, we rewrite this as:
(mult:DI (sign_extend:DI (reg:SI r)) (const_int 2^n))
instead of using a sign_extract.

The following testcases are miscompiled (the first one since my improvements
to rotate discovery on GIMPLE, the other one for many years) because
combiner optimizes nested ROTATEs with narrowing SUBREG in between (i.e.
the outer rotate is performed in shorter precision than the inner one) to
just one ROTATE of the rotated constant. While that (under certain
conditions) can work for shifts, it can't work for rotates where we can only
do that with rotates of the same precision.

Since we now only call is_just_move on the original instructions, we
always have an rtx_insn* (not just a pattern), so we can use single_set
on it. This makes no detectable difference at all on all thirty Linux
targets I test, but it does help cris, and it is simpler, cleaner code
anyway.

side-effects [PR94873]
There were some discussions about whether REG_EQUAL notes are valid on insns with a single
set which contains auto-inc-dec side-effects in the SET_SRC and the majority thinks that
it should be valid. So, this patch fixes the combiner to punt in that case, because otherwise
the auto-inc-dec side-effects from the SET_SRC are lost.

The following testcase ICEs on armv7hl-linux-gnueabi.
try_combine is called on:
(gdb) p debug_rtx (i3)
(insn 20 12 22 2 (set (mem/c:SI (plus:SI (reg/f:SI 102 sfp)
(const_int -4 [0xfffffffffffffffc])) [1 x+0 S4 A32])

]) "pr94291.c":7:8 248 {*movsi_compare0}

and tries to recognize cc = r121 cmp 0; [sfp-4] = r121 parallel,
but that isn't recognized, so it splits it into two: split_i2i3
[sfp-4] = r121 followed by cc = r121 cmp 0 which is recognized, but
ICEs because the code below insist that the SET_DEST of newi2pat
(or first set in PARALLEL thereof) must be a REG or SUBREG of REG,
but it is a MEM in this case. I don't see any condition that would
guarantee that, perhaps for the swap_i2i3 case it was somehow guaranteed.
As the code just wants to update LOG_LINKS and LOG_LINKS are only for
registers, not for MEM or anything else, the patch just doesn't update those
if it isn't a REG or SUBREG of REG.

[PR93908]
git is miscompiled on s390x-linux with -O2 -march=zEC12 -mtune=z13.
I've managed to reduce it into the following testcase. The problem is that
during combine we see the s->k = -1; bitfield store and change the SET_SRC
from a pseudo into a constant:
(set (zero_extract:DI (mem/j:HI (plus:DI (reg/v/f:DI 60 [ s ])
(const_int 10 [0xa])) [0 +0 S2 A16])
(const_int 2 [0x2])
(const_int 7 [0x7]))
(const_int -1 [0xffffffffffffffff]))
This on s390x with the above option isn't recognized as valid instruction,
so find_split_point decides to handle it as IOR or IOR/AND.
src is -1, mask is 3 and pos is 7.
src != mask (this is also incorrect, we want to set all (both) bits in the
bitfield), so we go for IOR/AND, but instead of trying
mem = (mem & ~0x180) | ((-1 << 7) & 0x180)
we actually try
mem = (mem & ~0x180) | (-1 << 7)
and that is further simplified into:
mem = mem | (-1 << 7)
aka
mem = mem | 0xff80
which doesn't set just the 2-bit bitfield, but also many other bitfields
that shouldn't be touched.
We really should do:
mem = mem | 0x180
instead.
The problem is that we assume that no bits but those low len (2 here) will
be set in the SET_SRC, but there is nothing that can prevent that, we just
should ignore the other bits.
The following patch fixes it by masking src with mask, this way already
the src == mask test will DTRT, and as the code for or_mask uses
gen_int_mode, if the most significant bit is set after shifting it left by
pos, it will be properly sign-extended.

What happens on this testcase is with the out of bounds rotate we get:
Trying 13 -> 16:
13: r129:SI=r132:DI#0<-<0x20
REG_DEAD r132:DI
16: r123:DI=r129:SI<0
REG_DEAD r129:SI
Successfully matched this instruction:
(set (reg/v:DI 123 [ <retval> ])
(const_int 0 [0]))
during combine. So, perhaps we could also change simplify-rtx.c to punt
if it is out of bounds rather than trying to optimize anything.
Or, but probably GCC11 material, if we decide that ROTATE/ROTATERT doesn't
have out of bounds counts or introduce targetm.rotate_truncation_mask,
we should truncate the argument instead of punting.
Punting is better for backports though.

This addresses PR 91860 which has four testcases triggering internal errors.
The problem here is that in combine when handling debug insns, we are trying
to substitute
(sign_extend:DI (const_int 8160 [0x1fe0]))
as the value for
(reg:DI 78 [ _9 ])
in the debug insn
(debug_insn 29 28 30 2 (var_location:QI d (subreg:QI (reg:DI 78 [ _9 ]) 0)) "tmp4.c":11:5 -1
(nil))
This eventually triggers an abort because 8160 is not a sign-extended
QImode value.
In subst there is already code check for a CONST_INT inside a ZERO_EXTEND and
simplify it. This needs to be extended to also handle a SIGN_EXTEND the same
way.

The AArch64 SVE tlsdesc patterns were the main motivating reason
for clobber_high. It's no longer needed now that the patterns use
calls instead.
At the time, one of the possible future uses for clobber_high was for
asm statements. However, the current code wouldn't handle that case
without modification, so I think we might as well remove it for now.
We can always reapply it in future if it turns out to be useful again.

There shouldn't be many cases in which a useful hard register is
live across a call before RA, so we might as well keep things simple
and invalidate partially-clobbered registers here, in case the values
they hold leak into the call-clobbered part. In principle this is
a bug fix for TARGET_HARD_REGNO_CALL_PART_CLOBBERED targets,
but in practice it probably doesn't make a difference.

I have a series of patches that (as a side effect) makes all rtl
passes use the information collected by -fipa-ra. This showed up a
latent bug in the liveness tracking in regrename.c, which doesn't take
CALL_INSN_FUNCTION_USAGE into account when processing clobbers.
This actually seems to be quite a common problem with passes that use
note_stores; only a handful remember to walk CALL_INSN_FUNCTION_USAGE
too. I think it was just luck that I saw it with regrename first.
This patch tries to make things more robust by passing an insn rather
than a pattern to note_stores. The old function is still available
as note_pattern_stores for the few places that need it.
When updating callers, I've erred on the side of using note_stores
rather than note_pattern_stores, because IMO note_stores should be
the default choice and we should only use note_pattern_stores if
there's a specific reason. Specifically:
* For cselib.c, "body" may be a COND_EXEC_CODE instead of the main
insn pattern.
* For ira.c, I wasn't sure whether extending no_equiv to
CALL_INSN_FUNCTION_USAGE really made sense, since we don't do that
for normal call-clobbered registers. Same for mark_not_eliminable
in reload1.c
* Some other places only have a pattern available, and since those
places wouldn't benefit from walking CALL_INSN_FUNCTION_USAGE,
it seemed better to alter the code as little as possible.
* In the config/ changes, quite a few callers have already weeded
out CALL insns. It still seemed better to use note_stores rather
than prematurely optimise. (note_stores should tail call to
note_pattern_stores once it sees that the insn isn't a call.)
The patch also documents what SETs mean in CALL_INSN_FUNCTION_USAGE.

Two fixes for UB when handling very large offsets. The calculation in
force_int_to_mode would have been correct if signed integers used modulo
arithmetic, so just switch to unsigned types. The calculation in
rtx_addr_can_trap_p_1 didn't handle overflow properly, so switch to
known_subrange_p instead (which is supposed to handle all cases).

The code that checks if an auto-increment from i0 or i1 is not lost is
a bit shaky. The code to check the same for i2 is non-existent, and
cannot be implemented in a similar way at all. So, this patch counts
all auto-increments, and makes sure we end up with the same number as
we started with. This works because we still have a check that we
will not duplicate any.
We should do this some better way, but not while we are in stage 4.

PR target/88861 reports an ICE in "ce2" due to an unreachable
basic block.
The block becomes unreachable in "combine" when delete_noop_moves
deletes an insn with a REG_EH_REGION, deleting the EH edge, the
only edge leading to the basic block.
Normally, rest_of_handle_combine would call cleanup_cfg, deleting
unreachable blocks, if combine_instructions returns true, and
combine_instructions does return true for some cases of edge-removal,
but it doesn't for this case, leading to the ICE.
This patch updates delete_noop_moves so that it returns true if
it deletes any edges, and passes that through to combine_instructions,
so that it too will return true if any edges were deleted, ensuring that
cleanup_cfg will be called by rest_of_handle_combine for this case,
deleting the now-unreachable block, and fixing the ICE.

This makes make_more_copies do what its documentation says, that is,
only make an intermediate pseudo if copying to a pseudo.
This regressed generated code quality when we didn't keep the original
notes that were on the copy, but since r265582 we do, and only allowing
pseudos now is a win. It also simplifies the code.

The code with an intermediate register is perfectly fine, but LRA

This rewrites most of make_more_copies, in the process fixing a few PRs

On most targets every function starts with moves from the parameter
passing (hard) registers into pseudos. Similarly, after every call
there is a move from the return register into a pseudo. These moves
usually combine with later instructions (leaving pretty much the same
instruction, just with a hard reg instead of a pseudo).
This isn't a good idea. Register allocation can get rid of unnecessary
moves just fine, and moving the parameter passing registers into many
later instructions tends to prevent good register allocation. This
patch disallows combining moves from a hard (non-fixed) register.
This also avoid the problem mentioned in PR87600 #c3 (combining hard
registers into inline assembler is problematic).
Because the register move can often be combined with other instructions
*itself*, for example for setting some condition code, this patch adds
extra copies via new pseudos after every copy-from-hard-reg.
On some targets this reduces average code size. On others it increases
it a bit, 0.1% or 0.2% or so. (I tested this on all *-linux targets).

This patch allows combine to combine two insns into two. This helps
in many cases, by reducing instruction path length, and also allowing
further combinations to happen. PR85160 is a typical example of code
that it can improve.
This patch does not allow such combinations if either of the original
instructions was a simple move instruction. In those cases combining
the two instructions increases register pressure without improving the
code. With this move test register pressure does no longer increase
noticably as far as I can tell.
(At first I also didn't allow either of the resulting insns to be a
move instruction. But that is actually a very good thing to have, as
should have been obvious).

The current code in reg_nonzero_bits_for_combine allows using the
reg_stat info when last_set_mode is a different integer mode. This is
completely wrong for non-pseudos. For example, as in the PR, a value
in a DImode hard register is set by eight writes to its constituent
QImode parts. The value written to the DImode is not the same as that
written to the lowest-numbered QImode!
