The problem is after r14-2587-gd8105b10fff951, the definition of
extended_count now takes a bool as its last argument but we only
have a declaration for the version which takes an int as the last
argument. This fixes the problem by changing the declaration to be
a bool too.
Committed as obvious after building a cross to alpha-linux-gnu.
gcc/ChangeLog:
PR target/110778
* rtl.h (extended_count): Change last argument type
to bool.

Since we have statistics_counter_event now, combine should use that
instead of it is own custom printing of statistics.
The only thing that is not done any more after this patch is printing
out the total stats for the whole TU.
Note you need to use -fdump-rtl-combine-stats to get the stats in the combine
dump unlike before where the stats was dumped directly into the file.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
* combine.cc (dump_combine_stats): Remove.

We are running out of the machine_mode(8 bits) in RISC-V backend. Thus
we would like to extend the machine_mode bit size from 8 to 16 bits.
However, it is sensitive to extend the memory size in common structure
like tree or rtx. This patch would like to extend the machine_mode bits
to 16 bits by shrinking, like:
* Swap the bit size of code and machine code in rtx_def.
* Adjust the machine_mode location and spare in tree.
The memory impact of this patch for correlated structure looks like below:
+-------------------+----------+---------+------+
| struct/bytes | upstream | patched | diff |
+-------------------+----------+---------+------+
| rtx_obj_reference | 8 | 12 | +4 |
| ext_modified | 2 | 4 | +2 |
| ira_allocno | 192 | 184 | -8 |
| qty_table_elem | 40 | 40 | 0 |
| reg_stat_type | 64 | 64 | 0 |
| rtx_def | 40 | 40 | 0 |
| table_elt | 80 | 80 | 0 |
| tree_decl_common | 112 | 112 | 0 |
| tree_type_common | 128 | 128 | 0 |
| access_info | 8 | 8 | 0 |
+-------------------+----------+---------+------+
The tree and rtx related struct has no memory changes after this patch,
and the machine_mode changes to 16 bits already.

Many functions defined in our headers are declared 'static inline' which
is a C idiom whose use predates our move to C++ as the implementation
language. But in C++ the inline keyword is more than just a compiler
hint, and is sufficient to give the function the intended semantics.
In fact declaring a function both static and inline is a pessimization
since static effectively disables the desired definition merging
behavior enabled by inline, and is also a source of (harmless) ODR
violations when a static inline function gets called from a non-static
inline one (such as tree_operand_check calling tree_operand_length).
This patch mechanically fixes the vast majority of occurrences of this
anti-pattern throughout the compiler's headers via the command line
sed -i 's/^static inline/inline/g' gcc/*.h gcc/*/*.h
There's also a manual change to remove the redundant declarations
of is_ivar and lookup_category in gcc/objc/objc-act.cc which would
otherwise conflict with their modified definitions in objc-act.h
(due to the difference in staticness).
Besides fixing some ODR violations, this speeds up stage1 cc1plus by
about 2% and reduces the size of its text segment by 1.5MB.

This is the first in a series of patches to enable discriminator support
in AutoFDO.
This patch switches to tracking discriminators per statement/instruction
instead of per basic block. Tracking per basic block was problematic since
not all statements in a basic block needed a discriminator and, also, later
optimizations could move statements between basic blocks making correlation
during AutoFDO compilation unreliable. Tracking per statement also allows
us to assign different discriminators to multiple function calls in the same
basic block. A subsequent patch will add that support.
The idea of this patch is based on commit 4c311d95cf6d9519c3c20f641cc77af7df491fdf
by Dehao Chen in vendors/google/heads/gcc-4_8 but uses a slightly different
approach. In Dehao's work special (normally unused) location ids and side tables
were used to keep track of locations with discriminators. Things have changed
since then and I don't think we have unused location ids anymore. Instead,
I made discriminators a part of ad-hoc locations.
The difference from Dehao's work also includes support for discriminator
reading/writing in lto streaming and in modules.
Tested on x86_64-pc-linux-gnu.

* basic-block.h: Remove discriminator from basic blocks.

Currently we only ever call emit_conditional_move with the comparison
(as well as its comparands) we got from the jump. Thus, backends are
going to emit a CC comparison for every conditional move that is being
generated instead of re-using the existing CC.
This, combined with emitting temporaries for each conditional move,
causes sky-high costs for conditional moves.
This patch allows to re-use a CC so the costing situation is improved a
bit.

[PR102356]
Seems simplify_associate_operation is quadratic, which isn't a big deal
for use during combine and other similar RTL passes, because those never
try to combine expressions from more than a few instructions and because
those instructions need to be recognized the machine description also bounds
how many expressions can appear in there.
var-tracking has depth limits only for some cases and unlimited depth
for the vt_expand_loc though:
/* This is the value used during expansion of locations. We want it
to be unbounded, so that variables expanded deep in a recursion
nest are fully evaluated, so that their values are cached
correctly. We avoid recursion cycles through other means, and we
don't unshare RTL, so excess complexity is not a problem. */
#define EXPR_DEPTH (INT_MAX)
/* We use this to keep too-complex expressions from being emitted as
location notes, and then to debug information. Users can trade
compile time for ridiculously complex expressions, although they're
seldom useful, and they may often have to be discarded as not
representable anyway. */
#define EXPR_USE_DEPTH (param_max_vartrack_expr_depth)
IMO for very large expressions it isn't worth trying to reassociate though,
in fact e.g. for the new testcase below keeping it as is has bigger chance
of generating smaller debug info which the dwarf2out.c part of the change
tries to achieve - if a binary operation has the same operands, we can
use DW_OP_dup and not bother computing the possibly large operand again.
The patch fixes it by adding a counter to simplify_context and counting
how many times simplify_associative_operation has been called during
a single outermost simplify_* call, and once it reaches some maximum
(currently 64), it stops reassociating.
Another possibility to deal with the power expressions in debug info
would be to introduce some new RTL operation for the pow{,i} (x, n)
case, allow that solely in debug insns and expand those into DWARF
using a loop. But that seems like quite a lot of work for something rarely
used (especially when powi for larger n is only useful for 0 and 1 inputs
because anything else overflows).

This patch gets CSE to re-use constants already inside a vector rather than
re-materializing the constant again.
Basically consider the following case:
#include <stdint.h>
#include <arm_neon.h>
uint64_t
test (uint64_t a, uint64x2_t b, uint64x2_t* rt)
{
uint64_t arr[2] = { 0x0942430810234076UL, 0x0942430810234076UL};
uint64_t res = a | arr[0];
uint64x2_t val = vld1q_u64 (arr);
*rt = vaddq_u64 (val, b);
return res;
}
The actual behavior is inconsequential however notice that the same constants
are used in the vector (arr and later val) and in the calculation of res.
The code we generate for this however is quite sub-optimal:
test:
adrp x2, .LC0
sub sp, sp, #16
ldr q1, [x2, #:lo12:.LC0]
mov x2, 16502
movk x2, 0x1023, lsl 16
movk x2, 0x4308, lsl 32
add v1.2d, v1.2d, v0.2d
movk x2, 0x942, lsl 48
orr x0, x0, x2
str q1, [x1]
add sp, sp, 16
ret
.LC0:
.xword 667169396713799798
.xword 667169396713799798
Essentially we materialize the same constant twice. The reason for this is
because the front-end lowers the constant extracted from arr[0] quite early on.
If you look into the result of fre you'll find
<bb 2> :
arr[0] = 667169396713799798;
arr[1] = 667169396713799798;
res_7 = a_6(D) | 667169396713799798;
_16 = __builtin_aarch64_ld1v2di (&arr);
_17 = VIEW_CONVERT_EXPR<uint64x2_t>(_16);
_11 = b_10(D) + _17;
*rt_12(D) = _11;
arr ={v} {CLOBBER};
return res_7;
Which makes sense for further optimization. However come expand time if the
constant isn't representable in the target arch it will be assigned to a
register again.
(insn 8 5 9 2 (set (reg:V2DI 99)
(const_vector:V2DI [
(const_int 667169396713799798 [0x942430810234076]) repeated x2
])) "cse.c":7:12 -1
(nil))
...
(insn 14 13 15 2 (set (reg:DI 103)
(const_int 667169396713799798 [0x942430810234076])) "cse.c":8:12 -1
(nil))
(insn 15 14 16 2 (set (reg:DI 102 [ res ])
(ior:DI (reg/v:DI 96 [ a ])
(reg:DI 103))) "cse.c":8:12 -1
(nil))
And since it's out of the immediate range of the scalar instruction used
combine won't be able to do anything here.
This will then trigger the re-materialization of the constant twice.
To fix this this patch extends CSE to be able to generate an extract for a
constant from another vector, or to make a vector for a constant by duplicating
another constant.
Whether this transformation is done or not depends entirely on the costing for
the target for the different constants and operations.
I Initially also investigated doing this in PRE, but PRE requires at least 2 BB
to work and does not currently have any way to remove redundancies within a
single BB and it did not look easy to support.

Add a new RTL simplification for the case of a VEC_SELECT selecting
the low part of a vector. The simplification returns a SUBREG.
The primary goal of this patch is to enable better combinations of
Neon RTL patterns - specifically allowing generation of 'write-to-
high-half' narrowing intructions.
Adding this RTL simplification means that the expected results for a
number of tests need to be updated:
* aarch64 Neon: Update the scan-assembler regex for intrinsics tests
to expect a scalar register instead of lane 0 of a vector.
* aarch64 SVE: Likewise.
* arm MVE: Use lane 1 instead of lane 0 for lane-extraction
intrinsics tests (as the move instructions get optimized away for
lane 0.)
This patch also adds new code generation tests to
narrow_high_combine.c to verify the benefit of this RTL
simplification.

This removes CC0 and all directly related infrastructure.
CC_STATUS, CC_STATUS_MDEP, CC_STATUS_MDEP_INIT, and NOTICE_UPDATE_CC
are deleted and poisoned. CC0 is only deleted (some targets use that
name for something else). HAVE_cc0 is automatically generated, and we
no longer will do that after this patch.
CC_STATUS_INIT is suggested in final.c to also be useful for ports that
are not CC0, and at least arm seems to use it for something. So I am
leaving that alone, but most targets that have it could remove it.

PR99929 is one of those “how did we get away with this for so long”
bugs: the equality routines weren't checking whether two variable-length
CONST_VECTORs had the same encoding. This meant that:
{ 1, 0, 0, 0, 0, 0, ... }
would appear to be equal to:
{ 1, 0, 1, 0, 1, 0, ... }
since both are represented using the elements { 1, 0 }.

One of the recurring warts of RTL is that multiplication by a power
of 2 is represented as a MULT inside a MEM but as an ASHIFT outside
a MEM. It would obviously be better if we didn't have this kind of
context sensitivity, but it would be difficult to remove.
Currently the simplify-rtx.c routines are hard-coded for the
ASHIFT form. This means that some callers have to convert the
ASHIFTs “back” into MULTs after calling the simplify-rtx.c
routines; see fwprop.c:canonicalize_address for an example.
I think we can relieve some of the pain by wrapping the simplify-rtx.c
routines in a simple class that tracks whether the expression occurs
in a MEM or not, so that no post-processing is needed.
An obvious concern is whether passing the “this” pointer around
will slow things down or bloat the code. I can't measure any
increase in compile time after applying the patch. Sizewise,
simplify-rtx.o text increases by 2.3% in default-checking builds
and 4.1% in release-checking builds.
I realise the MULT/ASHIFT thing isn't the most palatable
reason for doing this, but I think it might be useful for
other things in future, such as using local nonzero_bits
hooks/virtual functions instead of the global hooks.
The obvious alternative would be to add a static variable
and hope that it is always updated correctly.
Later patches make use of this.

As discussed in the PR, if !ACCUMULATE_OUTGOING_ARGS on large functions we
can have hundreds of thousands of stack pointer adjustments and cselib
creates a new VALUE after each sp adjustment, which form extremely deep
VALUE chains, which is very harmful e.g. for find_base_term.
E.g. if we have
sp -= 4
sp -= 4
sp += 4
sp += 4
sp -= 4
sp += 4
that means 7 VALUEs, one for the sp at beginning (val1), than val2 = val1 -
4, then val3 = val2 - 4, then val4 = val3 + 4, then val5 = val4 + 4, then
val6 = val5 - 4, then val7 = val6 + 4.
This patch tweaks cselib, so that it is smarter about sp adjustments.
When cselib_lookup (stack_pointer_rtx, Pmode, 1, VOIDmode) and we know
nothing about sp yet (this happens at the start of the function, for
non-var-tracking also after cselib_reset_table and for var-tracking after
processing fp_setter insn where we forget about former sp values because
that is now hfp related while everything after it is sp related), we
look it up normally, but in addition to what we have been doing before
we mark the VALUE as SP_DERIVED_VALUE_P. Further lookups of sp + offset
are then special cased, so that it is canonicalized to that
SP_DERIVED_VALUE_P VALUE + CONST_INT (if possible). So, for the above,
we get val1 with SP_DERIVED_VALUE_P set, then val2 = val1 - 4, val3 = val1 -
8 (note, no longer val2 - 4!), then we get val2 again, val1 again, val2
again, val1 again.
In the find_base_term visited_vals.length () > 100 find_base_term
statistics during combined x86_64-linux and i686-linux bootstrap+regtest
cycle, without the patch I see:
find_base_term > 100
returning NULL returning non-NULL
32-bit compilations 4229178 407
64-bit compilations 217523 0
with largest visited_vals.length () when returning non-NULL being 206.
With the patch the same numbers are:
32-bit compilations 1249588 135
64-bit compilations 3510 0
with largest visited_vals.length () when returning non-NULL being 173.
This shows significant reduction of the deep VALUE chains.
On powerpc64{,le}-linux, these stats didn't change at all, we have
1008 0
for all of -m32, -m64 and little-endian -m64, just the
gcc.dg/pr85180.c and gcc.dg/pr87985.c testcases which are unrelated to sp.
My earlier version of the patch, which contained just the rtl.h and cselib.c
changes, regressed some tests:
gcc.dg/guality/{pr36728-{1,3},pr68860-{1,2}}.c
gcc.target/i386/{pr88416,sse-{13,23,24,25,26}}.c
The problem with the former tests was worse debug info, where with -m32
where arg7 was passed in a stack slot we though a push later on might have
invalidated it, when it couldn't. This is something I've solved with the
var-tracking.c (vt_initialize) changes. In those problematic functions, we
create a cfa_base VALUE (argp) and want to record that at the start of
the function the argp VALUE is sp + off and also record that current sp
VALUE is argp's VALUE - off. The second permanent equivalence didn't make
it after the patch though, because cselib_add_permanent_equiv will
cselib_lookup the value of the expression it wants to add as the equivalence
and if it is the same VALUE as we are calling it on, it doesn't do anything;
and due to the cselib changes for sp based accesses that is exactly what
happened. By reversing the order of the cselib_add_permanent_equiv calls we
get both equivalences though and thus are able to canonicalize the sp based
accesses in var-tracking to the cfa_base value + offset.
The i386 FAILs were all ICEs, where we had pushf instruction pushing flags
and then pop pseudo reading that value again. With the cselib changes,
cselib during RTL DSE is able to see through the sp adjustment and wanted
to replace_read what was done pushf, by moving the flags register into a
pseudo and replace the memory read in the pop with that pseudo. That is
wrong for two reasons: one is that the backend doesn't have an instruction
to move the flags hard register into some other register, but replace_read
has been validating just the mem -> pseudo replacement and not the insns
emitted by copy_to_mode_reg. And the second issue is that it is obviously
wrong to replace a stack pop which contains stack post-increment by a copy
of pseudo into destination. dse.c has some code to handle RTX_AUTOINC, but
only uses it when actually removing stores and only when there is REG_INC
note (stack RTX_AUTOINC does not have those), in check_for_inc_dec* where
it emits the reg adjustment(s) before the insn that is going to be deleted.
replace_read doesn't remove the insn, so if it e.g. contained REG_INC note,
it would be kept there and we might have the RTX_AUTOINC not just in *loc,
but other spots.
So, the dse.c changes try to validate the added insns and punt on all
RTX_AUTOINC in *loc. Furthermore, it seems that with the cselib.c changes
on the gfortran.dg/pr87360.f90 and gcc.target/i386/pr88416.c testcases
check_for_inc_dec{,_1} happily throws stack pointer autoinc on the floor,
which is also wrong. While we could perhaps do the for_each_inc_dec
call regardless of whether we have REG_INC note or not, we aren't prepared
to handle e.g. REG_ARGS_SIZE distribution and thus could end up with wrong
unwind info or ICEs during dwarf2cfi.c. So the patch also punts on those,
after all, if we'd in theory managed to try to optimize such pushes before,
we'd create wrong-code.
On x86_64-linux and i686-linux, the patch has some minor debug info coverage
differences, but it doesn't appear very significant to me.

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.

choose_hard_reg_mode previously took a boolean saying whether the
mode needed to be call-preserved. This patch replaces it with an
optional ABI pointer instead, so that the function can use that
to test whether a value is call-saved.
default_dwarf_frame_reg_mode uses eh_edge_abi because that's the
ABI that matters for unwinding. Targets need to override the hook
if they want something different.

This patch replaces get_call_reg_set_usage with insn_callee_abi,
which returns the ABI of the target of a call insn. The ABI's
full_reg_clobbers corresponds to regs_invalidated_by_call,
whereas many callers instead passed call_used_or_fixed_regs, i.e.:
(regs_invalidated_by_call | fixed_reg_set)
The patch slavishly preserves the "| fixed_reg_set" for these callers;
later patches will clean this up.

When one passes short-lived fake rtxes to backends in order to test
their capabilities, it might be beneficial to allocate these rtxes on
stack in order to reduce the load on GC.
