Add functionality that indicates which insns are added by -minit-regs, such
that for instance we have for pr53465.s:
...
// #APP
// 9 "gcc/testsuite/gcc.c-torture/execute/pr53465.c" 1
// Start: Added by -minit-regs=3:
// #NO_APP
mov.u32 %r26, 0;
// #APP
// 9 "gcc/testsuite/gcc.c-torture/execute/pr53465.c" 1
// End: Added by -minit-regs=3:
// #NO_APP
...
Can be switched off using -mno-ptx-comment.
Tested on nvptx.

With nvptx target, driver version 510.47.03 and board GT 1030 I, we run into:
...
FAIL: gcc.c-torture/execute/pr53465.c -O1 execution test
FAIL: gcc.c-torture/execute/pr53465.c -O2 execution test
FAIL: gcc.c-torture/execute/pr53465.c -O3 -g execution test
...
while the test-cases pass with nvptx-none-run -O0.
The problem is that the generated ptx contains a read from an uninitialized
ptx register, and the driver JIT doesn't handle this well.
For -O2 and -O3, we can get rid of the FAIL using --param
logical-op-non-short-circuit=0. But not for -O1.
At -O1, the test-case minimizes to:
...
void __attribute__((noinline, noclone))
foo (int y) {
int c;
for (int i = 0; i < y; i++)
{
int d = i + 1;
if (i && d <= c)
__builtin_abort ();
c = d;
}
}
int main () {
foo (2); return 0;
}
...
Note that the test-case does not contain an uninitialized use. In the first
iteration, i is 0 and consequently c is not read. In the second iteration, c
is read, but by that time it's already initialized by 'c = d' from the first
iteration.
AFAICT the problem is introduced as follows: the conditional use of c in the
loop body is translated into an unconditional use of c in the loop header:
...
# c_1 = PHI <c_4(D)(2), c_9(6)>
...
which forwprop1 propagates the 'c_9 = d_7' assignment into:
...
# c_1 = PHI <c_4(D)(2), d_7(6)>
...
which ends up being translated by expand into an unconditional:
...
(insn 13 12 0 (set (reg/v:SI 22 [ c ])
(reg/v:SI 23 [ d ])) -1
(nil))
...
at the start of the loop body, creating an uninitialized read of d on the
path from loop entry.
By disabling coalesce_ssa_name, we get the more usual copies on the incoming
edges. The copy on the loop entry path still does an uninitialized read, but
that one's now initialized by init-regs. The test-case passes, also when
disabling init-regs, so it's possible that the JIT driver doesn't object to
this type of uninitialized read.
Now that we characterized the problem to some degree, we need to fix this,
because either:
- we're violating an undocumented ptx invariant, and this is a compiler bug,
or
- this is is a driver JIT bug and we need to work around it.
There are essentially two strategies to address this:
- stop the compiler from creating uninitialized reads
- patch up uninitialized reads using additional initialization
The former will probably involve:
- making some optimizations more conservative in the presence of
uninitialized reads, and
- disabling some other optimizations (where making them more conservative is
not possible, or cannot easily be achieved).
This will probably will have a cost penalty for code that does not suffer from
the original problem.
The latter has the problem that it may paper over uninitialized reads
in the source code, or indeed over ones that were incorrectly introduced
by the compiler. But it has the advantage that it allows for the problem to
be addressed at a single location.
There's an existing pass, init-regs, which implements a form of the latter,
but it doesn't work for this example because it only inserts additional
initialization for uses that have not a single reaching definition.
Fix this by adding initialization of uninitialized ptx regs in reorg.
Control the new functionality using -minit-regs=<0|1|2|3>, meaning:
- 0: disabled.
- 1: add initialization of all regs at the entry bb
- 2: add initialization of uninitialized regs at the entry bb
- 3: add initialization of uninitialized regs close to the use
and defaulting to 3.

In nvptx_reorg_uniform_simt we have a loop:
...
for (insn = get_insns (); insn; insn = next)
{
next = NEXT_INSN (insn);
if (!(CALL_P (insn) && nvptx_call_insn_is_syscall_p (insn))
&& !(NONJUMP_INSN_P (insn)
&& GET_CODE (PATTERN (insn)) == PARALLEL
&& get_attr_atomic (insn)))
continue;
...
that intends to handle syscalls and atomic insns.
However, this also silently skips the atomic insn nvptx_atomic_store, which
has GET_CODE (PATTERN (insn)) == SET.
This does not cause problems, because the nvptx_atomic_store actually maps
onto a "st" insn, and therefore is not atomic and doesn't need to be handled
by nvptx_reorg_uniform_simt.
Fix this by:
- explicitly setting nvptx_atomic_store's atomic attribute to false,
- rewriting the skip condition to make sure all insn
with atomic attribute are handled, and
- asserting that all handled insns are PARALLEL.

With the default ptx isa 6.0, we have for uniform-simt-1.c:
...
@%r33 atom.global.cas.b32 %r26, [a], %r28, %r29;
shfl.sync.idx.b32 %r26, %r26, %r32, 31, 0xffffffff;
...
The atomic insn is predicated by -muniform-simt, and the subsequent insn does
a warp sync, at which point the warp is uniform again.
But with -mptx=3.1, we have instead:
...
@%r33 atom.global.cas.b32 %r26, [a], %r28, %r29;
shfl.idx.b32 %r26, %r26, %r32, 31;
...
The shfl does not sync the warp, and we want the warp to go back to executing
uniformly asap. We cannot enforce this, but at least check this using
nvptx_uniform_warp_check, similar to how that is done for openacc.
Likewise, detect the case that no shfl insn is emitted, and add a
nvptx_uniform_warp_check or nvptx_warpsync.

The ptx isa specifies (for pre-sm_7x) that atomic operations on shared memory
locations do not guarantee atomicity with respect to normal store instructions
to the same address.
This can be fixed by:
- inserting barriers between normal stores and atomic operations to a common
address
- using atom.exch to store to locations accessed by other atomic operations.
It's not clearly spelled out which barriers are needed, and a barrier seem more
expensive than atomic exchange.
Implement the pre-sm_7x shared atomic store using atomic exchange.
That includes stores using generic addressing, since those may also point to
shared memory.

There's a nvidia driver JIT bug that mishandles this code (minimized from
builtin-arith-overflow-15.c):
...
int main (void) {
signed char r;
unsigned char y = (unsigned char) 0x80;
if (__builtin_sub_overflow ((unsigned char)0, (unsigned char)y, &r))
__builtin_abort ();
return 0;
}
...
which at ptx level minimizes to:
...
mov.u16 r22, 0x0080;
st.local.u16 [frame_var],r22;
ld.local.u16 r32,[frame_var];
sub.u16 r33,0x0000,r32;
cvt.u32.u16 r35,r33;
...
where we expect r35 == 0x0000ff80 but get instead 0xffffff80, and where using
nvptx-none-run -O0 fixes the problem. [ See also

Many thanks to Thomas Schwinge for confirming my hypothesis that the register
usage regression, PR target/104345, is solely due to libgcc's _muldc3 function.
In addition to the isinf functionality in the previously proposed nvptx patch at
https://gcc.gnu.org/pipermail/gcc-patches/2022-January/588453.html which
significantly reduces the number of instructions in _muldc3, the patch below
further reduces both the number of instructions and the number of explicitly
declared registers, by permitting floating point constant immediate operands
in nvptx's copysign instruction.
Fingers-crossed, the combination with all of the previous proposed nvptx
patches improves things. Ultimately, increasing register usage from 50 to
51 registers, reducing the number of concurrent threads by ~2%, can easily
be countered if we're now executing significantly fewer instructions in each
kernel, for a net performance win.
This patch has been tested on nvptx-none hosted on x86_64-pc-linux-gnu
with a "make" and "make -k check" with no new failures.

This patch addresses the "increased register pressure" regression on
nvptx-none caused by my change to transition the backend to a
STORE_FLAG_VALUE = 1 target. This improved code generation for the
more common case of producing 0/1 Boolean values, but unfortunately
made things marginally worse when a 0/-1 mask value is desired.
Unfortunately, nvptx kernels are extremely sensitive to changes in
register usage, which was observable in the reported PR.
This patch provides optimizations for -(cond ? 1 : 0), effectively
simplify this into cond ? -1 : 0, where these ternary operators are
provided by nvptx's selp instruction, and for the specific case of
SImode, using (restoring) nvptx's "set" instruction (which avoids
the need for a predicate register).
This patch has been tested on nvptx-none hosted on x86_64-pc-linux-gnu
with a "make" and "make -k check" with no new failures. Unfortunately,
the exact register usage of a nvptx kernel depends upon the version of
the Cuda drivers being used (and the hardware), but I believe this
change should resolve the PR (for Thomas) by improving code generation
for the cases that regressed.

This patch adds support for nvptx's BImode and.pred, or.pred and
xor.pred instructions. Technically, nvptx.md previously defined
andbi3, iorbi3 and xorbi3 instructions, but the assembly language
mnemonic output for these was incorrect (e.g. and.b1) and would be
rejected by the ptxas assembler. The most significant part of this
patch is the new define_split which teaches the compiler to actually
use these instructions when appropriate (exposing the latent bug above).
After https://gcc.gnu.org/pipermail/gcc-patches/2022-January/587999.html,
the function:
int foo(int x, int y) { return (x==21) && (y==69); }
when compiled with -O2 produces:
mov.u32 %r26, %ar0;
mov.u32 %r27, %ar1;
setp.eq.u32 %r31, %r26, 21;
setp.eq.u32 %r34, %r27, 69;

selp.u32 %r38, 1, 0, %r34;
and.b32 %value, %r37, %r38;
with this patch we now save an extra instruction and generate:

Now that the middle-end MULT_HIGHPART_EXPR pieces are in place, this
patch adds support for nvptx's mul.hi.s64 and mul.hi.u64 instructions,
as previously reviewed (provisionally pre-approved) back in August 2020:
https://gcc.gnu.org/pipermail/gcc-patches/2020-August/551373.html
Since then a few things have changed, so this patch uses the new
SMUL_HIGHPART and UMUL_HIGHPART RTX expressions, but the test cases
remain the same. Like the x86_64 backend, this patch retains the
"trunc" forms of these instructions (while the RTL optimizers/combine
may still generate them).
Given that we're rapidly approaching stage 4, I also took the liberty
of including support in nvptx.md for a few other instructions. With
the new 64-bit highpart multiplication instructions added above, we
can now provide a define_expand for efficient 64-bit (to 128-bit)
widening multiplications. This patch also adds support for nvptx's
testp.infinite instruction (for implementing __builtin_isinf) and
the not.pred instruction.
As an example of the code generation improvements, the function
int foo(double x) { return __builtin_isinf(x); }
previously generated with -O2:
mov.f64 %r26, %ar0;
abs.f64 %r28, %r26;
setp.leu.f64 %r31, %r28, 0d7fefffffffffffff;
selp.u32 %r30, 1, 0, %r31;

One of the unusual target features of the Nvidia PTX ISA is that it
doesn't provide QI mode (byte sized) operations or registers. Somewhat
conventionally, 8-bit quantities are read from/written to memory using
special instructions, but stored internally using SImode (32-bit) registers.
GCC's middle-end accomodates targets without QImode optabs, by widening
operations until suitable support is found, and with the current nvptx
backend this means 16-bit HImode operations. The inconvenience is that
nvptx is also a TARGET_TRULY_NOOP_TRUNCATION=false target, meaning that
additional instructions are required to convert between the SImode
registers used to hold QImode values, and the HImode registers used to
operate on them (and back again). This results in a large amount of
shuffling and type conversion in code dealing with bytes, i.e. using
char or Boolean types.
This patch improves the situation by providing expanders in the nvptx
machine description to perform QImode operations natively in SImode
instead of HImode. An alternate implementation might be to provide
some form of target hook to specify which fallback modes to use during
RTL expansion, but I think this requirement is unusual, and a solution
entirely in the nvptx backend doesn't disturb/affect other targets.
The improvements can be quite dramatic, as shown in the example below:
int foo(int x, int y) { return (x==21) && (y==69); }
previously with -O2 required 15 instructions:
mov.u32 %r26, %ar0;
mov.u32 %r27, %ar1;
setp.eq.u32 %r31, %r26, 21;
selp.u32 %r30, 1, 0, %r31;
mov.u32 %r29, %r30;
setp.eq.u32 %r34, %r27, 69;
selp.u32 %r33, 1, 0, %r34;
mov.u32 %r32, %r33;

and.b16 %r35, %r36, %r37;
cvt.u32.u16 %r38, %r35;
cvt.u32.u8 %value, %r38;
with this patch, now requires only 7 instructions:
mov.u32 %r26, %ar0;
mov.u32 %r27, %ar1;
setp.eq.u32 %r31, %r26, 21;
setp.eq.u32 %r34, %r27, 69;

This patch adds more support for _Float16 (HFmode) to the nvptx backend.
Currently negation, absolute value and floating point comparisons are
implemented by promoting to float (SFmode). This patch adds suitable
define_insns to nvptx.md, most conditional on TARGET_SM53 (-misa=sm_53).
This patch also adds support for HFmode fused multiply-add.
One subtlety is that neghf2 and abshf2 are implemented by (HImode)
bit manipulation operations to update the sign bit. The NVidia PTX
ISA documentation for neg.f16 and abs.f16 contains the caution
"Future implementations may comply with the IEEE 754 standard by preserving
the (NaN) payload and modifying only the sign bit". Given the availability
of suitable replacements, I thought it best to provide IEEE 754 compliant
implementations. If anyone observes a performance penalty from this
choice I'm happy to provide a -ffast-math variant (or revisit this
decision).
This patch has been tested on nvptx-none hosted on x86_64-pc-linux-gnu
(including newlib) with a make and make -k check with no new failures.

While testing with driver version 390.147 I ran into the problem that it
doesn't support ptx isa version 6.3 (the new default), only 6.1.
Furthermore, using the -mptx option is a bit user-unfriendly.
Say we want to compile for sm_80. We can use -misa=sm_80 to specify that, but
then run into errors because the default ptx version is 6.3, which doesn't
support sm_80 yet.
Address both these issues by:
- picking a default -mptx based on the active -misa, and
- ensuring that the default -mptx is at least 6.0 (instead
of 6.3).
Also add an error in case of incompatible options like
"-misa=sm_80 -mptx=6.3":
...
cc1: error: PTX version (-mptx) needs to be at least 7.0 to support \
selected -misa (sm_80)

In PR target/104364, two problems were reported:
- in muniform-simt mode, an atom.cas insn is no longer executed in the
"master lane" only.
- in msoft-stack mode, an __atomic_compare_exchange_n on stack memory is
translated assuming it accesses local memory, while that's not the case.
Fix these by:
- ensuring that all insns with atomic attribute are also predicable, such
that the validate_change in nvptx_reorg_uniform_simt will succeed, and
asserting that it does, and
- guarding the local atomics implementation with a new function
nvptx_mem_local_p that correctly handles msoft-stack.

On a GT 1030, with driver version 470.94 and -mptx=3.1 I run into:

which minimizes to the same test-case as listed in commit "[nvptx]
Update default ptx isa to 6.3".
The problem is again that the first diverging branch is not handled as such in
SASS, which causes problems with a subsequent shfl insn, but given that we
have -mptx=3.1 we can't use the bar.warp.sync insn.
Given that the default is now -mptx=6.3, and consequently -mptx=3.1 is of a
lesser importance, implement the next best thing: abort when detecting
non-convergence using this insn:
...
{ .reg.b32 act;
vote.ballot.b32 act,1;
.reg.pred uni;
setp.eq.b32 uni,act,0xffffffff;
@ !uni trap;
@ !uni exit;
}
...
Interestingly, the effect of this is that rather than aborting, the test-case
now passes.

$L15:

and when inspecting the generated SASS, the branch is not setup as a divergent
branch, but instead as a regular branch.
This causes us to execute a shfl.sync insn in divergent mode, which is likely
to cause trouble given a remark in the ptx isa version 6.3, which mentions
that for .target sm_6x or below, all threads must excute the same
shfl.sync instruction in convergence.
Fix this by placing a "bar.warp.sync 0xffffffff" at the desired convergence
point (in the example above, after $L15).

The FAIL does not happen with GOMP_NVPTX_JIT=-O0.
The problem seems to be that the shfl insns for the vector reduction are not
executed uniformly by the warp. Enforcing this by using shfl.sync fixes the
problem.
Fix this by setting the ptx isa to 6.3 by default, which allows the use of
shfl.sync.

In ptx isa 6.0, a new barrier instruction was added, and bar.sync was
redefined as barrier.sync.aligned.
The aligned modifier indicates that all threads in a CTA will execute the same
barrier instruction.
The seems fine for a form "bar.sync 0".
But a "bar.sync %rx,64" (as used for vector length > 32) may execute a
diffferent barrier depending on the value of %rx, so we can't assume it's
aligned.
Fix this by using "barrier.sync %rx,64" instead.

The ptx insn atom doesn't support local memory. In case of doing an atomic
operation on local memory, we run into:
...
operation not supported on global/shared address space
...
This is the cuGetErrorString message for CUDA_ERROR_INVALID_ADDRESS_SPACE.
The message is somewhat confusing given that actually the operation is not
supported on local address space.
Fix this by falling back on a non-atomic version when detecting
a frame-related memory operand.
This only solves some cases that are detected at compile-time. It does
however fix the openacc private-atomic-* test-cases.

This is a simple patch, now that the nvptx backend has transitioned
to STORE_FLAG_VALUE=1, that adds support for NVidia's cnot instruction,
that implements C/C++ style logical negation.
Previously, the simple function:
int foo(int x) { return !x; }
on nvptx-none with -O2 would generate:
mov.u32 %r24, %ar0;
setp.eq.u32 %r28, %r24, 0;
selp.u32 %value, 1, 0, %r28;
with this patch, GCC now generates:
mov.u32 %r24, %ar0;
cnot.b32 %value, %r24;

This patch to the nvptx backend changes the backend's STORE_FLAG_VALUE
from -1 to 1, by using BImode predicates and selp instructions, instead
of set instructions (almost always followed by integer negation).
Historically, it was reasonable (through rare) for backends to use -1
for representing true during the RTL passes. However with tree-ssa,
GCC now emits lots of code that reads and writes _Bool values, requiring
STORE_FLAG_VALUE=-1 targets to frequently convert 0/-1 pseudos to 0/1
pseudos using integer negation. Unfortunately, this process prevents
or complicates many optimizations (negate isn't associative with logical
AND, OR and XOR, and interferes with range/vrp/nonzerobits bounds etc.).
The impact of this is that for a relatively simple logical expression
like "return (x==21) && (y==69);", the nvptx backend currently generates:
mov.u32 %r26, %ar0;
mov.u32 %r27, %ar1;
set.u32.eq.u32 %r30, %r26, 21;
neg.s32 %r31, %r30;
mov.u32 %r29, %r31;
set.u32.eq.u32 %r33, %r27, 69;
neg.s32 %r34, %r33;
mov.u32 %r32, %r34;
cvt.u16.u8 %r39, %r29;
mov.u16 %r36, %r39;
cvt.u16.u8 %r39, %r32;
mov.u16 %r37, %r39;
and.b16 %r35, %r36, %r37;
cvt.u32.u16 %r38, %r35;
cvt.u32.u8 %value, %r38;
This patch tweaks nvptx to generate 0/1 values instead, requiring the
same number of instructions, using (BImode) predicate registers and selp
instructions so as to now generate the almost identical:
mov.u32 %r26, %ar0;
mov.u32 %r27, %ar1;
setp.eq.u32 %r31, %r26, 21;
selp.u32 %r30, 1, 0, %r31;
mov.u32 %r29, %r30;
setp.eq.u32 %r34, %r27, 69;
selp.u32 %r33, 1, 0, %r34;
mov.u32 %r32, %r33;
cvt.u16.u8 %r39, %r29;
mov.u16 %r36, %r39;
cvt.u16.u8 %r39, %r32;
mov.u16 %r37, %r39;
and.b16 %r35, %r36, %r37;
cvt.u32.u16 %r38, %r35;
cvt.u32.u8 %value, %r38;
The hidden benefit is that this sequence can (in theory) be optimized
by the RTL passes to eventually generate a much shorter sequence using
an and.pred instruction (just like Nvidia's nvcc compiler).
This patch has been tested nvptx-none with a "make" and "make -k check"
(including newlib) hosted on x86_64-pc-linux-gnu with no new failures.

This patch introduces some new define_insn rules to the nvptx backend,
to perform sign-extension of a truncation (from and to the same mode),
using a single cvt instruction. As an example, the following function
int foo(int x) { return (char)x; }
with -O2 currently generates:
mov.u32 %r24, %ar0;
mov.u32 %r26, %r24;
cvt.s32.s8 %value, %r26;
and with this patch, now generates:
mov.u32 %r24, %ar0;
cvt.s32.s8 %value, %r24;
This patch has been tested on nvptx-none hosted by x86_64-pc-linux-gnu
with a top-level "make" (including newlib) and a "make check" with no
new regressions.
gcc/ChangeLog:
* config/nvptx/nvptx.md (*extend_trunc_<mode>2_qi,

This patch adds a __PTX_SM__ predefined macro to the nvptx backend that
allows code to check the compute model being targeted by the compiler.
This is equivalent to the __CUDA_ARCH__ macro defined by CUDA's nvcc
compiler, but to avoid causing problems for source code that checks
for that compiler, this macro uses GCC's nomenclature; it's easy
enough for users to "#define __CUDA_ARCH__ __PTX_SM__".
What might have been a four line patch is actually a little more
complicated, as this patch takes the opportunity to upgrade the
nvptx backend to use the now preferred nvptx-c.c idiom.

[PR90115]
This patch implements a method to track the "private-ness" of
OpenACC variables declared in offload regions in gang-partitioned,
worker-partitioned or vector-partitioned modes. Variables declared
implicitly in scoped blocks and those declared "private" on enclosing
directives (e.g. "acc parallel") are both handled. Variables that are
e.g. gang-private can then be adjusted so they reside in GPU shared
memory.
The reason for doing this is twofold: correct implementation of OpenACC
semantics, and optimisation, since shared memory might be faster than
the main memory on a GPU. Handling of private variables is intimately
tied to the execution model for gangs/workers/vectors implemented by
a particular target: for current targets, we use (or on mainline, will
soon use) a broadcasting/neutering scheme.
That is sufficient for code that e.g. sets a variable in worker-single
mode and expects to use the value in worker-partitioned mode. The
difficulty (semantics-wise) comes when the user wants to do something like
an atomic operation in worker-partitioned mode and expects a worker-single
(gang private) variable to be shared across each partitioned worker.
Forcing use of shared memory for such variables makes that work properly.
In terms of implementation, the parallelism level of a given loop is
not fixed until the oaccdevlow pass in the offload compiler, so the
patch delays fixing the parallelism level of variables declared on or
within such loops until the same point. This is done by adding a new
internal UNIQUE function (OACC_PRIVATE) that lists (the address of) each
private variable as an argument, and other arguments set so as to be able
to determine the correct parallelism level to use for the listed
variables. This new internal function fits into the existing scheme for
demarcating OpenACC loops, as described in comments in the patch.
Two new target hooks are introduced: TARGET_GOACC_ADJUST_PRIVATE_DECL and
TARGET_GOACC_EXPAND_VAR_DECL. The first can tweak a variable declaration
at oaccdevlow time, and the second at expand time. The first or both
of these target hooks can be used by a given offload target, depending
on its strategy for implementing private variables.
This patch updates the TARGET_GOACC_ADJUST_PRIVATE_DECL target hook in
the AMD GCN backend to the current name and prototype. (An earlier
version of the hook was already present, but dormant.)

The atomic ops in nvptx.md have memmodel arguments, which are currently
ignored.
Handle these, fixing test-case fails libgomp.c-c++-common/reduction-{5,6}.c
on volta.

Add nvptx option -mptx that sets the ptx ISA version. This is currently
hardcoded to 3.1.

The r12-220-gd96db15967e78d7cecea3b1cf3169ceb924678ac change
deprecated some non-standard std::pair constructors and that apparently
broke nvptx.c build, where pseudo_node_t is std::pair<struct basic_block_def *, int>
and so nullptr (or NULL) needs to be used for the first argument of the
ctors instead of 0.
