This should be largely fixed now, the missing piece that might be important in
some cases is CSE of permutes (or two-operator nodes) and of extern CTORs.

[Bug target/115554] New: RISC-V: ICE in case of multiple target-arch attributes

[cmuellner at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115554

Bug ID: 115554
   Summary: RISC-V: ICE in case of multiple target-arch attributes
   Product: gcc
   Version: 15.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: target
  Assignee: unassigned at gcc dot gnu.org
  Reporter: cmuellner at gcc dot gnu.org
  Target Milestone: ---

Minimal reproducers (for target-arch):

extern
__attribute__((target("arch=+zba")))
__attribute__((target("arch=+zbb")))
void foo(void);

extern
__attribute__((target("arch=+zbb")))
__attribute__((target("arch=+zbb")))
void bar(void);

The ICE is a bug.
If multiple target-arch attributes should not be allowed,
then an error message is the right solution.

Allowing multiple target-X attributes is problematic, as can be seen for baz().
I.e., does the second attribute amend or replace the previous one?
However, accepting multiple target-X attributes if they are equal (like for
bar)
could be done.

The assertion was added in the GCC 14 cycle (commit 9941f0295a1).
GCC 14 and 15 are affected. GCC 13 is not affected (we don't have RISC-V
target-arch
attributes in GCC 13).

The ICE looks like this:

[Bug middle-end/115551] [missed optimization] "c1 << (a + c2)" not optimized into "(c1 << c2) << a"

[burnus at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115551

--- Comment #3 from Tobias Burnus  ---
As we want to have a >= 0, I tried to convey it differently for the example in
comment 0:

(a) __attribute__((assume(ch >= 0)));
(b) 'unsigned ch' (instead of 'int ch')

but it didn't help.  Thus, it looks as if it could be implemented for:
  c1 << (a + c2)
if (a >= 0 and c2 >= 0) doing then the conversion
  (c1 << c2) << a

Whether Ranger handles abs(c2) > c3 >= 0 → a >= 0 for 'c1 << (a*c2 + c3)', I
don't know, but the variant above with unsigned and 'assume(a >= 0)' should be
implementable and seems to make sense.

Forgot to mention:
The ICE is triggered by an assertion in riscv_func_target_put(), which ensures
we don't have more than one target-arch attribute in one function declaration.

Yes, this was simply bad timing. The patch hit the GCC 12.4 freeze. I already

the patch makes sense on GCC 11.

all same for right-shifts (both logical and arithmetic).

Note that 1 << (a + 5) might be cheaper than (1<<5) << a due to constraints
on immediates but for GIMPLE the latter is definitely more canonical.

Stumbled over this when looking at PR 115551.

C has for the bitwise shift operators:

"If the value of the right operand is negative or is greater than or equal to
the
width of the promoted left operand, the behavior is undefined."

Thus, it seems as if the ranger should be able to deduce 'a >= 0' in the
following, such that both conditions can be optimized away:

int f (int a, float *b) {
   *b = a >= 0 ? 1.0 : 2.0;
   int mask1 = 1U << a;  // 'a' must be >= 0 → '*b=1.0' above and 'return -1'
below
   if (a >= 0)
 return -1;
   return mask1;
}

We should also verify that it doesn't stand in the way of shift sanitization,
because
unsigned int a;
...
1 << (5 + a);
is well defined only for a in [0, 26] while once we optimize it to
(1 << 5) << a;
that would be well defined for a in [0, 31].  I think the shift sanitization is
done early, so just something to be verified in a testcase next to the patch.

bitint: Fix up lowering of COMPLEX_EXPR [PR115544]

We don't really support _Complex _BitInt(N), the only place we use
bitint complex types is for the .{ADD,SUB,MUL}_OVERFLOW internal function
results and COMPLEX_EXPR in the usual case should be either not present
yet because the ifns weren't folded and will be lowered, or optimized
into something simpler, because normally the complex bitint should be
used just for extracting the 2 subparts from it.
Still, with disabled optimizations it can occassionally happen that it
appears in the IL and that is why there is support for lowering those,
but it doesn't handle optimizing those too much, so if it uses SSA_NAME,
it relies on them having a backing VAR_DECL during the lowering.
This is normally achieves through the
  && ((is_gimple_assign (use_stmt)
   && (gimple_assign_rhs_code (use_stmt)
   != COMPLEX_EXPR))
  || gimple_code (use_stmt) == GIMPLE_COND)
hunk in gimple_lower_bitint, but as the following testcase shows, there
is one thing I've missed, the load optimization isn't guarded by the
above stuff.  So, either we'd need to add support for loads to
lower_complexexpr_stmt, or because they should be really rare, this
patch just disables the load optimization if at least one load use is
a COMPLEX_EXPR (like we do already for PHIs, calls, asm).

and so add_misspelling_candidates works correctly for it, but 3 out of
these,
{ "--machine", "", "-m", false, false },
{ "--machine", "no-", "-m", false, true },
and
{ "--std", "", "-std=", false, false },
use non-NULL opt1.  That says that
--machine foo
should map to
-mfoo
and
--machine no-foo
should map to
-mno-foo
and
--std c++17
should map to
-std=c++17
add_misspelling_canidates was not handling this, so it hapilly
registered say
--stdc++17
or
--machineavx512
(twice) as spelling alternatives, when those options aren't recognized.
Instead we support
--std c++17
or
--machine avx512
--machine no-avx512

The following patch fixes that.  On this particular testcase, we no longer
suggest anything, even when among the suggestion is say that
--std c++17
or
-std=c++17
etc.

c-family: Fix -Warray-compare warning ICE [PR115290]

The warning code uses %D to print the ARRAY_REF first operands.
That works in the most common case where those operands are decls, but
as can be seen on the following testcase, they can be other expressions
with array type.
Just changing %D to %E isn't enough, because then the diagnostics can
suggest something like
note: use '&(x) != 0 ? (int (*)[32])&a : (int (*)[32])&b[0] == &(y) != 0 ?
(int (*)[32])&a : (int (*)[32])&b[0]' to compare the addresses
which is a bad suggestion, the %E printing doesn't know that the
warning code will want to add & before it and [0] after it.
So, the following patch adds ()s around the operand as well, but does
that only for non-decls, for decls keeps it as &arr[0] like before.

2024-06-17  Jakub Jelinek  

PR c/115290
* c-warn.cc (do_warn_array_compare): Use %E rather than %D for
printing op0 and op1; if those operands aren't decls, also print
parens around them.

* c-c++-common/Warray-compare-3.c: New test.
