Actually we should just drop the libgo/go/exp directory.  I don't know why it's
still there.  It should have been dropped years ago.

Confirmed with the following small test case.

-S -Warray-bounds -fdump-tree-wrestrict d.c

void f (void *d, unsigned n)
{
  if (n < 1) n = 1;

  __builtin_memcpy (d, a + sizeof a - n, n);
}
d.c: In function ‘void f(void*, unsigned int)’:
d.c:7:20: warning: ‘void* __builtin_memcpy(void*, const void*, unsigned int)’
offset [5, 3] is out of the bounds [0, 4] of object ‘a’ with type ‘char [4]’
[-Warray-bounds]

d.c:1:6: note: ‘a’ declared here

The range for the offset is the anti-range [4, 4] that the logic doesn't handle
correctly.

implies the failures were introduced

I can't reproduce the two failures with an x86_64-linux to
hppa-unknown-linux-gnu cross-compiler.  I can't actually run the test under
DejaGnu in my setup but when I compile it using the cross-GCC (unless I'm
overlooking something subtle) the output for the function looks the same as
with the native GCC.  I'm guessing the problem is in the interaction with the
host system but I don't have access to it to debug it.

[Bug middle-end/78918] missing -Wrestrict on memcpy copying over self

[msebor at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78918

--- Comment #8 from Martin Sebor  ---
It's an unintended effect of warning during folding.  The folder sees the
arguments propagated before the if conditional has been evaluated and before
the call has been eliminated as unreachable.  The only way of avoiding this
false positive that I can think of is to defer the folding but that's not a
popular alternative.  I've opened bug 83456 to deal with it.  Please add your
further comments there.

[Bug tree-optimization/83456] New: -Wrestrict false positive on a non-overlapping memcpy in an inline function

[msebor at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83456

Bug ID: 83456
   Summary: -Wrestrict false positive on a non-overlapping memcpy
in an inline function
   Product: gcc
   Version: 8.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: tree-optimization
  Assignee: unassigned at gcc dot gnu.org
  Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

As reported in bug 78918, comment #7, the enhanced -Wrestrict warning issues a
false positive on the following code.  The false positive is caused by issuing
the warning during folding, after bar() has been inlined but before the call to
memcpy has been eliminated.  The reason for issuing the warning in this case
(i.e., equal operands) is to help detect bugs in code built without
optimization when an unguarded overlapping call to the library function would
be made, but it may not be worth the bug reports for the safe cases like this
one.

$ cat z.c && gcc -O2 -S -Wall z.c
extern void* memcpy (void*, const void*, __SIZE_TYPE__);

inline void bar (void *d, void *s, unsigned N)
{
  if (s != d)
memcpy (d, s, N);
}

void foo (void* src)
{
  bar (src, src, 1);
}
z.c: In function ‘foo’:
z.c:6:5: warning: ‘memcpy’ source argument is the same as destination
[-Wrestrict]
 memcpy (d, s, N);

 #ifdef _GLIBCXX_USE_SENDFILE
-  off_t offset = 0;
-  const auto n = ::sendfile(out.fd, in.fd, , from_st->st_size);
-  if (n < 0 && (errno == ENOSYS || errno == EINVAL))

This change will trigger PR 70975. Older (?) Solaris 12 targets require

[Bug go/83308] Missing platform definitions for SH in libgo

[glaubitz at physik dot fu-berlin.de]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83308

--- Comment #16 from John Paul Adrian Glaubitz  ---
As for ioctl():

Linux: http://man7.org/linux/man-pages/man2/ioctl.2.html
FreeBSD: https://www.freebsd.org/cgi/man.cgi?query=ioctl=2
Plan9:
https://github.com/brho/plan9/blob/master/sys/src/ape/lib/bsd/ioctl.c#L26
Darwin:
https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man2/ioctl.2.html

So, I really think ioctl() should be declared in libgo/go/exp/terminal/util.go
accordingly:

//extern ioctl
func ioctl(int, uint, unsafe.Pointer) int

Shall I send a separate patch?

[Bug c++/83447] New: parameter after function parameter pack gets improperly deduced

Status: UNCONFIRMED
  Severity: normal
  Priority: P3

This example compiles:

template 
void foo(Args..., T ) { }

int main() {
foo(0);
}

with Args deducing as empty and T as int. But Args is a non-deduced context
(http://eel.is/c++draft/temp#deduct.type-5.7). And I don't think "trailing" can
be said to apply to Args here
(http://eel.is/c++draft/temp#arg.explicit-3.sentence-2). The call should fail.

I guess I can add a case matching for sh(2|3)*-*-* and one for sh4*-*-* then.

I think J-Core planned to stay with the 16-bit encoding. I tested it with
PC_QUANTUM=2 and it works on my SH-4A machine.

Ok.

Great, thank you!
