c++: Function found via ADL when it should not [PR95074]
I noticed that we don't implement [basic.lookup.argdep]/3: quite correctly;
it says "If X (the lookup set produced by unqualified lookup) contains
-- a block-scope function declaration that is not a using-declaration
[...]
then Y (the lookup set produced by ADL) is empty."
but we were still performing ADL in fn1 in the attached test. The
problem was that we were only looking at the first function in the
overload set which in this case happened to be a using-declaration, and
those don't suppress ADL. We have to look through the whole set to find
out if unqualified lookup found a block-scope function declaration, or
a member function declaration.

Fix throw specifiers on interface.
I discovered that libitm:
(a) declares __cxa_allocate_exception and friends directly,
(b) doesn't mark them as 'throw()'
(c) doesn't mark the replacment fns _ITM_$foo as nothrow either
We happen to get away with it because of code in the compiler that,
although it checks the parameter types, doesn't check the exception
specification. (One reason being they used to not be part of the
language's type system, but now they are.) I suspect this can lead us
to generate pessimal code later, if we've seen one of these decls
earlier. Anyway, with modules it becomes trickier[*], so I'm trying
to clean it up and not be a problem. I see Jakub fixed part of the
problem
(https://gcc.gnu.org/pipermail/gcc-patches/2018-December/513302.html)
AFAICT, he did fix libitm's decls, but left the lax parm-type checking
in the compiler.
libitm.h is not very informative about specification:
in version 1 of http://www.intel.com/some/path/here.pdf. */
Anyway, it was too fiddly to have libitm pick up the declarations from
libsupc++. Besides it makes them weak declarations, and then provides
definitions for non-elf systems. So this patch adds the expected
'throw()'

tree-optimization/94988 - enhance SM some more
This enhances store-order preserving store motion to handle the case
of non-invariant dependent stores in the sequence of unconditionally
executed stores on exit by re-issueing them as part of the sequence
of stores on the exit. This fixes the observed regression of
gcc.target/i386/pr64110.c which relies on store-motion of 'b'
for a loop like
for (int i = 0; i < j; ++i)
*b++ = x;
where for correctness we now no longer apply store-motion. With
the patch we emit the correct
tem = b;
for (int i = 0; i < j; ++i)
{
tem = tem + 1;
*tem = x;
}
b = tem;
*tem = x;
preserving the original order of stores. A testcase reflecting
the miscompilation done by earlier GCC is added as well.
This also fixes the reported ICE in PR95025 and adds checking code
to catch it earlier - the issue was not-supported refs propagation
leaving stray refs in the sequence.

[PATCH] aarch64: prefer using csinv, csneg in zero extend contexts
Given the C code:
unsigned long long inv(unsigned a, unsigned b, unsigned c)
{
return a ? b : ~c;
}
Prior to this patch, AArch64 GCC at -O2 generates:
inv:
cmp w0, 0
mvn w2, w2
csel w0, w1, w2, ne
ret
and after applying the patch, we get:
inv:
cmp w0, 0
csinv w0, w1, w2, ne
ret
The new pattern also catches the optimization for the symmetric case where the
body of foo reads a ? ~b : c.
Similarly, with the following code:
unsigned long long neg(unsigned a, unsigned b, unsigned c)
{
return a ? b : -c;
}
GCC at -O2 previously gave:
neg:
cmp w0, 0
neg w2, w2
csel w0, w1, w2, ne
but now gives:
neg:
cmp w0, 0
csneg w0, w1, w2, ne
