[Bug c++/86384] New: Scoped enumeration instantiated even if not required
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86384
Bug ID: 86384
Summary: Scoped enumeration instantiated even if not required
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
The code is as follow:
template
struct A {
enum class B {
X = T::value
};
};
int main() {
A a;
}
g++ error:
code0.c.cpp:4:13: error: 'value' is not a member of 'int'
enum class B {
^
This code looks well-formed. Only if we look into the enumeration, as
"A::B::X", the definition of the enumeration is required to exist and thus
implicitly instantiated. This is specified at 14.7.1p1 and p2. I tried clang++.
It accepts the code without any error message.
[Bug target/86383] arm-netbsdelf cross compiler fails in selftests

We removed support for the deprecated arm6 CPU in GCC 9 but arm*-*-netbsdelf* uses it as the default if no --with-cpu is given. We should move the default CPU up to something more modern. CC'ing the NetBSD OS port maintainers. Can you recommend a more recent default arm CPU to be the default?

[Bug c/86380] New: Incorrect inequality in function chose_multiplier in file expmed.c in GCC.8.1.0 and earlier versions
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86380
Bug ID: 86380
Summary: Incorrect inequality in function chose_multiplier in
file expmed.c in GCC.8.1.0 and earlier versions
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: colinwb at yahoo dot co.uk
Target Milestone: ---
In this line near the end of function choose_multiplier in file expmed.c
return mhigh.to_uhwi () >= mask;
the ">=" should really be ">".
As it is when precision = n < HOST_BITS_PER_WIDE_INT and d = 2**(n-1) + 1,
so post_shift = 2*n - 1 - n = n - 1 and mhigh = 2**n - 1,
choose_multiplier wrongly returns that the upper bit should be set.
unsigned HOST_WIDE_INT
choose_multiplier (unsigned HOST_WIDE_INT d, int n, int precision,
unsigned HOST_WIDE_INT *multiplier_ptr,
int *post_shift_ptr, int *lgup_ptr)
...
*post_shift_ptr = post_shift;
*lgup_ptr = lgup;
if (n < HOST_BITS_PER_WIDE_INT)
{
unsigned HOST_WIDE_INT mask = (HOST_WIDE_INT_1U << n) - 1;
*multiplier_ptr = mhigh.to_uhwi () & mask;
return mhigh.to_uhwi () >= mask;
}
else
{
*multiplier_ptr = mhigh.to_uhwi ();
return wi::extract_uhwi (mhigh, HOST_BITS_PER_WIDE_INT, 1);
}
}
