Hi,
I'm not sure that the example below is valid but still I'd like to understand
difference in vectorizer behavior for add and sub.
Let consider two following c++ functions (https://godbolt.org/g/WxjdMP):
void testAdd(signed char a[], int N, signed int k) {
for (int i = 0; i < N; i++)
a[i] += k;
}
void testSub(signed char a[], int N, signed int k) {
for (int i = 0; i < N; i++)
a[i] -= k;
}
for testAdd vectorizer is able to utilize packed byte size paddb instruction
while for sub it is not. Instead it uses psubd resulting in a big additional
code to convert vector of i8 to vector of i32 and vice versa.
I wonder whether it is possible to utilize psubb for the second case.
I noticed that both gcc and icc is able to do that...

gdip_adjust_arrowcap_setup,
gdip_adjust_arrowcap_clone_cap,
gdip_adjust_arrowcap_destroy,
gdip_adjust_arrowcap_draw };
Formatting this code with clang-format removes the spaces inside the
initializer list:
static CapClass vtable = {CustomLineCapTypeAdjustableArrow,
gdip_adjust_arrowcap_setup,
gdip_adjust_arrowcap_clone_cap,
gdip_adjust_arrowcap_destroy,
gdip_adjust_arrowcap_draw};
Please provide a way (e.g. something like SpacesInSquareBrackets) to provide
the functionality to add spaces inside an initializer list.

https://bugs.llvm.org/show_bug.cgi?id=35299
Bug ID: 35299
Summary: Potential improvement for Loop Vectorization: XMM vs
YMM vs ZMM
Product: libraries

What is motivation to choose the lowest Vectorization Factor for equal vector
cost?
Specifically in LoopVectorizationCostModel::selectVectorizationFactor(unsigned
MaxVF):
for (unsigned i = 2; i <= MaxVF; i *= 2) {
...
if (VectorCost < Cost) {
Cost = VectorCost;
Width = i;
}
}
...
VectorizationFactor Factor = {Width, (unsigned)(Width * Cost)};
return Factor;
So we update vectorization factor to higher value only if the cost is strongly
less than previous computed cost.
So if the computed vectorization cost is equal for XMM, YMM and ZMM we always
will use XMM.
So my question is why it is done on this way?
why not to choose the maximum VF for equal cost?

Summary: Add a an option like SpaceBeforeParens but before
indexers/square brackets

E.g. The Mono coding guidelines say to put a spsce before '[' in an indexer
int main() {
static int x[] = {1, 2, 3};
return x [0];
}
The code above gets formatted to:
int main() {
static int x[] = {1, 2, 3};
return x[0];
}
Notice that the space is missing in `x [0]`
Ideally this would not apply to declarations, but I guess this could be
controlled with an enum option

[llvm-bugs] [Bug 35302] New: missing namespaces when underlying type is a template specialization

Bug ID: 35302
Summary: missing namespaces when underlying type is a template
specialization
Product: clang
Version: 5.0
Hardware: All
OS: All
Status: NEW

I'm trying to analyze c++ header files using libclang python bindings.
The following example illustrates the inconsistent namespace handling in type
aliases.
Sample C++ code:
-- BEGIN --
namespace n{
class MyClass{
};
template class MyTemplateClass{
};
}
using namespace n;
using MyClassAlias = MyClass;
using MyTemplateClassAlias = MyTemplateClass;
-- END --
Sample output generated by libclang python binding:
-- BEGIN --
kind: 'TRANSLATION_UNIT' spelling: 'c:\namespace_bug.h'
+--kind: 'NAMESPACE' spelling: 'n'
| +--kind: 'CLASS_DECL' spelling: 'MyClass'
| +--kind: 'CLASS_TEMPLATE' spelling: 'MyTemplateClass'
| +--kind: 'TEMPLATE_TYPE_PARAMETER' spelling: 'T'
+--kind: 'USING_DIRECTIVE'
| +--kind: 'NAMESPACE_REF' spelling: 'n'
+--kind: 'TYPE_ALIAS_DECL' spelling: 'MyClassAlias'
underlying_typedef_type.spelling: 'n::MyClass'
| +--kind: 'TYPE_REF' spelling: 'class n::MyClass'
+--kind: 'TYPE_ALIAS_DECL' spelling: 'MyTemplateClassAlias'
underlying_typedef_type.spelling: 'MyTemplateClass'
+--kind: 'TEMPLATE_REF' spelling: 'MyTemplateClass'
-- END --
Namespace is missing from the spelling of underlying type in the second type
alias decl.

[llvm-bugs] [Bug 35311] New: Constexpr constructor of templated class does not require member initialization.
https://bugs.llvm.org/show_bug.cgi?id=35311
Bug ID: 35311
Summary: Constexpr constructor of templated class does not
require member initialization.
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: chmiel...@int.pl
CC: llvm-bugs@lists.llvm.org
The standard requires that "for the constructor of a class or struct, every
base class sub-object and every non-variant non-static data member must be
initialized."[cpprefence.com]
Clang seems to ignore that requirement if the struct is a template.
This behavior is the same regardless of the version and standard.
Minimal example:
template // commenting out this line generates appropriate errors
struct S{
constexpr S() /*: i(1)*/ {}
int i;
};
constexpr S s;
int main() { return s.i; }

[llvm-bugs] [Bug 15481] noexcept should check whether the expression is a constant expression
https://bugs.llvm.org/show_bug.cgi?id=15481 Richard Smith changed: What|Removed |Added Status|NEW |RESOLVED Resolution|--- |INVALID --- Comment #5 from Richard Smith --- Conclusion from CWG discussion: we're going to keep this as-is. "noexcept" has no special rule for constant expressions. It turns out this is actually essential for proper library functionality: eg, if noexcept tries evaluating its operand, then (for example) is_nothrow_swappable is broken by making std::swap constexpr, because std::swap then often ends up getting instantiated before T is complete. As a result of that, I'm also going to consider this change as an effective DR against C++11 and C++14... but I'm open to reconsidering if we see many user complaints. -- You are receiving this mail because: You are on the CC list for the bug.___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs
