[Bug go/83308] Missing platform definitions for SH in libgo
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83308 --- Comment #14 from Oleg Endo --- (In reply to John Paul Adrian Glaubitz from comment #13) > Cacheline size is 32 bytes according to the documentation: > > > www.st.com/resource/en/user_manual/cd00147165.pdf (page 75) Cache line sizes of original SH implementations: SH2,SH2A,SH3: 16 bytes SH4, SH4A: 32 bytes > > PC quantum should be 2 bytes as SH uses a 16-bit instruction encoding. > SH2A and SH-DSP have actually 4 byte instructions. There are also some late SH4A variants which can do 16-bit prefixes, resulting in 4 byte instructions. Other (newer) SH implementations might deviate from the originals and use multiple-length instructions or different cache line sizes. But I don't think that matters a lot. E.g. 68K has variable length instructions and GOARCH_PCQUANTUM=4. Not sure how much the cache line size is of an importance for libgo ... > No idea about GOARCH_MINFRAMESIZE though. > > Patch submitted here: > https://gcc.gnu.org/ml/gcc-patches/2017-12/msg0.html That looks OK. On SH the minimum stack pointer alignment is 4.

[Bug c++/83445] New: conversion function has too high priority in overload resolution
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83445
Bug ID: 83445
Summary: conversion function has too high priority in overload
resolution
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: omawarisan.bokudesu at live dot jp
Target Milestone: ---
In the following program, overload resolution in the
direct-initialization of `target` from `source` (in the main function)
should select `Target(Source const&)` directly,
but gcc 7.2.0 and trunk with -std=c++17 uses `Source::operator Target()` .
I believe the former should be selected because a standard conversion sequence
is always better than a user-defined conversion sequence.
command: g++ test.cpp -std=c++17 -pedantic test.cpp
expected behavior: prints "OK"
actual behavior: prints "Bad"
#include
struct Source;
struct Target
{
Target() = default;
Target(Source const&){
std::printf("OK\n");
value = 0;
}
int value = -1;
};
struct Source
{
operator Target(){
std::printf("Bad\n");
Target target;
target.value = 1;
return target;
}
};
int main()
{
Source source;
Target target{source};
std::printf("v = %d\n", target.value);
}
Using built-in specs.

[Bug libstdc++/83279] std::experimental::filesystem::copy_file can't copy larger files than 2.0GiB
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83279 --- Comment #12 from T B --- Thanks! However, if I understand your code right, you simply fixed the error code, right? So that it is still not possible to copy files larger than 2GiB. Wouldn't it be possible to create a loop in which in each run 2GiB will be copied until (count == n)? To be honest, streams are not my core competence. How is this issue solved in GCC 5.4?

[Bug c++/83441] New: Null this captured in lambda in class variable initializer for templated classes
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83441
Bug ID: 83441
Summary: Null this captured in lambda in class variable
initializer for templated classes
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: alextenbrink at gmail dot com
Target Milestone: ---
Created attachment 42896
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42896&action=edit
Preprocessed compilation result on example
The following code prints '0', signifying that the capture 'this' pointer is
null:
#include
#include
template
struct X {
std::function f{[this]{ std::cout << (void*)this << "\n"; }};
};
int main() {
X x;
x.f();
return 0;
}
Removing the template parameter of the class, or moving the initializer to a
constructor makes the program print a nonzero value, for example:
#include
#include
template
struct X {
X() : f{[this]{ std::cout << (void*) this << "\n"; }}{}
std::function f;
};
int main() {
X x;
x.f();
return 0;
}
My expected behaviour is that the 'this' pointer is not null. It looks like
this problem repos in previous versions of GCC - if I try this code in an
online compiler, I even get internal compiler errors on some sites.

Try sending it to the gcc-patches to see if anyone can test it. I'd try the
patch myself, but bootstrap is currently broken for me.
