I think the implementation is still problematic since C++ 20 adds the
contiguous_iterator concept. The current implementation looks not to allow
custom
contiguous iterators types to be optimized as memmove.
It needs certain kinds of revamping IMO.
[Bug c/12245] [8/9/10 regression] Uses lots of memory when compiling large initialized arrays
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=12245 JeanHeyd Meneide changed: What|Removed |Added CC||phdofthehouse at gmail dot com --- Comment #75 from JeanHeyd Meneide --- I would like to add to this post. I experience severe memory usage and compilation time consumption that ramps up heavily when dealing with binary data. I documented much of my struggles here: https://thephd.github.io/embed-the-details I am being told that the functionality I am developing is more suited for a bug report and that this should be compiler QoI. Upon attempting to file this bug, I decided to throw my own data and woes into the ring here. Is there a place I should start looking to help out with this? I would like to start getting closer to the theoretical near-perfect overhead of dealing with what essentially ends up being a large binary payload, without resorting to #embed or any special builtins.
[Bug c++/93093] New: __builtin_source_location reports values for default arguments not aligned with the Standard
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93093
Bug ID: 93093
Summary: __builtin_source_location reports values for default
arguments not aligned with the Standard
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: phdofthehouse at gmail dot com
Target Milestone: ---
Consider the following example from the C++ Standard N4842 (nice website
version: eel.is/c++draft/support.srcloc#cons-4):
===
struct s {
source_location member = source_location::current();
int other_member;
s(source_location loc = source_location::current())
: member(loc) // values of member refer to the location of the
calling function ([dcl.fct.default])
{}
s(int blather) :// values of member refer to this location
other_member(blather)
{}
s(double) // values of member refer to this location
{}
};
void f(source_location a = source_location::current()) {
source_location b = source_location::current(); // values in b refer to
this line
}
void g() {
f(); // f's first argument corresponds to this line of code
source_location c = source_location::current();
f(c); // f's first argument gets the same values as c, above
}
===
When source_location is implemented with __builtin_source_location, code like
the above does not report those locations. s{}.member does not refer to the
calling location, s(2.0).member does not refer to the constructor declaration
s, and s(1).member does not refer to that location, and so forth.
Some talking on IRC revealed that this might be because of constant evaluation
/ constant folding, changing how the source location attribute behaves in
instances like these. This also affects the patch at
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg01579.html whose tests fail in
both static_assert and regular runtime VERIFYs.

TBH. I would rather see the library does the optimization instead of the
compiler. I do not trust the compiler can always optimize this stuff.

I'm fine with either way actually. My main motivation is to have a Rust compiler that supports more architectures than the one currently developed by the Rust develeopers. > And even if yes, can e.g. the runtime library be shared with rustc, > or does it need to be independent? If I understand the approach by "sapir" correctly, this is actually what's being worked on in his gcc-rust frontend: > https://github.com/sapir/gcc-rust/tree/rust > Again, talking about Go, I think the go runtime is shared by all of goland, > gcc-go and gollvm. Which would be perfectly fine with me. I didn't want to leave the impression that a completely independent implementation would be necessary. I just mentioned it because it was brought up as one of the arguments for having a Rust frondend in GCC within the community. I think the approach by "sapir" is actually very promising as it should be able to keep up with Rust upstream which is currently a rather fast moving target.

When actual arguments are passed to a subroutine that accepts polymorphic dummy arguments, the "sizeof" and "transfer" intrinsic functions can return strange results. For example: character(80) :: msg print *, sizeof(msg) ! prints "80" print *, size(transfer(msg,[0_c_int8_t]),kind=c_size_t) ! prints "80" call poly(msg) ! prints "1" and "1" where subroutine poly(obj) class(*) :: obj print *, sizeof(obj) print *, size(transfer(obj,[0_c_int8_t]),kind=c_size_t) end Also, integer :: iary(10) print *, sizeof(iary) ! prints "40" print *, size(transfer(iary,[0_c_int8_t]),kind=c_size_t) ! prints "40" call poly1(iary) ! prints "40" and "80" where subroutine poly1(obj) class(*) :: obj(:) print *, sizeof(obj) print *, size(transfer(obj,[0_c_int8_t]),kind=c_size_t) end See attached file for complete code that demonstrates these problems. The documentation for "sizeof" states that "The argument shall be of any type, rank or shape" and further, that "If the argument is polymorphic, the size according to the dynamic type is returned." Similar statements apply to the "transfer" intrinsic. The size for assumed-shape dummy arguments should be known, but inconsistent results occur as described above. Admittedly, the size for assumed-size dummy arguments may not be known.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93066 --- Comment #2 from Jakub Jelinek --- (In reply to dave.anglin from comment #1) > Including stdint.h after inttypes.h would avoid the problem That would be quite difficult, as stdint.h is included by libgomp.h that needs to be included first. An easier workaround might be not to use the UINTPTR_MAX macro at all, I think we can rely on uintptr_t being unsigned integral type and so instead of if (n->aux->attach_count[idx] < UINTPTR_MAX) we could use if (n->aux->attach_count[idx] + 1 != 0)
