Two reasons:
1. The C++17 standard refers to the C11 standard.
2. C11 is sufficiently modern while not closing doors for users
requiring compliance with an "older" standards. That said, we could
choose not to implement certain items removed in the C17 standard. An
obvious example of suc...

'crunchers' are Xubuntu 64b (v8.04 except one v7.10), one of the

by my employer and my 'main' desktop(C17). Two of the Xubuntu
'crunchers' (C19 & C20) have Samba running in a very simple, un-secure
mode to share up some backup drive space and some generic network
storage. One of those (C20) also serves as an apt-cacher.

The value of padding when storing an aggregate into memory
Hello all,
LangRef isn't clear about the value of padding when an aggregate value is
stored into memory, and I'd like to suggest that storing an aggregate fills
padding with undef.
Here are a few clues that supports this change:
- According to C17, the value of padding bytes when storing values in
structures or unions is unspecified.
- IPSCCP ignores padding and directly stores a constant aggregate if
possible: https://godbolt.org/z/ddWq9z
Memcpyopt ignores padding when copying an aggregate or storing a constant:

Understand alias-analysis results
Hello,
I am performing alias analysis toward the following simple code:
struct MyStruct {
int * f1;
int * f2;
};
void NOALIAS(void* p, void* q){
}
int main() {
struct MyStruct s[2];
int a,b;
s[0].f1 = &a;
s[1].f1 = &b;
NOALIAS(s[a].f1, s[b].f2);
return 0;
}
When I use the following command to generate .bc code and conduct alias
analysis:
