Summary: [11 Regression] Many targets failing ssa-dom-cse-2.c

Hi all,
I am studying C++ modules and, especially, trying to understand how
implicitly instantiated template specializations are exported.
I encounter an example where GCC and Clang behave differently.
For example:
/* mod1.cpp */
export module mod1;
export {
// function template

What about adding another check when BUFSIZ is smaller than 4KB? If it is
smaller than 4kb, adjust the filebuf size to 4kb at least.

The C++ parser already tracks function call parens matching, but the C

a testcase showing the C++ and C parser matching function call parens

Hello world,
this patch fixes a 8/9/10/11 regression, where finalized types

Overview:
=
This performance difference appears to affect many versions of g++: my testing
indicates since g++ v7.3.0. The performance difference appears to be a 4-7x
difference in the time taken to compile
Now tested in C++98 mode, there was indeed a small problem.
I even wonder if I shouldn't have extend the std::copy overload to any
call with deque iterator as the output so that it is transform into an
output to pointer.
Ok to commit ?
