This snapshot has been generated from the GCC 15 git branch
with the following options: git://gcc.gnu.org/git/gcc.git branch
What I want to do is: For a nested branch, if the inner branch contains an
array access operation, we need to determine whether that array access will
cause a trap based on its relationship with other array access operations.
For example:
void func1 (int size)
{
arr1 = new int[size];
arr2 = new
Though that does beg the question of whether that is compatible with code
that uses a different format for long-double.

Is there a reason not to remove the meaningless qualifiers? Generally the
rationale for warning about something that has no effect is that presumably
when you wrote it you expected it to do something.

Unicode comparison is addressed by the "stringprep" library.

It’s a little bit of both (error and style). Gcc does warn about
‘set-and-not-used’, and similar, which are technically valid, but in many cases
indication of wasted work. Same here - positioning the strlen inside the
condition, can lead to lot of unnecessary work.
