The first two sentences of your comment was never disputed by either myself nor
from how I read Mr Torvald's comment.
The only thing under dispute is the completely unwarrented trnasformation of a
subtraction into

A standard is a __treaty__ (contract) between implementor and programmer.
And in our implementation, there is a library for support functions. If you
don't see that, then please stop your rants. Your rants

A treaty is a bilateral agreement. No something shoved down one Side throat.

1) The compiler needs a support library to implement all required features in
the standard.
2) That library is libgcc.
3) Linux kernel has its own support library for these functions
4) The linux kernel support

As I am clearly rejected by the GCC insiders in my attempts to help make the C
compiler more attuned to the spirit of the C99 committee; I am now forced to
alert the user community of what is happening with a near

How many times do I and others, GCC is doing the correct thing?
If you want to ping someone, go talk to Linus.

When I am saying GCC is doing the correct thing, I am talking about the library
issue and not about the code gen issue (the code gen issue is filed in a
different bug and will be fixed, it just takes time though

Segher was mentioned twice. First, according to my research he is not a kernel
maintainer as implied in comments 4 and 9. He is actuallu Segher Boessenkool, a
GCC maintainer, inactive since 2005-02-01, his latest

Hello anyone in here? I guess you did not see my comment about the code gen
issue is going to be fixed. The issue with the library is a different problem
and not really an GCC issue and that if the programer uses

As mentioned many times, libgcc is correct and the issue with the libgcc is a
kernel issue. Yes GCC should not be emitting udivid3 in the case of the loop
but that is a different bug which is still open.

Again please read What I wrote about what the C99 standard requires. It
requires long long support for a freestanding compiler. So that is provided
with libgcc. If the Linux kernel team decides that they don't

Mr Pinski! Thanks for again doing the work for me.
I just had to take some time out for my annual checkup and to rebuild my big
machine's software after Gentoo on shutdown -h now deleted my /bin, /etc, and

You need to learn this is not a bug.
if you do:
long long f(long long a, long long b)
{
return a/b;
}
You will get a reference to divdi3. There is no bug here except inside the
lInux kernel.
Linus is wrong in

Huh? This bug is invalid. Linus is incorrect. Please read all the emails
including Segher's. Note GCC is not ignorining unlikely at all (except maybe
for a code size issue).

Also by the way the divide is only inside the unlikely part of the code so it
will not slow down the common code.

The problem again is in the Linux kernel.

Now you are getting annoying. Richard closed the bug already too. Please read

produced except for the fact GCC is emitting a call to divdi3

The standard is clear that long long is fully supported by freestanding
programs which means that the implementation needs to support it. GCC supports
it by providing libgcc.a support library.
