Hi,
I'd like to add some source and header files into gcc. I think I
probably need to make some change in Makefile.in. But the Makefile.in
looks very complicated. Could anyone give some advice on this?
Regards,
Haibin

No. You've already asked, and it's already been answered, with
langauge from the standard. What more do you want?

Dear gcc@gcc.gnu.org,
Your question was not submitted to the helpdesk because of a problem:
You need to register online at http://ccgi.rowley.co.uk/support/ before you
can submit new questions via e-mail.
Why is this? To provide better tracking of user issues and because we need to

Thanks to Ben, I've already posted the same question to

Hello!
The new scheme to select target tools breaks building GCC for me. Maybe I
have an unusal setup. The problem in my case is that configure now chooses
tools from $prefix/bin. It did use tools from $prefix/$target/bin before.
On my setup I have *different* tools in those places. Until know the

It looks to me like this last changed around 2005-06-16 on HEAD, and we
assume that the assembler installed in $prefix is the assembler you
want the compiler to be using - it's the same assembler you'd get if
you said "as", so why shouldn't we use it?
When building from a combined tree, I sti

Hi all,
Have the keywords 'auto' and 'decltype' already have been implemented?
- as described in

- for easier use of template expressions.
I have difficulty to find information concerning this problem.

Hi,
It appears GCC 3.x no longer supports the
-fvtable-thunks option. Is gcc 3.x using thunks by
default for its vtable format? Also, can the
_G_USING_THUNKS macro no longer used to determine if
thunks are being used?
Thanks,
John

Is there any way to tell cse how many times a value gets reused before
putting a copy in a register is profitable? The logic seems to
compare the address costs, but doesn't account for the cost of storing
in the register. What I'd like is some way of saying the cutoff is N
uses, not the current
25 matches
