Hi,
I was wondering if anyone could help me make sense of the
more_specialized_fn() function in pt.c (line 13281).
Specifically, I am trying to understand what each of the are:
tree decl1 = DECL_TEMPLATE_RESULT (pat1);
tree targs1 = make_tree_vec (DECL_NTPARMS (pat1));
tree tparms1 = DECL_
Hi,
Thanks for your attention and response. I think I am still not very

from clearly. Now permit me use a simple example, for the simple C

This is not the C % operator. google "ISO/IEC 9899:1999" for a clue.

Does the file build/genmodes exist? If the file isn't there, then you

If the file is there, then this might mean that the interpreter for the

Yes, my earlier message directing you to gcc-help was because I thought
you didn't grasp what the compiler should do and what the linker should
do; sorry about that.

Hi,
I wonder how to let GCC produce flat assembly, say, just like the .com
file under the DOS, without function calls and complicate executable
file headers, only instructions. How to modify the machine description
file to achieve that? Thanks in advance.

There is a config.log file in every directory that gets configured. It
looks like you attached the one from the top-level dir which is not

The issue isn't the ease in which it violates the GPL, but the ease in

No, not in that case, but I don't see that as the only case. Another

Well first of all, that code becomes GPL so the IR isn't truely "proprietary".
