Hi,
I recently discovered that the following C statement:
pointer++;
is semantically equivalent to the following:
*pointer++;
Is this due to operators' priority? To me, that looks weird.
Thanks in advance,

was solved by checking if it is installed makeinfo >= 4.8. I am using

Do you have any recomendations for me ?

In the .md-file of my port, I have set an attribute "size" of every
insn, giving its size (obviously), in bytes. Is there any way I can use the
value of this attribute to determine the cost (in e.g. TARGET_RTX_COSTS)
when optimizing for size? Or is there some other smart way of achieving
the same t

Ok. Do you know of any other reasons why this particular optimization
switch would cause this problem?

I am still porting gcc v4.1.2 to a new risc architecture, and this
time my problem is that when compiling with -O2 turned on, every insn
with a (use ..) side effect expression, eg.
(define_expand "sibcall"

Ok, do you have any idea about what might cause this
I am porting gcc to a new architecture, and have yet another problem
that I've been staring at for far too long now.
Whenever I compile a program that calls malloc, GCC crashes with:
/cygdrive/c/home/risc/src/gcc-4.1.2/gcc/unwind-dw2-fde.c: In function
'__register_frame':
/cygdrive/c/home/risc/sr

You're right, and getting REG_OK_STRICT right solved the problem!

I am porting GCC to a new target, and got the following error when
cross-compiling libgcc towards the end of the make process:

Thanks a lot for your input, I think I understand some of that code better now.
I stumbled upon a solution last night, on realizing that the problem
was with the DFmode powidf2 and seeing that I had not defined the
movsf or movdf insns (because I thought I shouldn't need them, having
no HW floatin

I am porting gcc to a new target architecture, and have come across a
problem when the make process tries to compile libgcc. The error I get
is included below.
It seems that gcc has emitted rtl describing a memory reference (mem

Hi,
I found out that page http://gcc.gnu.org/svnwrite.html points to
http://gcc.gnu.org/ml/gcc-SVN/ mailing list but it doesn't exist. It's
in section "Write access policies" above "Free for all" subsection.
It seems that correct list is http://gcc.gnu.org/ml/gcc-cvs/.

Hi,
I am working on some gcc patches (now profiling indirect/virtual
calls and it's devirtualization) and i would like to contribute it to
gcc. I've read that i must sign some forms for contributing. Could you
tell me where can i get it ?
Thanks
