Yes, it is a bit unfair. People are not treated as who they are,

Hello,
For the targets that support vectors, we can write the following code:
typedef short V4H __attribute__ ((vector_size (8)));
V4H tst(V4H a, V4H b){
return a + b;
}
Other operators such as -, *, |, &, ^ etc are also supported. However, vector

Hi,
even if I am simple mortal I would like to understand or at least follow
what is going on with gcc.
Generally when I run gdb and try to breakpoint inside a function I get a
undefined symbol or something like that.
I suppose this is because gcc is not a simple static exe but depends on
other bi

Did you compile with -O0? A function may be inlined and a symbol may be
optimized away with -O1 and above.

Hi,
On attempting a bootstrap of trunk r144402 with --enable-languages=c,ada,c++
using gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)
on i586 I get:
gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings

The requirement is GCC >= 3.4
This is documented at: http://gcc.gnu.org/install/build.html
('Building the Ada compiler'), except that the online version matches GCC
4.3, not trunk. The trunk version (gcc/doc/install.texi) reads:

Hello,
We are trying to locate someone from the gcc community in the U.S. who is
experienced in modifying and building gcc 'C' compilers.
We looked through http://www.gnu.org/prep/service.html ,but were
finding a lot of the links are outdated or they no longer do this kind of
work.

I was just entirely unable to get 3.4.4 to bootstrap a 4.3.2 compiler. I
used 4.3.0 and it worked. I forget what I used to build the 4.3.0 with in the
first place. I think the documentation needs updating to say you'll need to

Yes, at least the first case (scalar operand 2) is supported by valarray.

Additionally, if we follow valarray guideline, GCC should also support code
like:

Yes, I am aware of both types of vector shift. Our target VLIW
actually supports both and I have implemented all related patterns
in our porting. But it would be still nice to allow programmer
explicitly use vector shift, preferably both types.

Actually, http://gcc.gnu.org/install/ is the latest from SVN on a
nightly base. (I checked the crontab we have on gcc.gnu.org to be
sure.)
