Hello,
What are exactly GCC code types, defined in gcc/coretypes.h?
Of course, they are very important types used in GCC. And there are
probably wired in gengtype (but maybe not all of them; I didn't check
for all; certainly gengtype handle tree & gimple specially in some
way.).
However, I don't

Hi Basile,
Assuming a plugin (e.g. MELT) add a new pragma using PLUGIN_PRAGMAS, is
this pragma usable from Ada or Fortran code?
I am not very familiar with Ada or Fortran. I believe Ada has some
syntax for pragmas -but do Ada pragma have the same API inside GCC
plugins as C or C++ pragmas?- and

Perhaps a easy way to solve the problem would be to claim for branches a memory
port a number of stages before and after the IF; to avoid in this way ha

The Ada front-end is entirely isolated from the middle-end so we would need to

Hello all,
When I try to compile GCC (trunk revision 161164). It seems that gcc is waiting
for reading on stdin after libgcc2.c.
This is what I get :

The main purpose of putting types in coretypes.h is to separate interface
from implementation. See the comments in that header.

After two ./contrib/gcc_update, the bug disappeared. With Basile, we noticed
that cc1 didn't work for a couple of hours when invoked as ./cc1 id.c where
id.c is trivial.

Hello,
I have a question regarding code generation for a new target I'm working
on.
I am using GCC 4.6.
In reload pass the following first instruction is replaced with the
second one after spilling reg 182 to the stack. The problem is that
the generated new instruction does not have a valid ad

Hi,
Is there any project for translations between GCC RTL and LLVM SSA,
RTL -> SSA and SSA -> RTL? I am working on a project that may reuse
existing optimization passes from LLVM and GCC. So I was wondering if
there is a way to switch between their IR's.
Thanks.

A bit of thread hijacking (moving it to gcc@) I'm afraid, but
it's too related to pass up on the opportunity...

Hi:
At last of function change_loop, gcc try to change ALLOCNO_REG of
local allocno.
In the loop, ALLOCNO_SOMEWHERE_RENAMED_P (allocno) is set if allocno is not
caps.
Don't understand why the flag is set here. Doesn't all local allocnos'
flag are set in this
loop? seems conflicting with function
