Hmm. Well, if you keep that "memory" clobber there, you don't actually
need to represent the RW memory a
the answer is no, or atleast, nothing that's going to be fixed
anytime soon.
thanks again!

Hello colleagues,
I've come across a suspicious error with inline asm and register allocation,
and am looking for a clarification of the rules.
What aspect of inline asm processing is preventing gcc from allocating
register eax to both %0 and %1's address in the following test case?
gcc -m32

Hi
I am in the process of verifying that gcc (3.3.2) produces traceable
object code (ie. gcc does not introduce 'hidden' structure into the
object code).
I have created a file with several functions containing various
combinations of C constructs and I intend to examine the resulting
object code

Hello,
There are some papers talking about the gcc register allocation in the
summit proceedings. I'd like to know wether the graph coloring
allocator has been used in the gcc-3.4.4. Also, where can I find some
reference of the gcc register allocation, besides the source codes and
