There probably are.
But at some point, if you are tuning boeh
because that is what the language standard says.
In general, the difference between two global pointers is something
known only to the linker -- too late to evaluate as constant
expression.
In the particular case of two static functions or two static global
pointers, it is possible for the compi
Hi,
I'm trying to extract information from C++ code during the compilation process.
I need information about declarations, statements, functions (including
parameters and symbol name), source line and source file.
In my opinion I have two ways to solve this problem:
1) The first one is to find

But at some point, if you are tuning boehm's to this point, what is the
advantage of it over just writing your own collector like ggc-page? :)
Indeed. That's why I always welcome opinions, should I continue with
Boehm's or stop

This isn't possible with global symbols in a DSO because some other
DSO (or indeed the exe) might also define one of the symbols.
Not with hidden symbols. Sorry, I forgot to mention that.

I noticed that gcc's div-by-constant optimization is a bit
suboptimal and want to improve it. I submitted it to
bugzilla:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28417
but I think "big guys" have no time for such a low-impact thing.
I want to do it myself.
However, I need a little helt in und

Use prelinking. That works for all relocation types, and doesn't
require additional coding.

It helps, but I still have 10639 relocations during a "import gtk" in
python. The relative table also has the advantage that it is constant
and can be shared.

I'll guess that during collection phases, the list of
collectible structures becomes longer.
GCC is just too huge to try and implement reference count

Please try the gcc-help list instead. Also, be sure to check out the
documentation at our web site that explains this in detail. Also,
4.0.3 is old, I'd recommend a newer version as well. Good Luck.
