Gcc and a Garbage Collector.

Gcc and a Garbage Collector.

[Stephane Wirtel]

Hi, 

With this page from Wikipedia, http://en.wikipedia.org/wiki/GNU_Compiler_Collection, in the "See also" section, 
there is a sentence about a Garbage collected included in GCC.

Is it true ?

If yes, how can I use it with my c++ source code ? (documentation,
articles, tutorials...).

Thanks


Stephane

It is a very simple mark and sweep GC and not realy useful for most other projects.
You mark each struct for GCable and all static and global variables too.  You cannot
have only a reference to a GCable on the stack (it has to be in a GC marked variable
too) when the gc is called.

Thanks, 

And in the gcc documentation, can you tell me where can I find an
example or a description ?

There's also boehm-gc:

http://www.hpl.hp.com/personal/Hans_Boehm/gc/

which is shipped with gcc for java's use.

Mostly depends on what you're looking at the gc for - whether it's  
for your language, for hacking on gcc, or something else.

in the internals manual of GCC, it is part of the sources of GCC and  
nothing
else.  You can pull it out and use it in a different project but that  
would
very stupid.

Anyways the docs are:
http://gcc.gnu.org/onlinedocs/gccint/Type-Information.html#Type- 
Information
