[cfe-dev] Integer overflow checking

[Martin Doucha]

Hi,
I've looked at the open projects page and noticed that you're interested 
in run-time integer overflow check generator in CodeGen. Here's my 
CodeGen hack that does just that (even for ++/--, it's not compatible 
with the original -ftrapv implementation though) from my bachelor 
thesis. rtl.c is a sample implementation of abort helper function which 
prints pretty error messages. Other nice checks can be found in my 
thesis project at http://repo.or.cz/w/clang/acc.git

Regards,
Martin Doucha
