I'm working on a vulnerability detection pass for GCC, using a combination of
taint and value range propagation. The first version of the code (and a paper
describing the approach) is available at http://gcc.vulncheck.org/
The tree-ssa infrastructure was very useful for implementing this type of

Hello,
I get the following error while running make BOOT_CFLAGS='-O2' bootstrap
on ppc64 with --enable-checking on r128689:

Hi,
I would like to implement a type-based operator (like sizeof, alignof,
etc.) for mingw32 / cygwin targets, which allows to interprete type-based
attributes. For DCOM support it would be helpful to have the __uuidof

Yeah. I am now using --with-cpu=default32 at configure time. That
seems to fix things enough to get libstdc++

There is probably something else happening with -O that is recomputing
some liveness or CFG info. For instance, the flow2 pass w

IL stands for Intermediate Language. Sorry.
