Re: LLVM as a gcc plugin?

Hi Rafael,

There was some talk about it on #gcc. A plugin should be able to see
all the GCC IL, so it should be able to convert it to LLVM. Keeping
the current llvm-gcc interface would require some hacks

*) The plugin will have to call exit to keep gcc's code generation from running. 

this would work when doing unit-at-a-time, but not when doing
function-at-a-time.  Does gcc still do function-at-a-time?

Another source of problem will be the early transformations that gcc
does and that are normally disabled in llvm-gcc. The one that I
remember right now is c++ thunk generation.

Good point.

Ciao,

Duncan.
