Teach stack promotion to walk the CFG when a potential reuse of an allocation
is found to see if it can actually happen instead of just assuming it will.
This allows it to catch cases like
{{{
int i;
Foo f;
while (cond(i))
f = new Foo(i++);
return f.value;
}}}
where it previously wouldn't because a phi using the allocation would appear in
the condition block to propagate it to the use after the loop.

This should help get the runtime built. FOR D1: ======= 1) Do a checkout of tango trunk into the ldc root dir (along dmd, gen, runtime etc). * $ ls * dmd dmd2 gen ir ... * $ svn co http://svn.dsource.org/projects/tango/trunk tango 2) Compile the runtime * sh build.sh FOR D2: ======= Highly experimental!!! 1) Do a checkout of druntime trunk into the ldc root dir (along dmd, gen, runtime etc). * $ ls * dmd dmd2 gen ir ... * $ svn co http://svn.dsource.org/projects/druntime/trunk druntime 2) Patch druntime * cd runtime * sh patch-druntime.sh 3) Compile druntime * cd ../druntime/src * sh build-ldc.sh ======= Enjoy!
