Hmm, do not forget to revert the switch after being done:

   svn switch http://llvm.org/svn/llvm-project/llvm/trunk .

Also, you will need to do these conversions to llvm-gcc:

##### tcsh script follows ######
foreach CLASS (GlobalVariable)
setenv SUBST1 "s/new $CLASS/${CLASS}::Create/g"
setenv SUBST2 "s/new llvm::$CLASS/llvm::${CLASS}::Create/g"
foreach i (`find . -name "*.cpp"`)
sed -e "$SUBST1" -e "$SUBST2" < $i > $i.2
rm $i
mv $i.2 $i
end
foreach i (`find . -name "*.h"`)
sed -e "$SUBST1" -e "$SUBST2" < $i > $i.2
rm $i
mv $i.2 $i
end
end

In one place you will have to undo the change (compiler will tell
where).

You can also experiment with removing User::U (and the related
asserts).

Cheers,
