Exit on signal with a real signal core (+ high order bit set???) instead of our enumerators (which has no meaning outside ROOT).
Fix a comment.
Remove + 128 part since it's just a one particular shell's specific.
We agreed on 139 :) (+ 128).
In -fsyntax-only mode we don't have llvm::Module.
Fix iterators.

Two things first the iterator wasn't considered to be empty.
Second the loop written such assumes chances to the collection
within the loop which is not the case.
Blanks.
Add support for C tentative definitions.
Allow the unloading even in -fsyntax-only mode. At least for verification purposes it is very useful.
In rawInput mode we want to be as close as possible to the compiler.
Blanks.

Prepend cling prefix, which makes the file deletion easier.
Keep the files diff files until the end of the session
Test improvement of the lookup

(should be ignored)
Add a test that loads every clang test and unloads it
Adjust to the test with the correct vars.
FunctionTemplateDecls don't get registered in the lookup. They have templated decls which are the ones that need to be reverted.
Move template handling functions in a separate 'section'
Style.
