[omr-dev] Question regarding TreeTops

[Dibyendu Majumdar <mobile@xxxxxxxxxxxxxxx>]

Hi,

I see the following line in
https://github.com/eclipse/omr/blob/master/doc/compiler/il/IntroToTrees.md:

> Testarossa's IR manages side effects using symbol information. Any node producing or affected by a side-effect must have a symbol.

I wanted to understand more what above means. What is a 'symbol' here?

An 'return' instruction is a TreeTop I believe? If the IL returns an
integer constant, how is it related to a symbol?

Thanks and Regards
Dibyendu
