Hi.
I have a program that uses computed gotos.
Should I use -fno-gcse?
The situation is that there is one very important function with computed
gotos and about 300 others without!
Isn't there a way to disable fgcse for that one function and allow it for
the rest of the code?
With fno-gcse the program is about 0.3% faster, so I can't tell for sure
what's the right thing to do here.
Help!
gerald.
