I am using the llvm 1.9 and contrary to the help page there is no option:
Help page is for 2.0cvs. If you're using 1.9 you should use
for the command "opt". It would be nice if s.o. could list the passes which
are normally done for compilation/optimization.
You can see full set of optimisations performed by llvm-gcc in many
1. findmisopt script
2. Comments in 1056 – Should document gcc 3.4.4 as known-broken on x86-64
PS: Is there some overview over all the passes besides the documentation in
the head of the source files? Being not so fond with compilers i am somehow
lost with all theses passes.
AFAIK, it's in progress.
