llvm dev - Feb 2011 - [LLVMdev] What are the equivalents of gcc inline control options like max-inline-insns-single in clang?

I got these warnings:
clang: warning: argument unused during compilation: '-finline-limit=50'
clang: warning: argument unused during compilation: '--param 
max-inline-insns-single=50'
clang: warning: argument unused during compilation: '--param 
max-inline-insns-auto=12'
clang: warning: argument unused during compilation: '--param 
large-function-insns=300'
clang: warning: argument unused during compilation: '--param 
large-function-growth=20'
clang: warning: argument unused during compilation: '--param 
inline-unit-growth=100'

These options work with gcc and not with clang.
What are the clang equivalents?

Clang doesn't expose any equivalent.

Why not?

Such controls are useful to tune the level of optimization. For example 
from my experience forcing more inlining causes code to grow due to 
resulting duplication but often such code is also faster. Even though 
cache mishits may cause it to slow down too eventually. Speed is vital 
for software in many industries.
User should be able to force-flatten the module leaving only interface 
functions. On the other hand user may want to lower the inlining level 
to speed up compilation.
