[cfe-dev] Reading LR/FP registers.

[Eyal Retter via cfe-dev]

Hi People,

I am trying to read LR and FP registers address. I have tried calling  the
__builtinXXX API's as well as using assembly directly, using Arm cortex M0
and llvm/clang compiler, C language extension. All I get is zeros. Doesn't
make scense. Is there a special way to do this?
I found information regarding C++ classes but no C info. Can someone refer
me please to the right info?

thanks.

Eyal.
