Hello, I have written a simple ipa pass and would like to make use of Link time optimisation. My pass requires access to the function bodies and ideally I would like the driver function to be called once at link time and have access to functions in all of the files as if they were one compilation unit. The documentation would indicate that this is possible, but ad hoc instrumentation of some of the other simple ipa passes seems to suggest different behaviour.
My question is whether LTO can be used in this way, to have a simple ipa pass called once at link time with access to the function bodies, and if so how is this achieved? cgraph_function_body_availability seems to only be half the story. I am using GCC 4.6.0 with the gold linker plugin (binutils 2.21).
