I have been told that openMP does parallelizing of loops, but these

I ran into a little issue when trying to force inlining with

the compiler to inline my code is simple: I want to implement handwritten

Hello,
I ran into an issue with the LTO merges when updating to current trunk.
The problem is that my target calls a few functions/uses some data structures
in the gcc directory: c_language, paragma_lex, c_register_pragma, etc.

That exactly is the problem. You can't have a CONST_INT inside a
ZERO_EXTEND. That is not valid.
You'll need a separate pattern to recognize the CONST_INT without a
ZERO_EXTEND around it. Unfortunately, this will not give reload
the freedom it should have.

I'm new to the GNU tool building environment.
