Subject: cannot build with no-inline-functions
Date: Wed, 31 Jul 2019 16:18:35 +0200	[thread overview]
Message-ID: <CAGdkbuwC8dTTUXdq9TkdH02BkTLmxWob71r0kvxvoubAuRr+2Q@mail.gmail.com> (raw)

Hi *,
I'm analyzing the linux kernel via phasar static analyzer framework,
it basically takes as input an LLVM IR file.
For debugging reasons, I would like to compile the kernel without
inlined functions. I'm compiling the kernel by clang, so I tried to
specify the following compiler flags:

```
-fno-inline-functions
-O1
```

Those were specified via KCFLAGS keyword in the root Makefile, I
generated the compile_commands.json file as well where I can see that
those flags above were used for the building process.

Unfortunately it did not work as I wanted, in the resulting LLVM IR I
still see inlined functions.
Is it possible to avoid inlined functions for the whole kernel via a
compiler flag? or any other suggestions?

thanks,
cheers
