Hi Matthew,
One thing you might want to consider doing is adding a test to verify
Kalimba ObjectFileELF parsing doesn't regress using this test here:
test/functionalities/object-file/TestImageListMultiArchitecture.py.
Essentially you start by looking under that test's bin/ dir. You'll see a
hello.cpp file and several exes built on different platforms (checked in)
that represent valid object files for that platform. You could go into
that directory and do something like this:
/your/compiler/exe -o hello-kalimba-{kalimba-version}-{your-compiler}
hello.cpp
Then edit the TestImageMultiArchitecture.py file, and add an entry to the
table that specifies expected image list output for your exe.
The idea here is that, if we get a test that correctly identifies a kalimba
file and have that checked in, we'll get a heads up if any other changes
(likely changes to ObjectFileELF.cpp) end up unexpectedly breaking Kalimba
object file support.
If you can get that together, I'll gladly help you get that checked in.
For this test, there's no reason to generate copious debug info since all
we're really validating is the ObjectFileELF platform recognition. I built
all those exes in there optimized for small file size since we check in the
exe (well, not including -g on the compiler line in particular).
Thanks!
-Todd
