"Is there something unusual (lots of @Inline pragmas? Entire 3000 lines in
a single file?)"
Actually yes. The code is based off of a large, single file, c++ program
that makes heavy use of inlining so there are a lot of @Inline pragmas.
The inlined functions are each called only once in the main program so in
theory it could be done without these function at all by just creating
larger methods but that would create less clean code. Also, I split the
code into 2 files but there are still more than 2000 lines of code in the
primary file. Do you have any idea how to make the code easier for the
compiler to handle without incurring a significant performance impact?
