Very strange thing: I'm writing a CDEF resource in C. When I put

#pragma always_inline on

near the top of my file and attempt to build, the compiler seems to
get caught in an infinite loop. It just sits there compiling, with the
little gear icon spinning next to the source file icon in the project
window, but it never finishes. It's a very small project (450 lines,
including comments -- and my coding style uses lots of line-breaks, so
that's probably more like 300 lines of "normal" code). Without the
#pragma line, the target compiles and links in about 2 seconds; so I'm
quite certain that the compiler really is hanging, and not just taking
a long time.

Any idea why this is happening and how I can prevent it?

Do you have a recursive function or a mutually recursive pair of 
functions?

I'd be interested to know if there is a case statement involved they 
take a long time to inline.   Have you walked away and came back and to 
see how long it takes.  If you have full optimization on, a level 8 
inlining and always inlining on it could take quite a while if there was 
a case statement.

If you could send a bit of code that shows this we could tell more.  
Perhaps the compiler is falling into some loop somehow.

I'd also be curious to how long it takes if you add this 
#pragma inline_bottom_up off

with the always_inline

A watched source file never compiles? :-)
