MT_CFLAGS

MT_CFLAGS

[Aleksandar Ristovski]

Hello,

I see that MT_CFLAGS is gone from Makefile.in. 

What is the alternative to getting the same result? I need to add a target
specific #define to CC, e.g. -DMY_DEFINE. What is the correct approach?

Thanks,

It was removed because we try not to add target-specific defines any
more.  What do you need it for?

Normally proper use of gdbarch and target inheritance is enough.

If this is needed for building a native debugger, the correct approach
is to add an autoconf "check" that results in the right symbol being
defined in config.h.

If this is needed for building target-specific code, you're doing
something wrong.  The code for that should not depend on any
predefined symbols.

If it's for local changes, there's plenty of ways to do it.  For
instance, specify them in CFLAGS when running configure, or add a
local line to the Makefile.in.  Or have the main configure script
define something based on $target if you want to be able to test
without them easily.

I want to implement some fix-ups (workarounds) that are really specific to
us and have to be made in gdb files (not ours). The workarounds are not
candidates for mainstream, so I am wrapping them in our #ifdef-s... No big
deal really, I just thought there was a 'correct' way to do it. 

But maybe you have some other suggestion?

Thanks,
