Gcc Plugin: error: ‘FIRST_PSEUDO_REGISTER’ undeclared

[Aravinda]

Hi,

Im compiling a simple gcc plugin and am getting the below error.
I cant figure out whats wrong, but looks like, my Makefile is not
right. Can you please tell me what is wrong ?

[aravinda@localhost backup]$ make

I think that for the time being it is OK to ask questions about
compiling plugins on the gcc@gcc.gnu.org mailing list.  More of the
plugin developers read gcc@.  Of course it's always OK to ask questions
on gcc-help@ as well.  (Don't send a message to both mailing lists,
though.)

You have to #include "tm.h".  A lot of gcc header files assume that that
has already bee done.

Thanks a lot. That worked.
