Gcc plugin: error: ‘LAST_AND_UNUSED_RTX_CODE’ undeclared

Hi,

I am trying to write a simple gcc plugin and am getting the following errors.

In file included from /home/aj/gcc/trunk/gcc/rtl.h:49,

I googled for a solution and found a similar message in which it was suggested to include "tm.h". I verified my code, and I am getting the same error even after including the file.

My CMake file is as follows:

set( GCC_SRC_DIR "/home/aj/gcc/trunk")
set( GCC_BUILD_DIR "/home/aj/gcc/trunk-obj" )
include_directories( ${CMAKE_CURRENT_SOURCE_DIR} )
include_directories( ${GCC_BUILD_DIR}/gcc )
include_directories( ${GCC_SRC_DIR}/gcc )
include_directories( ${GCC_SRC_DIR}/libcpp/include )
include_directories( ${GCC_SRC_DIR}/include )
include_directories( ${GCC_SRC_DIR}/host-i686-pc-linux-gnu/gcc )

I am not able to figure out what is going wrong, can you please guide me on where am I making a mistake?

Thanks,
Ashish

From the looks of it, you have a define for CONST as const.  This
first error is the reason for the rest of the errors.

I havent modified anything in that part of the code. Reordering the header files somehow made all the errors disappear.

You should figure out what is doing the define of CONST then.  Because
from the sound of it, you are going to have problems if you try to use
the CONST rtx code.
