Gcc plugin: error: ‘LAST_AND_UNUSED_RTX_CODE’ undeclared

[ashish jain]

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

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

Help with gimple_build_call

[ashish jain]

Hi,

I am writing a pass in which I need to insert a call to a library
function. Specifically I need to call the function
"pthread_mutex_lock" from the library "pthread". I am working on
GIMPLE, specifically after the "build_cfg" pass.

Looking around the documentation, what I found is I will have to use
the function gimple_build_call. My question is how do I build the tree
fn, and the arguments which have to be provided to gimple_build_call.

Do I have to use build_function_type_list and build_fn_decl for
building tree fn? The original function call "pthread_mutex_lock"
requires an "pthread_mutex_t" type variable as an argument, how can I
declare that in the pass, and use it as an argument in
gimple_build_call?

Thanks,
Ashish
