File copyright assignment | GSOC 16

[Ayush Goel]

Hi,
I have been selected for the google summer of code ’16 with GCC. I’m required 
to file a copyright assignment before I can start making  contributions to the 
project.
I would like to obtain the relevant forms in order to contribute to the gcc 
project. 
 
Thanks,
Ayush Goel

Hey,
I wanted to introduce myself to the gcc’s developer's community.
I have been selected for the google summer of code program with gcc for 2016.
The title of my project is - Replace libiberty with gnulib

I’ve created a very short wiki describing the project and my initial approach 
at how I’ll be proceeding. 
https://gcc.gnu.org/wiki/replacelibibertywithgnulib

Any kind of suggestion or criticism to the approach mentioned will be highly 
appreciated. 

It’s a pleasure working with gcc.


- Cheers

Importing gnulib inside gcc

[ayush goel]

I’m working on importing gnulib inside gcc so that gcc can leverage it’s 
functionality (and possible replace certain dependencies from libiberty). 

I have imported the required gnulib modules in a directory inside the gcc 
directory, along with the necessary configure.ac and Makefile.in required to 
configure and compile gnulib. 

In order to invoke these from the top directory, I’m making the corresponding 
changes in gcc/Makefile.in and gcc/configure.ac 
However the build is giving me an error (specifically it is not able to find 
the libgnu.a file). I’m not sure why this is happening.
I’m attaching the changes that I’ve made in the configure.ac and Makefile.in 
files

Thanks,
Ayush

Should we import gnulib under gcc/ or at the top-level like libiberty?

[ayush goel]

Hi,
I am working on importing gnulib library inside the gcc tree. Should the 
library be imported in the top level directory along with other libraries (like 
libiberty, libatomic, liboffloadmic etc), or should it be imported inside gcc/ 
like it is done in the binutils-gdb tree. There they have a gnulib directory 
inside gdb/ in the top level directory.

Importing gnulib in gcc

[ayush goel]

I’m using the whole of gdb’s gnulib wrapper library and scripts and imported it 
in gcc's top level directory. 
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=tree;f=gdb/gnulib;h=cdf326774716ae427dc4fb47c9a410fcdf715563;hb=HEAD
 

I’ve also added gnulib as a host and build module in the Makefile.def and added 
the corresponding dependency of all-gcc on gnulib targets and regenerated the 
Makefile.in and configure files.

However I still don’t see compiled gnulib files as a sub directory in the build 
directory? 
What can be the reason for that?

Build fails on importing gnulib

[ayush goel]

Build fails on including gnulib header files in the include path

In file included from insn-modes.c:5:
In file included from /Users/ayushgoel/gsoc/src/gcc/system.h:294:
../gnulib/import/unistd.h:135:3: error: "Please include config.h first."
 #error "Please include config.h first."
  ^
../gnulib/import/unistd.h:137:1: error: unknown type name 
'_GL_INLINE_HEADER_BEGIN'
_GL_INLINE_HEADER_BEGIN

I’m assuming after the newer version of gnulib it is required to include 
config.h before the system headers.
However config.h has already been included before system.h in all such files. 

Is this due to some variable like HAVE_CONFIG_H being set?
