Hey, As a first step of my GSOC project (https://gcc.gnu.org/wiki/replacelibibertywithgnulib) I have imported the gnulib library inside the gcc tree. I have created gnulib as a top level directory which contains the necessary scripts to import the modules. It also contains the necessary Makefile.in and configure.ac files. I have made the corresponding changes in the Makefile.def and configure.ac files, adding gnulib both as a build and host library, and subsequently regenerated the Makefile.in and configure files.
In order to show the setup works, I’ve replaced libiberty’s version by obstack by gnulib’s. This was made possible by replacing the corresponding header file and then including gnulib headers and gnulib static library in the build path required to compile gcc files. Also, in order to ensure that the setup works fine, I locally removed obstack.[ch] from libiberty so that the setup uses the corresponding files from gnulib Used gdb’s scripts to import gnulib https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=tree;f=gdb/gnulib;h=cdf326774716ae427dc4fb47c9a410fcdf715563;hb=HEAD Bootstrapped with multiple languages and multilib enabled for maximum coverage.
