Please verify that it indeed does not change the code. Feel free to commit it yourself if you want to, or I'll do it on your approval. What I use to verify no code changes is: $ make -j... # build before applying patch $ mkdir =stock $ cp libc.so =stock/ ... apply the patch ... $ make -j... # build after applying patch $ diff -u -I '.*file format.*' <(objdump -rd =stock/libc.so) <(objdump -rd libc.so) Thanks, Roland * sysdeps/unix/sysv/linux/tile/arch-fork.h: New file. * sysdeps/unix/sysv/linux/tile/nptl/fork.c: File removed. --- /dev/null +++ b/sysdeps/unix/sysv/linux/tile/arch-fork.h @@ -0,0 +1,29 @@ +/* ARCH_FORK definition for Linux fork implementation.
