RE: Regarding "-z lazyload" flag in gnu linker

["Bhushan Verma" <bhushan dot verma at iap-online dot com>]

Dear Alan,

Thanks for your mail.
As you said this option is not supported in gld.
I have also verified this option in ld/emultempl/elf32.em .
This is not supported in this code.
Now I download the binutils source code from gnuarm site for my arm
toolchain.

I have found the "struct bfd_link_info" ininclude/bfdlink.h
and  "bfd_elf_size_dynamic_sections()" function in bfd/elflink.c.

Now I have one doubt you maen I have to change only these files in this
strucure and function to support -z lazyload.
What shoul be the next step means I have to build binutils,glibc etc

One thig is there any one who alredy do the same as above.

regards
Bhushan

That is true.  Implementing support shouldn't be too hard.  See
ld/emultempl/elf32.em for existing -z support.  You'll need to add a
new field to struct bfd_link_info to pass POSFLAGS_1 around, and
arrange to emit DT_POSFLAGS_1 in bfd_elf_size_dynamic_sections.
