Re: [Patch, AARCH64] gc-section support

Hi Venkat,

Thanks for the patch.

Can you please generate the patch using "diff -u -p"? This will make the patch easier to review. Also the indent is not consistent with the existing style, which is hard tab(s) plus spaces. Can you please correct it as well.

Thanks,
Yufeng

Hi Maintainers,

Attached is a small patch that enables gc-section support for AARCH64.

In the sweep hook I have handled TLS and GOT related relocs that were
already supported in that file.

Make check passes along with the gc-section tests.

I used the patched binutils to build gcc for aarch64-none-elf target
and tested the gcc testsuite in v8 foundation model.

Ok for trunk?

regards,
Venkat,
