Hi Kugan,
Since arm compiler 6 support LTO now, I would like to know some basic
information about LTO compared with GCC support. No real use case now. Thanks
for your reply.

Hi David,
LTO support is present in the toolchain for some time now. GCC support
was added in GCC 4.6 and it was continuously improved. Necessary LD
support also was added in GNU LD 2.21. Therefore any recent toolchain
should be fine. Did you run into any issues using LTO?
Thanks,
Kugan

Hi Team,
Could you please let me know which version of toolchain released from Linaro
starts to support LTO? Thanks
David

Note I rather see split stack support than ld -r LTO support done. I think
most enterprise folks would too.

Hello toolchain gurus,
In the course of Linaro's kernel tinification project, the ability to
compile the Linux kernel using LTO is a frequent requirement. However
the kernel makes heavy usage of 'ld -r' with .o files resulting from LTO
build of .c files as well as .o files resulting from pure a
