Re: [PATCH, ld/ARM, ping] Mark bare-metal ARM targets as not supporting shared libraries

[Thomas Preudhomme <thomas dot preudhomme at foss dot arm dot com>]

Hi Alan,

I'm glad you ask. In general arm-none-eabi targets being bare metal do not have 
a loader to deal with shared libraries. However GNU ld itself does indeed does 
have the support for shared library when built for such targets.

Having discussed further with my colleagues I now believe that this patch is not 
appropriate. So far the only test that fail are link-time only, they do not 
involve runtime. It is thus better to look into these failures. This can be 
revisited later if a shared library runtime test is added at some point in the 
future.

Thanks for chimin in and sorry for the noise. Best regards,

Thomas
