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

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,

Since you CC'd me, what makes arm-none-eabi different to other ARM
targets that do support shared libs?  I don't see anything different
in bfd, and ld/emulparams/ says GENERATE_SHLIB_SCRIPT=yes.
