Hello,
I am preparing the submission of a patch series to support the FDPIC ABI for
Linux on ARM.
During development, we internally used arm-linux-uclibceabi as target name, but
I had to change it to handle feedback when I submitted the binutils patches.
These have been merged to binutils master, and use arm-uclinuxfdpiceabi as
target name.
Changing the target name in binutils was a bit painful, but the equivalent
change in GCC is more invasive: to get the same testsuite results we had with
arm-linux-uclibceabi, I not only had to update several tests to accept the
additional target, but I also had to edit several configure-related files to
activate the same paths we had validated with the previous target name.
Roughly speaking, it is a matter of extending cases where we try to match
$target or $host against *-linux*, or $host_os against linux*. In all these
cases I conservatively chose to add arm*-*-uclinuxfdpiceabi or uclinuxfdpiceabi
to avoid side-effects on other uclinux targets.
I have attached the patch that handles that in the series, to check if this
will be acceptable. Indeed, I am surprised by the number of changes involved,
and I thought most of the enablement had already been done on other uclinux
targets.
Thanks,
Christophe
