GNU ar only uses a flat module (object) name space but supports multiple
instances of objects with the same name. As we use subdirectories with
source file names that may clash (e.g., signal/common.cc and
server/common.cc in the base library) some of our static library
archives have multiple object instances. This is not an issue on archive
creation but works not as expected when updating archives. To avoid
updates of library archives we delete the files before calling GNU ar.
Rust relies on atomic builtins, which are not implemented in libgcc for
ARM. One is implemented in rust, which is sufficient to get the
current rust test to run.
Issue #1899
The new 'select_from_ports' function allows a target description file to
query the path to an installed port. All ports are stored in a central
location specified as CONTRIB_DIR. By default, CONTRIB_DIR is defined
as '<genode-dir>/contrib'. Ports of 3rd-party source code are managed
using the tools at '<genode-dir>/tool/ports/'.
Issue #1082
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
