.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
This patch unifies the core-internal 'Mapping' type across all base
platforms.
As one minor downside on seL4, the diagnostic error messages when
observing faults other than page faults no longer print the faulting
thread and PD names.
Issue #2243
Do not link base and core libraries into on large relocatable .o file,
which is linked later to core - causing long link times. Create an
independent library archive out of the base and core libraries that can
be linked faster.
issue #4027
This patch simplifies the use of ccache with the build system. Up until
now, each developer had to set up the ccache hooks manually, adjust the
PATH variable, and customize the etc/tools.conf in each build directory.
With the patch, ccache can be enabled by un-commenting a single line in
the etc/build.conf file.
Fixes#4004
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
Adjust the base-* platforms to acknowledge new thread location solely if
migration is supported and succeeded. Otherwise the wrong thread
locations are observed via the trace session and utilization time calculation
get wrong.
Issue #3842
- base/cancelable_lock.h becomes base/lock.h
- all members become private within base/lock.h
- solely Mutex and Blockade are friends to use base/lock.h
Fixes#3819
This patch largely reverts the commit "base: lay groundwork for
base-linux caps change" because the use of 'epoll' instead of 'select'
alleviated the need to allocate large FD sets, which motivated the
introduction of the 'Native_context' hook.
