Ref #3848
This commit uses CUSTOM_HOST_CC/CUSTOM_HOST_CXX instead of hardcoded
commands and introduces HOST_DEV_PREFIX.
Original patch by Roman Iten and Pirmin Duss.
Issue #3466
The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
'SANITIZE_UNDEFINED = yes' in 'target.mk' adds the '-fsanitize=undefined'
compiler flag and links the program with libubsan and libsanitizer_common.
Issue #3072
This patch enables the warnings -Wextra, -Weffc++, and -Werror for
compiling Genode components. It thereby helps us to detect bugs like
uninitialized member variables or missing virtual destructors at compile
time. The warning level is defined via the new 'CC_CXX_WARN_STRICT'
variable. For targets that compile 3rd-party code where this warning
level is not applicable, the variable may be explictly set to an empty
value in the corresponding build-description file.
Issue #465
This is helpful for disabling messages in etc/tools.conf by
setting it to e.g.
MSG_LINK = @true ""
This results in much shorter and less cluttered logs in automatic
builds.
The <build-dir>/bin/ directory used to contain symbolic links to the
unstripped build results. However, since the upcoming depot tool
extracts the content of binary archives from bin/, the resulting
archives would contain overly large unstripped binaries, which is
undesired. On the other hand, always stripping the build results is not
a good option either because we rely of symbol information during
debugging.
This patch changes the installation of build results such that a new
'debug/' directory is populated besides the existing 'bin/' directory.
The debug directory contains symbolic links to the unstripped build
results whereas the bin directory contains stripped binaries that are
palatable for packaging (depot tool) and for assembling boot images (run
tool).
This patch make the ABI mechanism available to shared libraries other
than Genode's dynamic linker. It thereby allows us to introduce
intermediate ABIs at the granularity of shared libraries. This is useful
for slow-moving ABIs such as the libc's interface but it will also
become handy for the package management.
To implement the feature, the build system had to be streamlined a bit.
In particular, archive dependencies and shared-lib dependencies are now
handled separately, and the global list of 'SHARED_LIBS' is no more.
Now, the variable with the same name holds the per-target list of shared
libraries used by the target.
The linker scripts are known to reside in BASE_DIR. By using them
directly from this location instead of searching them in the
REPOSITORIES, we don't need to specify the repos/base as a repository in
order to link.
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
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
We set 'ld -z max-page-size' to 4KiB to prevent the linker from aligning
the text segment to any built-in default (e.g., 4MiB on x86_64 or 64KiB
on ARM). Otherwise, the padding bytes are wasted at the beginning of the
final binary.
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.
