Only one code change: for some reason, GCC chokes on the cr3 functions
as macros (throwing errors about invalid registers.) The BSDs have them
as inline functions instead, so they are converted to that here.
Tested and working. There seems to be about a 10% decrease in CPU time
on some compilation benchmarks that I briefly tried.

Only on non-GCC2 for now, as GCC2 does not have -fvisibility.
An opt-out is left as a possibility, and is unfortunately necessary
for libshared and libicon, as these two are used even in WebKit instead
of linking to the .a. However, libcolumnlistview, libagg, and a whole
bunch of others are now no longer exported, so this is already a major
improvement on what symbols we were leaking.
This may provide performance differences for consumers of these APIs,
as GCC and the linker are now free to merge and directly use functions
that previously could have been semantically interposed. AGG usage in
app_server, especially, may benefit.
We can also now remove the addition from libnetservices, so do that.
That is, it will now pull in NEEDLIBS and LINKLIBS set by LinkAgainst
from static libraries also built by Jam. This allows specifying what
libraries other static libraries need only once (in most cases;
occasionally things are not evaluated in a sane order and then
this does not quite work.)
Use this for libnetservices.a, which needs libshared.a, so that
dependencies on it do not have to be declared within most in-tree
consumers of libnetservices (e.g. Package Kit, http_streamer, etc.)
Also remove the MINGW support, as it was far too incomplete.
This *should* work under case-sensitive NTFS, but instead,
it seems #14963 occurs. So perhaps there is a GCC bug
related to case-sensitive vs. case-insensitivity after all.
In some LTO-related experiments, it came out empty due to GCC
not generating actual assembly but rather intermediate code,
resulting in various later targets failing with quite literally
thousands of errors.
This doesn't fully work yet (the FS code in libroot_build
needs to be adapted, as some of the symlink-related calls
are not available on MinGW), but it gets much further than
the "Cygwin" target did.
These have been broken for a long time. Some Cygwin changes that
are relevant on MinGW are kept here, but users on Windows who
want to build Haiku should probably use WSL at this point.
However, now that we are using relative paths and don't need
to worry about drive path kludges, it's actually possible to
get some host tools built on MinGW. Changes for that coming.
"cpp" is the system C preprocessor, not the one from our cross-compiler,
and in the case of my system which does not have GCC installed at all,
it doesn't even exist.
With this, Clang-ARM builds successfully create a "haiku-arm.mmc".
I couldn't get it to output, even after blessing it with "rune",
but that may just be my fault...
It seems that at on some platforms at least, Clang uses @define instead
of #define, but with functionally identical syntax, so use sed to
process it as such.
* The if-case was appending to gccBaseFlags after the rest of the file
was done using it, so it was ineffective. Now we set it with the rest
of the baseFlags.
* We already pass no-integrated-as in configure, no need to do it in
MainBuildRules.
* B_USE_BUILTIN_ATOMIC_FUNCTIONS isn't used anymore, so get rid of it.
Previously we just used the system libroot, which of course meant
that when libroot's ABI changed, the build broke. Now we use the full
libroot_build that we do on non-Haiku platforms. The logic for "BeOS-compatible
but not Haiku" does not really apply anymore, so it has been gutted where
appropriate (and libhaikucompat has been decoupled from the build.)
The only caveat here is the change to Errors.h -- we really should be using
the system's one where I included the one from the tree, but for whatever
reason, GCC2 refused to handle the #include_next properly.
Fixes the build breakage of Haiku-on-Haiku by my prior commits (sorry).
This depends on quite a nasty hack to generate those, namely using
inline assembly to generate a file with things that are not actually
assembly, which Clang therefore filters out.
This makes it possible to %include local files. nasm doesn't allow this
otherwise (include paths are assumed relative to the working directory).
Fixes build of ape_reader.
Recent linux behaviour (and also copied by BSD) is to preprocess
DTS files with the C preprpocessor to enable sharing constants between
driver implementation and DTS content for more readability.
* Instead of faking libstdc++.so from libstdc++.a, use libstdc++.so
from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku
source tree as part of the Haiku build .
* Put gcc_syslibs package onto the image, when needed.
provided in the gcc_syslibs_devel build feature for building Haiku.
* Simplify declaration of c++ and gcc headers for the legacy compiler -
in the end we always use the ones living by our source tree anyway.
* Fix a couple of missing local declarations for jam variables, which
were necessary to avoid a build problem with strace. There are
probably more bugs like these hiding in our build system files, but
I'm saving the fix for those to the next commit.
* Add new gcc packages to the HaikuPorts (x86*-)repositories.
* The main build rules now cause their targets to depend on the
platform such that global per-platform intializations can be
set up by making the platform pseudo target depend on the
target returned by the initialization rule.
The introduction of secondary arch support for kernel files disabled
-Werror for all kernel files, since the -Werror flags were moved from
{CC,C++}FLAGS to TARGET_WARNING_{CC,C++}FLAGS_<arch>, which, however,
was overwritten by the SetupKernel rule. This commit introduces new
global variables {HAIKU,HOST,TARGET}_WERROR_FLAGS[_<arch>], which
contain the additional -Werror flags to be applied for the architecture.
The config variable WARNINGS can be set to "treatAsErrors" to cause
-Werror and {HOST,TARGET}_WERROR_FLAGS[_<arch>] to be appended to the
compilation flags.
Fixes#10280.
Both for the rPI and the Verdex target we now have FDTs. The verdex
DTS is homebrew, the pxa DTSIs come from Linux and should be kept
in sync.
The rPI DTS and Broadcom DTSI come from FreeBSD HEAD, and should
ofcourse also be kept in sync.
One global new Jam rule has been introduced for handling DTS
compilation, aptly named CompileDTS....
More coming!
* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
handlers have been moved to teams. Fixes#5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
of the real-time signal range. Closes#1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes#6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
[set]itimer(). Closes#5682.
* Implemented support for thread cancellation. Closes#5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes#7554.
* Lots over smaller more or less related changes.

* when adding a library to the image, its optional minor abi version is taken care of, too (i. e. a
corresponding link is created).

Re-running configure or adding the variable manually to
generated/build/BuildConfig is required.

* add cygwin specific options.
* Cygwin cannot handle -fPIC option and throws warnings, thus we only use it on non windows platforms for the host tools.
* Windows uses PATH instead of LD_LIBRARY_PATH, so before calling a host tool this environment variable needs to be expanded... Brilliant...
* Using jam on Windows is kind of complicated, as the cygwin included gcc creates executables with a .exe extension. When jam parses dependencies for being up to date it ignores this extension again and tries to rebuild the executables again and again. This hack removes the extension after successful linking. Though jam has a SUFEXE variable for cygwin builds, we cannot use this one directly as crosscompiled targets do not have an extension, it is complicated to use the same jam for both platforms. A more clean attempt would be to check for the extension on each host target depending on the platform. This should be fixed later on.
* Btw. Say hello to Haiku compiling successfully on Windows :) with one patch to be discussed for jam...

-nostdlib disables that for executables although it should be enabled by
default.
