Nintendo does this as of latest firmware.
It's desirable because it removes the only usage of util::SNPrintf() from os library,
which means programs which don't otherwise use SNPrintf do not need to link it into .text.
This saves ~0xD40 of .text as of time-of-commit when successfully unlinking, and e.g.
reduces our sm (and other modules) memory size by a page.
* ams: update to build with gcc10/c++20
* remove mno-outline-atomics
* ams: take care of most TODO C++20s
* fusee/sept: update for gcc10
* whoosh, your code now uses pre-compiled headers
* make: dependency fixes
This was needed to make stratosphere buildable with debugging on.
os:: assertions rely on GetCurrentThread() working, and this requires
the global os resource manager to be constructed. However, __appInit executes
before global constructors. We now require that hos::InitializeForStratosphere()
be called before anything else is done. This initializes the os resource manager,
sets the hos version for libnx, and may do more things in the future.
TODO: Consider replacing __appInit/__appExit with ams:: namespace functions in general,
and wrap them so that we guarantee hos::InitializeForStratosphere is called first, and
generally ensure a consistent stratosphere environment.
This was tested using `https://github.com/node-dot-cpp/alloc-test` plus a few other by-hand tests.
It seems to work for the case we care about (sysmodules without thread cache-ing).
External users are advised to build with assertions on and contact SciresM if you find issues.
This is a lot of code to have gotten right in one go, and it was written mostly after midnight while sick, so there are probably un-noticed issues.
