rpmalloc is currently very aggressively configured which causes
significant reductions in resident memory over jemalloc.
In Bayonetta's title screen it went from 963MB down to 834MB resident.
This allows the context and parent thread objects to be created earlier,
allowing the VDSO and ELFCodeLoader mapping functions to have a thread
object for tracking memory mappings through the regular guest routines.
This means that we no longer need to do any form of deferred handling
for code caching as all the state is ready early in the initialization
process.
A little bit of care needed to be taken to ensure we still close the
ELFCodeLoader's FDs later and that VDSO unmapping happens before tearing
down the parent thread, but overall this is mostly just passing the
InternalThreadState object around as normal.
I couldn't find any functional regression from this change alongside
code caching, but it would be good for @neobrain to double check this.
I may have gotten carried away.
- I missed some stuff for end parenthesis because I accidentally
searched within project files instead of the entire directory (so some
thunk/test/windows stuff was missed), cleaned those up.
- `INTERFACE`, `PUBLIC`, `PRIVATE`, `RUNTIME`, `LIBRARY` should be on
the same line as the target name. (I should really invest in making a
style guide...)
- Some short statements were unnecessarily split across multiple
lines--cleaned those up
- Made a common `LinkerGC` module that applies gc-sections etc. to a
target in Release mode
- Usually for functions you want to have something on the first line,
e.g. `FILES`/`DIRECTORY` for install, or the target/a positional
argument, etc etc. Not always though, notably for some custom_command
calls
TODO:
- What's with the `list(APPEND LIBS...)` stuff? It's used really
inconsistently, sometimes not at all, sometimes it looks like there're
duplicates? A more thorough cleanup is in order there.
