The flags calculation is fairly intensive and we were doing it for every core.
Do it once then duplicate it per core instead
Improves generation time quite significantly. A couple of milliseconds converted to half a millisecond
Slight improvement to startup time
C++ no-op functions can't optimize out the predicate arguments in all cases.
This was causing a problem where zero cost assertions weren't actually zero cost.
The only way to resolve this is to actually use macros sadly enough.
This will give a fairly hefty performance uplift with anything operating on IR.
FEX doesn't support seccomp in userspace and allowing these through causes chromium secure sandbox to break.
Disabling these with EINVAL allows FEX to behave as if seccomp isn't enabled in the kernel config
Necessary to get the Civ6 launcher further
Notably this allows applications to work that don't require the namespace but check up front if they are able to clone with it.
Civ 6's launcher checks this as an example
We are only using this for syscalls getcap and setcap.
These are only passthrough pointers and don't need to be handled from a library.
Noticed this while writing user documentation
This will be necessary for struct verification in the next commit
rusage needed to be updated to match the real rusage. Has unions with two named types
This wasn't following the correct format and it never actually had a working FEX_VERSION define.
Now it pulls in the GIT_DESCRIBE_STRING and brings in the correct date + time format
The vast majoirty of syscalls don't need anything in thread or frame.
So lets save an indirection for all those syscalls.
Most of the syscalls which do need Thread (or CTX via
Thread are in Thread.cpp or Memory.cpp
These have all been modifiy to fetch Thread from Frame
Configuration mapping was duplicated between three different tables.
Additionally default configuration values were strewn about. Making it confusing as to what the default value would end up being
Adds a new ConfigValues.inl header that defines a few things right next to each other.
Defines the enum name as usual.
Defines the JSON config option name.
Defines the Environment config option name
Defines the default value that the configuration should be
