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.
This commit does three things that are bounded to each other
1) Moves configs from ConfigValues.inl to Config.json
2) Uses the json to generate a man file with the options inside of it
3) Generates the code required for FEXLoader to automatically parse defined options
Moving the configuration options to a parseable format was required to generate the man pages.
Can't really include an inl file in the man page
Man page gets generated and installed through the regular cmake install process
`man FEX` to get the man page
With this change, FEXLoader's argument parsing now will automatically be generated from the json.
This way whatever is in the json file matches what is in the man page, in the json, AND what is returned in FEXLoader --help.
It will stay in sync now.
FEXConfig is the only application that stays out of sync for now as it requires some more thought to plan out.
A minor improvement that this brings as well is that every boolean option that has a long argument also gains the inversion of that property.
aka, `--gdb` also gains `--no-gdb` The use case for this is minor but boolean arguments should always allow negated variants.
This was a missing feature that I had skipped previously.
Before this commit, each layer would overwrite all previous environment variables if they had anything defined.
After this commit, the layers will now merge in priority order.
Meaning if a higher priority layer has the same environment variable defined, it will overwrite that specific variable
Ending up with a superset of all the layer's environment variables now.
Useful for debugging but we need to be silent by default now.
Without this anything that checks stdout output of applications from bash would fail
Steam with lspci, lsusb, uname, etc
This was previously just some default values that I put in as placeholder
Now that we actually have defaults configured somewhere, use those.
Fixed#874
This has the expected behaviour that the configuration option will be available and not default initialized.
To enforce this fact, it will assert if it tries to get a value that doesn't exist yet.
Passes the result back up to the frontend as well which allows us to early exit correctly.
Also ensures that we return ENOEXEC on these error cases so if someone is waiting on a return value, they don't just get zero
Fixes#757
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
