Just use the syscall directly rather than call through the glibc
interface.
The getpriority syscall biases the return value so it never returns a
negative, while the glibc interface returns [-20,19), so you need to do
some errno juggling for the -1 return.
Just use the syscall directly instead
Fixes some game complaining heavily when getpriority results were wrong
Previously we never checked for SS_DISABLE.
We were also only ever checking for ss_sp being a valid memory range
when we should have been checking for the absense of SS_DISABLE.
Fixes#326
Instead of having this file mostly just copy and pasted, it'll now be
generated.
We end up losing a lot of supported flags with this change, which is for
the best since we wouldn't have actually supported those things.
Instead of saying we support the world, actually go through each
individual flag and say that we support the correct things.
Puts FEX plus the git hash in to the model name for now.
Once we have a tagged release in the future we can change this to have
its version tag inside of it.
If the host CPU supports RCPC instructions then it'll use those
instruction of atomics for LoadMemTSO ops.
This pushed my worst case FTL test from 16FPS to 17FPS .
There is another extension to RCPC to add short immediate offset support
which the c630 doesn't support any way. For future optimization on
hardware we can use that.
We have hit issues where the non-clean folder would end up leaving
artifacts which allowed tests to pass.
Remove the build folder on each run to clean up
This will install a binfmt_misc target for x86_64 targets that allows
FEXLoader to be the interpreter.
Everything else is already set up to allow this to work, just time to
hook it up.
Ensures the top of the loop is 16byte aligned to give Cortex's
prefetcher the best chance of loading the code.
If the address size is a power of two (We always do 64GB or 32GB VM atm)
then do the address size masking in one instruction instead of loading a
64bit constant first
Move some accessed constants to a literal pool at the end of the ASM
dispatcher.
Was accidently setting the buffer size then unmapping at that new size.
Make sure to unmap then resize.
Also cleans up which buffer is actually being touched here, only the
initial buffer ever changes here.
This requires implementing custom ASM dispatchers for the interpreter
side of things so it works correctly.
Allows all of our CPU backends to safely support signaling.
This is a bit of a nightmare change and requires rethinking logic about
debugging in some instances.
Mutlblock pass that eliminates flag stores that are never read.
This is a sibling to RCLSE and will likely be absorbed by it when we add MB support there.
