Lioncash e95076f321 SignalDelegator: Migrate from std::unexpected() to std::terminate() 
std::unexpected() was deprecated in C++11 and removed from the standard
in C++17. The default unexpected_handler would call std::terminate
anyway, and given we don't explicitly set a termination handler (as far
as I can tell), this retains identical behavior.

Lioncash e2a16c53b6 SignalDelegator: std::move std::function instances 
std::function is allowed to allocate if the size of captures exceeds its
internal storage buffer. It's unlikely this is regularly going to be the
case, but we can allow for avoiding it where necessary.

Lioncash ee89b7a794 SignalDelegator: Leverage std::array 
Allows for better detection of out of bounds accesses, as library
implementations generally allow conditional enabling of bounds checks
through preprocessor defines.

Lioncash a2b8fedba5 Utils: Add header for bit-related utilities

Lioncash 341b811642 Utils: Add CompilerDefs.h for compiler-specifics 
Puts a layer of separation around compiler specifics (and also makes
them nicer to write).

Lioncash aa2c18d8cc CodeLoader: Add type aliases for mapper and unmapper functions 
Centralizes the long types in one place for less reading.

Ryan Houdek 2e8aacffe6 Fixes compat_ptr to return reference instead of copy 
The expectation was that a reference would be returned rather than a copy.
Oops

Ryan Houdek 2101914c9d Adds drm headers to an external repository 
It's highly likely that the host system won't have these headers installed.
Carry them in an external repository to ensure they are available.

Fixes #1047

Lioncash 525d50f07e config: Pass strings by const reference where applicable 
In a few cases, the strings aren't ever directly modified, so they can
be passed by reference to eliminate a few trivial copies.
 2021-06-04 12:46:34 -04:00
Lioncash 5cec8ddca0 config: Move input strings in Loader constructors 
Eliminates a copy, minor, but basically a "free" change.
 2021-06-04 12:40:38 -04:00
Lioncash 39b2be15ab config: Make use of heterogenous map lookup 
Same behavior, but allows lookups without constructing a std::string
(in most cases find() inputs use const char*, so this gets rid of some
string churn).

Ryan Houdek 822a08f271 FEXConfig: Allow lower GL versions 
Automatically fall back through older GL versions

This allows us to freely support GL 3.0, 2.1 and ES 2.0.
Should fix an issue where Pi devices don't support GL 3.0 in all configs

External imgui had to be updated to fix an issue with ES 2.0

Fixes #1036

Ryan Houdek dfb15aaeb9 ppoll fixes 
glibc implementation makes a copy of the timeout and the kernel is expected to update it
Can't use the glibc implementation because of this.

Ryan Houdek 565f0e6af3 Handle FD flag remapping correctly 
FD flag remapping was broken. It would remap one flag on to another and then the next check would remap it back.

Instead keep a mask of the flags to be remapped then remap them all at the end.
Also goes through the ops and fixes a few cases where it was remapping wrong flags.

Ryan Houdek b03554bb7d Sigaction fixes 
Check for invalid sigsetsize

Since we are using SignalDelegator we don't use errno, so just return Result and check for Result == 0

Ryan Houdek 7b8cb5107a Emulate MAP_32BIT in mmap 
If we are on AArch64 then MAP_32BIT doesn't exist.
Emulate it by setting the address as a hint to the kernel so it scans bottom up
