Fernando Sahmkow 2fa1c1d13c A32: Allow cleaning up exclusive state from the interface. 
This function is normally required for emulating certain OS mechanisms.

MerryMage 2796a85096 interface/a32: Remove descriptor argument from Disassemble 2020-06-12 15:27:42 +01:00
MerryMage 94d0d33e02 Fix single stepping for certain instructions 
Several issues:
1. Several terminal instructions did not stop at the end of a single-step block
2. x64 backend for the A32 frontend sometimes polluted upper_location_descriptor with the single-stepping flag

We also introduce the enable_optimizations parameter to the A32 frontend.

MerryMage 2f2a859615 a32_jitstate: Consolidate upper bits of location descriptor into upper_location_descriptor 
Also solves a performance regression initially introduced by b6e8297e369f2dc4758bafe944e51efb8d1a2552,
primarily due to excessively mismatched load/store sizes causing less than optimal load-to-store forwarding.

Merry f252a62c1b Merge pull request #502 from lioncash/header 
General: Remove unnecessary includes
 2020-04-22 21:04:22 +01:00
Lioncash 349d4b577a General: Remove unnecessary includes 
Removes unnecessary header dependencies that have accumulated over time
as changes have been made. Lessens the amount of files that need to be
rebuilt when the headers change.
 2020-04-22 21:04:22 +01:00
Lioncash ccf923305c a32_interface: Remove duplicated documentation comments 
These already exist in the header, so these ones can be removed.
 2020-04-22 21:04:22 +01:00
Lioncash 6187de7ca7 a32_interface: std::move UserConfig where applicable 
UserConfig instances contain up to 16 std::shared_ptr<Coprocessor>
instances. We can std::move here to avoid performing 16 redundant atomic
reference increment and decrement operations.

Mostly inconsequential on x64, but we may as well signify intent.

Lioncash b13b6610b5 a32_interface: Default destructor in the cpp file 
Makes it more consistent with code throughout the codebase.

MerryMage 6e2cd35e4f a32_jitstate: Optimize runtime location descriptor calculation 
Calculation is now one unaligned 64-bit load.

MerryMage 0de3993373 a32_jitstate: Remove fpsr_idc 
We do not really have accurate FPSR state in any case.

Lioncash 2e180a7f14 backend/x64/a32_interface: Mark Context move constructor and move assignment as noexcept 
Provides a more "correct" move constructor/assignment operator, since
these relevant functions shouldn't throw exceptions.

Has the benefit of playing nicely with std::move_if_noexcept and other
noexcept library facilities.
