<div style="white-space: nowrap">This optimization speeds up memory accesses by the guest program.</div>
<div style="white-space: nowrap">Enabling it inlines accesses to PageTable::pointers into emitted code.</div>
<div style="white-space: nowrap">Disabling this forces all memory accesses to go through the Memory::Read/Memory::Write functions.</div>
Enable inline page tables
-
<div>This optimization avoids dispatcher lookups by allowing emitted basic blocks to jump directly to other basic blocks if the destination PC is static.</div>
Enable block linking
-
<div>This optimization avoids dispatcher lookups by keeping track potential return addresses of BL instructions. This approximates what happens with a return stack buffer on a real CPU.</div>
Enable return stack buffer
-
<div>Enable a two-tiered dispatch system. A faster dispatcher written in assembly has a small MRU cache of jump destinations is used first. If that fails, dispatch falls back to the slower C++ dispatcher.</div>
Enable fast dispatcher
-
<div>Enables an IR optimization that reduces unnecessary accesses to the CPU context structure.</div>
Enable context elimination
-
<div>Enables IR optimizations that involve constant propagation.</div>
Enable constant propagation
-
<div>Enables miscellaneous IR optimizations.</div>
Enable miscellaneous optimizations
-
<div style="white-space: nowrap">When enabled, a misalignment is only triggered when an access crosses a page boundary.</div>
<div style="white-space: nowrap">When disabled, a misalignment is triggered on all misaligned accesses.</div>
Enable misalignment check reduction
-
<div style="white-space: nowrap">This optimization speeds up memory accesses by the guest program.</div>
<div style="white-space: nowrap">Enabling it causes guest memory reads/writes to be done directly into memory and make use of Host's MMU.</div>
<div style="white-space: nowrap">Disabling this forces all memory accesses to use Software MMU Emulation.</div>
Enable Host MMU Emulation (general memory instructions)
-
<div style="white-space: nowrap">This optimization speeds up exclusive memory accesses by the guest program.</div>
<div style="white-space: nowrap">Enabling it causes guest exclusive memory reads/writes to be done directly into memory and make use of Host's MMU.</div>
<div style="white-space: nowrap">Disabling this forces all exclusive memory accesses to use Software MMU Emulation.</div>
Enable Host MMU Emulation (exclusive memory instructions)
-
<div style="white-space: nowrap">This optimization speeds up exclusive memory accesses by the guest program.</div>
<div style="white-space: nowrap">Enabling it reduces the overhead of fastmem failure of exclusive memory accesses.</div>
Enable recompilation of exclusive memory instructions
-
<div style="white-space: nowrap">This optimization speeds up memory accesses by allowing invalid memory accesses to succeed.</div>
<div style="white-space: nowrap">Enabling it reduces the overhead of all memory accesses and has no impact on programs that don't access invalid memory.</div>
Enable fallbacks for invalid memory accesses
