The ARM926EJ-S Technical Reference Manual states: > You can only access CP15 registers with MRC and MCR instructions in a > privileged mode. CDP, LDC, STC, MCRR, and MRRC instructions, and unprivileged > MRC or MCR instructions to CP15 cause the Undefined instruction exception to > be taken. Furthermore, `MCR p15, 0, <Rd>, c7, c10, 5` (later called Data Memory Barrier) is not specified for the ARM926. Thus, SDL should not use these cache instructions on ARMv5.
Simple DirectMedia Layer (SDL) Version 3.0
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
