09985655a2 Fix host-sdl/doom audio. Have app ask via syscall if audio can be rendered before sending, else any mismatch in rates will cause queue over/underflow in host-sdl. 2025-12-15 10:48:10 +00:00

9bda566997 Move internal static garbage into vmst. 
Potentially, this could have ended up being non-zero when used by concurrent threads.

5dc9acdf3d When a trap occurs in mini-rv32ima, always pass to the host rather than allowing running code to handle it. This would be important for a real OS, but the aim of uvm32 is embeddable logic - not full emulation. 
As all traps are caught by host, begin testing mini-rv32ima internals by checking PC oob and PC alignment.

apps/maze: fix possible stack overflow

cdfae7d453 apps/maze: fix possible stack overflow 
The original code this app is inspired from uses rand(), which returns
a number >= 0.
mulberry32() on the other hand can return a negative number, in which
case will overflow the accesses in the dirs array. Fix that by forcing
the result to be unsigned.
