Description Ryan C. Gordon 2006-08-03 16:34:37 UTC 
SDL_Swap32() isn't convenient for floating point values. Might be nice to have an SDL_SwapFloatBE() and SDL_SwapFloatLE() API.

Sam, can you look at svn revision #2707 and make sure this isn't completely dumb?

Looks good, as long as the optimizer doesn't do anything stupid like leave the value in the FPU. :)
Comment 3 Ryan C. Gordon 2006-08-26 17:10:24 UTC 
I think it probably disables all aliasing optimizations when it sees the union. If the new symbol names are acceptable, we'll leave this bug as resolved.
