Nov 10, 2009 issue 6 (iPhone Release run Problem) reported by zhangkaich - What steps will reproduce the problem? 1. iPhone OS 3.0 Release App . Application run error. 2. I found R0 register may be overwrite. I read // NOTE: Lots of VFP macros overwrite register r0, therefore you have to make sure // to include "r0" in the list of registers used, as in above example. how can i avoid this problem?

Thanks, --th May 02, 2009 issue 2 (optimisation suggestion) commented on by alanic - My reading on the ARM Architecture Reference Manual ( http://www.arm.com/miscPDFs/14128.pdf ), pages C2- 26 and C2-10 indicate that the cumulative exception bits are for reading to see if there was an exception or not since you last cleared them. My understanding is that clearing them is not required to get to runfast mode, you just need to clear the enable bits, which are already cleared by default. So, solely on the material I read, I agree with comment 2 by Julien.

Apr 07, 2009 issue 3 (fast_sin() is super slow) commented on by julien.cayzac - What difference is there between a scalar and a vector whose size is 1?

Apr 07, 2009 issue 3 (fast_sin() is super slow) commented on by damien.morton - My understanding is that that SIMD_UNITS_PER_WORD message is a warning, and results in a vector size of 1 being chosen. I have seen performance improvements turning it on, but on larger bodies of code, and I have spoken with others who swear by it. I cant say I have examined the asm output closely enough to detect what the difference is.

Apr 06, 2009 issue 3 (fast_sin() is super slow) commented on by damien.morton - The actual fast_sin() routine was written to test the vector implementation, vsinf against. No attempt at optimisation was made (probably should have called it something other than fast_sin). Note that fast_sin() also performs range reduction, which your code omits. Looks to me like abs() is resulting in fabss instructions, and that round() is calling out into library code, which is probably the worst performance offender. You might also want to try -ftree-vectorize in your CFLAGS. The actual fast_sin() routine was written to test the vector implementation, vsinf against.

I'm reading up on it now; I hope you do get a chance to package this up library-style. Thanks!
