The 's' suffix on the cmp instruction is deprecated and superfluous since the cmp instruction always sets conditional flags.

..., while shifting a small positive number down will result in 0. Don't know if it is an issue that the fixed point arm code is not bit exact. I have included a patch against the 1.1.11.1 that will make the filter_mem2 bit exact with the C. -Fritz -------------- next part -------------- --- filters_arm4.h 2005-11-16 06:08:28.000000000 -0500 +++ filters_arm4_new.h 2005-12-06 11:06:51.012221200 -0500 @@ -240,9 +240,11 @@ "\tmov %8, %8, lsr #15\n" "\tadd %10, %8, %9, lsl #17\n" "\tldrsh %6, [%2], #2\n" - "\tsmull %8,...

Sorry, been busy with maintenance on Valin 2.0 and 3.0 :-) Just applied your fix to the assembly. Can you confirm it works

Hi everyone, I'm planning on releasing Speex 1.2beta2 in the next few days. I'd appreciate if everyone could try and test the current svn to make sure no bug crept in for your favourite plarform/application. Cheers, Jean-Marc

Here is how I'm doing this for filters_arm4.S - see arm-asm-configure.diff and arm-asm-configure2.diff patches. These two patches doing the same, but differ in the way OVERRIDE_* macros are defined. In first case they are defined right in filters.c, in second case they are defined in src/Make?file.am. And I'm attaching other fix for con...
