[linux-audio-dev] [i686] xmm regs + gcc inline assembly

can anybody help out with gcc inline assembly syntax applied to sse registers/memory locations? for a simplified example, i'm using float t[4]; ... asm ("movaps %%xmm1, %0" : : "m" (t[0])); to move 4 packed floats from xmm1 into 't'. my suspicion is that gcc concludes from the expression that only t[0] has changed, so if i'm unlucky the optimizer ignores the contents of t[1:]. it does the right thing right now, but i want to go sure this is reliable under all conditions. one possible solution seems to use struct/union instead of float[4] (iirc that's the way fftw-3 does it) but i'm aesthetically inclined towards the more direct float[] notation. i've dug deep into the gcc info files, but they rarely touch the issue (and are darn tedious to read). using gcc-3.x builtins is not an option. so, can anybody help me code this properly? thanks, tim
