Don't know the *.opt stuff enough if there is a way even for the -mcpu= etc. options to cancel all previous occurences with different strings from matching, if not, perhaps at least the list in rs6000.h should be sorted such that at least in most cases assembler flags that are superset of others are before flags for the subsets. typedef struct { int channels; void *codec_setup; } vorbis_info; typedef struct vorbis_dsp_state { vorbis_info *vi; float **pcm; long W; void *backend_state; } vorbis_dsp_state; typedef struct vorbis_block { float **pcm; } vorbis_block; typedef struct private_state { int window[2]; } private_state; typedef struct highlevel_byblocktype { long blocksizes[2]; int halfrate_flag; } codec_setup_info; extern float *_vorbis_window_get (int n); void vorbis_synthesis_blockin (vorbis_dsp_state * v, vorbis_block * vb) { vorbis_info *vi = v->vi; codec_setup_info *ci = vi->codec_setup; private_state *b = v->backend_state; int hs = ci->halfrate_flag; int i, j; int n = ci->blocksizes[v->W] >> (hs + 1); int n0 = ci->blocksizes[0] >> (hs + 1); int n1 = ci->blocksizes[1] >> (hs + 1); int thisCenter = 0, prevCenter = 0; for (j = 0; j < vi->channels; j++) { float *w = _vorbis_window_get (b->window[1] - hs); float *pcm = v->pcm[j] + prevCenter; float *p = vb->pcm[j]; for (i = 0; i < n1; i++) pcm[i] = pcm[i] * w[n1 - i - 1] + p[i] * w[i]; float *w2 = _vorbis_window_get (b->window[0] - hs); float *pcm2 = v->pcm[j] + prevCenter; float *p2 = vb->pcm[j] + n1 / 2 - n0 / 2; for (i = 0; i < n0; i++) pcm2[i] = pcm2[i] * w2[n0 - i - 1] + p2[i] * w2[i]; for (; i < n1 / 2 + n0 / 2; i++) pcm2[i] = p2[i]; float *pcm3 = v->pcm[j] + thisCenter; float *p3 = vb->pcm[j] + n; for (i = 0; i < n; i++) pcm3[i] = p3[i]; } } ^ permalink raw reply [flat|nested] 8+ messages in thread
