Fix for lsp.c for 16-bit platforms (TI C55x DSP)
Jean-Marc,
Last week I tried the SVN code (build 11700) on the TI C55x DSP, and found that operation was broken again. I traced this to build 11522, committed on 5 June. The problem is in lsp.c, function lsp_to_lpc(). The line (lsp.c line 461 in build 11700):
xin = 1<<(QIMP-1); /* 0.5 in QIMP format */
evaluates to zero. The following change corrects the problem:
xin = SHL32(EXTEND32(1), (QIMP-1)); /* 0.5 in QIMP format */
Regards,
Jim Crichton
