[LLVMdev] Possible LiveIntervals bug
At line 1155 of LiveIntervalAnalysis.cpp (in
LiveIntervals::rewriteInstructionsForSpills), should the condition
be:
if (ImpUse && MI != ReMatDefMI && MI != ReMatOrigDefMI)
instead of:
if (ImpUse && MI != ReMatDefMI)
?
After all, ReMatDefMI is a clone of the original def instruction
(ReMatOrigDefMI). I'm seeing bad things happen, with intervals
getting HUGE_VALF set as their weight because...

Impulses
...o one has gone
down this path before:
Roughtly vorbis currently does:
input wave -> MDCT -> LPC -> LSP -> quant -> ------------------>output
\->delpc->error->quant -^
What do you think of this:
input wav -> DWT -> sum non-impuse factors -> iDWT -> MDCT ... (like above)
\
-> -> sum impulse factors -> iDWT -> LPC -> LSP -> quant
i.e. use a wavelet transform to seperate out impulsey signals and
compress them in the time domain.
The decoder complexity really isn't inc...
