similar to: Real hardware for opus

So an iPod made in the last 4 years has not even a dsp that's used for help in low-power playback of mp3? What are my best options for a portable player I can put opus on and have 10 hours of opus playback?

The vast majority of audio players do *not* have special hardware for MP3 and Vorbis. Decoding audio is so cheap that there's no reason to bother with the trouble of having a dedicated hardware for it.

No worries, thanks for the update.

Is -fsplit-stack option used anywhere? My wild guess is that with ld.bfd, the thinLTO link for the DSO does not bring in morestack.o from libgcc.a, but the hidden symbol is defined in lldb binary.

I use a SanDisk Clip+ running Rockbox; these are available for around ?25 refurbished. They get about 14h playing time on their internal batteries. The newer SanDisk Clip Zip is also supported by Rockbox and is actually a bit

I tried building llvm, clang, lld, lldb from the 3.9 svn release branch with LTO, and some of the results were unexpected. I first tried to rebuild llvm with llvm-3.9, which has ThinLTO, by providing -DLLVM_ENABLE_LTO=Thin, but that failed very quickly, so I fell back to building with -DLLVM_ENABLE_LTO=On and using the system CC/CXX (gcc 6.1). The resulting installed build is many times bigger
