...SSE optimizations lpc_restore_signal_16_intrin_sse2 and lpc_restore_signal_wide_intrin_sse41. Looks like a define check is missing since the implementation of these functions is only included when not building for integer. I had to exclude them at libFLAC/stream_decoder.c:408 by adding a check for !FLAC__INTEGER_ONLY_LIBRARY. //Joakim ---------------------------------------------------------------------- Intel Sweden AB Registered Office: Isafjordsgatan 30B, 164 40 Kista, Stockholm, Sweden Registration Number: 556189-6027 This e-mail and any attachments may contain confidential material for the sole use of the intend...

Hi, I was wondering how much worse FLAC performance would be if it was compiled integer-only, but while trying to do so (by adding #define FLAC__INTEGER_ONLY_LIBRARY 1 to config.h, just on x86_64-linux) I got this error > ./include/private/bitmath.h:134:5: error: operator '&&' has no left > operand bitmath.h:134 is the following line > #if && defined(__GNUC__) && (__GNUC__ >= 4 || (__GNUC__ == 3 && >...
