.....you must make sure that all calls are matched with returns. Never jump out of a subroutine without a return and never use a return as an indirect jump." (see paragraph 3.15 in microarchitecture.pdf and examples 3.5a and 3.5b in optimizing_assembly.pdf) Basically this patch replaces call .get_eip0 .get_eip0: pop eax with call .mov_eip_to_eax .get_eip0: and .mov_eip_to_eax: mov eax, [esp] ret -------------- next part -------------- A non-text attachment was scrubbed...

As I wrote earlier, GCC generates slow ia32 code for FLAC__lpc_compute_residual_from_qlp_coefficients_wide() and FLAC__lpc_restore_signal_wide(). So 24-bit encoding/decoding is slower for GCC compile than for MSVS or ICC compile. I took FLAC__lpc_compute_residual_from_qlp_coefficients_asm_ia32 and FLAC__lpc_restore_signal_asm_ia32 asm functions and wrote their _wide versions. -------------- next
