...FS is not choosing right if write to slog is better or not (thinking if we have a better throughput from disks). But i did not find anything about 100% slog activity (~115MB/s) blocks IO from disks. Two or three seconds of "zero" read or write on disks... Thanks a lot for your time!

Hi, All, Duncan, Rafael, David, Nick. This is regarding pattern matching in InstructionCombine pass. We use 'match' functions many times, but it doesn't do the pattern matching effectively. e.x. Lets take pattern : (A ^ B) | ((B ^ C) ^ A) -> (A ^ B) | C (B ^ A) | ((B ^ C) ^ A) -> (A ^ B) | C Both the patterns above are same, since ^ is commutative in Op0. But,

Hello all, Every night i receive the messages: rsync: connection unexpectedly closed (14801530 bytes received so far) [generator] rsync error: error in rsync protocol data stream (code 12) at io.c(453) [generator=2.6.9] but the synchronization process seems to be right... so the question: What can be the cause of that messages?

So, my question is: Do I have to manually convert amplitude samples to frequency samples or is it enough to send amplitude parameters to speex_echo.h functions that this functions automatically convert it and do the AEC?

(iirc, it wants you to use eax = LEA > rsi, rdi) I am turning 32-bit add into 32-bit LEA on x86-64 but that's perfectly legal. Both leal (%esi,%edi), %eax leal (%rsi,%rdi), %eax are legal assembly. It's just the former requires a 67H prefix due to the 32-bit address size. This does point to a performance problem in the 3 address conversion code (which I will fix), but it should not cause the assembler to complain. Evan...
