[LLVMdev] How to prevent Dead-Code-Elimination pass removing pseudo-instructions ADJCALLSTACK(DOWN | UP)?
Hi, LLVMer. I use pseudo-instructions ADJCALLSTACK(DOWN | UP) to adjust call stacks, and it works well with "-O0" option. However, ADJCALLSTACK(DOWN | UP) are removed during codegen DCE pass under "-O2". What have I ignored? Thanks. -- 杨勇勇 (Yang Yong-Yong) -------------- next part -------------- An HTML attachment was scrubbed... URL:

You should set them as using/defining your stack register with : let Defs = [STACKREG], Uses = [STACKREG] in { __ YOUR INSTRUCTION __ } Marcello On 04/09/13 07:56, 杨勇勇 wrote: > I use pseudo-instructions ADJCALLSTACK(DOWN | UP) to adjust call > stacks, and it works well with "-O0" option.

Maximum zfs send/receive throughput
It seems we are hitting a boundary with zfs send/receive over a network link (10Gb/s). We can see peak values of up to 150MB/s, but on average about 40-50MB/s are replicated. This is far away from the bandwidth that a 10Gb link can offer. Is it possible, that ZFS is giving replication a too low priority/throttling it too much?
