[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.

You should set them as using/defining your stack register with :
let Defs = [STACKREG], Uses = [STACKREG] in {
__ YOUR INSTRUCTION __
}

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?
