This replaces 13/13 of my v2 series; and now that it has pretty good testsuite coverage and demonstrable performance improvement to nbdinfo, I'm going ahead and pushing this now. We may still want to add further nbd_opt_* commands for other fine-grained tuning of negotiation, but for now, I think things have stabilized on this end, and I can return to polishing .list_exports on the nbdkit

Hi Elena, > (2) Proposal > Define one more Code Model, let's say "LargeNearConst", which will allow to put constants in .text. Isn't that a little heavy-handed? The large model only requires the less efficient access for symbols we can't control, and in fact x86 still uses pc-relative conditional branches within a function so it can't pretend to support a single

...and CodeModel::Small for 32-bit. And the TargetLoweringObjectFile already has CodeModel inside. So the code will look like : const MCSection * TargetLoweringObjectFile::getSectionForConstant(SectionKind Kind) const { if (getCodeModel() == CodeModel::LargeJIT) return TextSection; if (Kind.isReadOnly() && ReadOnlySection != 0) return ReadOnlySection; return DataSection; } - Elena -----Original Message----- From: Tim Northover [mailto:t.p.northover at gmail.com] Sent: Tuesday, June 25, 2013 23:31 To: Demikhovsky, Elena Cc: llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] Contant...

Hi all, I analyzed more and ready (1) to describe the problem and (2) I have a proposal. (1) Problem description: In X86_64 target the Code Model is "Large". It means that address is 64-bit and IP-relative memory operand can't be used in this case. (Because in IP-relative memory operand the displacement is 32-bit). In order to load constant, we use 2 instructions. movabsq
