...w to make this work would _really_ make my week. This has been hard to debug, as I don't get any errors, just an empty output .o file... I was thinking it may be because of section issues, so I did add some initial sections, hoping that might help: Str->InitSections(false); MCSection *textsect = Ctx.getELFSection(".text", ELF::SHT_PROGBITS, ELF::SHF_EXECINSTR | ELF::SHF_ALLOC); Str->SwitchSection(textsect); This did not seem to help at all. I'm running out of ideas. Anyone know how to use an MCStreamer object directly to make and object file? Thanks so much for y...

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

...eModel::LargeJIT for x64 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 Subj...

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
