Hi, Thanks for pointing direction. As far, as I understand by reversing, logic, that I want to overwrite is digged into: lib/MC/MCSectionELF.cpp MCSectionELF::PrintSwitchToSection if (ShouldOmitSectionDirective(SectionName, MAI)) { OS << '\t' << getSectionName() << '\n'; return; } // otherwise print ".section" directive and then section name So I need to overwrite ShouldOmitSectionDirective behavior. But this meth...

This is a feature (or bug) of MCSectionELF::PrintSwitchToSection. For ELF target this function tries to escape string if it founds 'suspicious' character, see implementation in MCSectionELF.cpp: StringRef name = getSectionName(); if (name.find_first_not_of("0123456789_." "abcdefghijklmnopqrstuvwxyz&quot...

...changes look to be fairly independent of yours, my change was to deal with COMDAT's. I had dealt with the characteristics flags in the object writer, but I like this. If you don't mind I would like to merge my changes into this patch and submit it. I was just pondering how to deal with the PrintSwitchToSection function without needing the IsDirective flag. I prefer to merge in small independent patches as they are built. Please review Peter's patch (since you know COFF :). I'll take a look tomorrow and apply it if you think it is forward progress, and if there aren't other issues. Than...

Hi, In the document: http://llvm.org/docs/WritingAnLLVMBackend.html described example like: SparcTargetAsmInfo::SparcTargetAsmInfo(const SparcTargetMachine &TM) { Data16bitsDirective = "\t.half\t"; Data32bitsDirective = "\t.word\t"; Data64bitsDirective = 0; // .xword is only supported by V9. ZeroDirective = "\t.skip\t"; CommentString = "!";

Hello > I really need in my backend value for this section, distinct from > default. Where can I set it? It was renamed to ReadOnlySection. You might want to check the logic inside CodeGen/TargetLoweringObjectFileImp.cpp (in particular - TargetLoweringObjectFile::SelectionSectionForGlobal) to see how it's used. -- With best regards, Anton Korobeynikov Faculty of Mathematics and

I'm going to file this bug but it's kind of a blocker for me so maybe someone has time to look at it. Should be nearly trivial to fix. It's a bug in the way the "section" attribute of functions is processed. Consider the following code: void x(int i) __attribute((section(".mySection,\"aw\", at progbits#"))); void x(int i) { } If you compile this

Should be nearly trivial to fix. I don't think this is a bug, but a misfeature in GCC due to the way it does (non-)escaping. Joerg
