Hi, I'm building a new backend which can only load very limited range of imm. So I decided to use constant pool, and place constant pool entries close enough to instructions use the entries (we have very limited range PC-relative memory load). However, lld & llc output the object files that gather all constant pool entries into one section. How can I make them mix these entries into code

Hi there, I've created a bug on llvm: http://www.llvm.org/bugs/show_bug.cgi?id=9582 Basically, ARM, Thumb and data mapping symbols should have been exported in the ELF file, so the linker can work correctly. I can do the change and create some test cases, but I haven't been paying much attention to recent MC developments. Is ArmAsmPrinter the place to change for that, or is there an MC

Hi Reed, > I'm wondering if there is already some mechanism where I can assign literals > to the text section and get a label for where it has been stored. I think putting them in the text section is reasonably simple, though doesn't have a generic "pleasePutConstantsAfterFunctions()" call in LLVM. A good place to start would be the reverse of my recent patch to AArch64

I am working towards a more complete solution for large constants in mips 16 (ala Arm constant islands and such). That is part of why I'm busy expanding all macros being emitted in the mips 16 compiler (almost done). I'm wondering if there is a poor mans approach for large constants that can be done very simply that I can add just for now. Gcc mips 16 places them after the function

Hi, I'd like to generate constants inside .text in order to use ip-relative loads, when the code model is "large". How can I do this?

...lly the AArch64 backend did the same thing but I switched to the x86 model back in February. Which means thar r175258 is a nice potted (but reversed) description of all the steps needed. Ignore the more baroque parts of AArch64ConstantIslandsPass.cpp, yours will probably only have to add a bunch of CONSTPOOL_ENTRYs at the end of the function (the doInitialPlacement method, though even that does more than you need). I'll watch with interest to see how you handle it, AArch64 will probably have the same issues in the large code model. Cheers. Tim.

Why did you take out the constant island code for Arm 64? Just did not need it?
