Hi All, I need to print some extra information about libcall names in assembly. Libcall names are managed as ExternalSymbols in LLVM. How do I access these ExternalSymbols from Asmprinter? AsmPrinter uses class Module that lists all the global variables (including extern variables) and functions (include extern functions). But it does not list any information about the libcalls

OK, here's a new patch that adds the infrastructure and the implementation for X86, ARM and PPC of GetInstSize and GetFunctionSize. Both functions are virtual functions defined in TargetInstrInfo.h. For X86, I moved some commodity functions from X86CodeEmitter to X86InstrInfo. What do you think? Nicolas Evan Cheng wrote: > > I think both of these belong to TargetInstrInfo. And

Hi all, FlexyCore, the company I am working for, use LLVM to generate binary for ARM platform. We are very fulfilled with LLVM, and FlexyCore will be pleased to contribute on this software. We need debug support in ARM binary, but, in LLVM 2.4, this support is not activated for ARM backend. Consequently, I made small modifications in order to activate it (see the patch in attach file).

Inline asm should work in the MCJIT just as well as it does in statically compiled code. It's the same code path for both. The error you're seeing indicates that something isn't configured in a way the compiler understands. -Jim On May 12, 2012, at 10:48 AM, Ashok Nalkund wrote: > Can you also tell about inline-asm support in MCJIT for x86?

Can you also tell about inline-asm support in MCJIT for x86?

I'm so close to having LLVM build on PowerPC. If there's any PowerPC experts, help? Lines like this: outs() << "[" << format("%2d", i) << "]" << "(sec " << format("%2d", int16_t(symbol->SectionNumber)) << ")" << "(fl 0x" <<
