Hi all, I am writing a back-end for a processor that has complex type registers. It has two functional units to perform complex multiplications. From clang, I emulate a complex multiplication using vectors and, at the IR, I got this tblgen-friendly pattern (real component) : (set RARegs:$dst, (insertelt RARegs:$src, (i16 (trunc (add (ncmul (sext (i16

On a rather full customer web server, I am trying to track down whose web site script is trying to make outbound network connections when they should not be. In /etc/security/audit_control, I added to the flags line dir:/var/audit flags:lo,aa,-nt minfree:5 to log failed network connection. When I try an make an outbound connection to something that is blocked in pf, it seems to sometimes work.

That’s a good question, by default when emitting the object file I choose COFF but it embeds dwarf and not codeview in the end.. there probably is a way to do it or at least it must be implemented if not yet.. Lets imagine I manage to do that.. when you say there is nothing to do, I still must have a PDBFileBuilder to copy the codeview data inside the EXE PDB right ? I cannot insert them easily in

Hi all, Tuning my TargetAsmPrinter implementation in the back-end side, I discovered that the address space number is not passed down while emitting global variables with constant initializers. The information is dropped at AsmPrinter::EmitGlobalConstant() function call which defaults it to zero. I would like to emit target-dependent asm directives depending on the address space of constant

Ok I understand more what you meant. In fact I don’t care about the pdb size, at least as a first step, so it won’t be a problem for me to have duplicated symbols. Concerning TypeIndices my plan if possible is not to generate a pdb for my jit and merge it, but instead directly extract debug info from a DwarfContext just after llvm::object::ObjectFile is emitted by the JIT engine and complete the

Ok I see.. what do you mean by “making sure to de-duplicate records as necessary” ?
