[llvm-dev] Emitting asm variable directive into MachineBasicBlock
Hello everyone, I am writing a MachineFunctionPass and need to insert int32 data values into my asm file. I achieved that by adding a GlobalVariable to the MachineFunction's Module which gets me something like: test: .long 0 @ 0x0 .size test, 4 at the Module's end. I need to access the data with PC relative instructions like LDR Rd, <label> (Rd := [label]), where the label range is limited (label range PC to PC+1020). This leads to the problem that the data might be too far away. The question I face is how to get the data into the corresponding BasicBlock. Can it be done with a MachineInstr? I am using the ARM backend, ARMv6m Architecture. Best regards, Julius Hiller -------------- next part -------------- An HTML attachment was scrubbed...
