[LLVMdev] Problem using a label to a basic block
...c block) with : -- Loading the link register with the address of the new basic block -- and generating a 'CALL_R' which in the end results in a 'branch to register' (but, for llvm, it is treated as a call) So: __BB_2: ... call_to_reg Rx ... results in: __BB_2: ... load_immediate R15, __BB_3 branch_to_reg Rx __BB_3: ... where __BB_2 falls through to __BB__3 This works when the optimization level is low. At higher optimization levels I am observing the following : load_immediate R15, __BB_3 branch_to_reg Rx __BB_3: branch_to __BB_22 is converted into l...

[LLVMdev] Problem using a label to a MachineBasicBlock
...t;< MAI.getLabelSuffix(); EmitEOL(); } --- When I disable the assertion, I observe the following: The different labels for the machine basic blocks are emitted, but the two new basic blocks that were created, also have a common extra label '_tmp0' --- .text .globl _foo _foo: .... load_immediate R15, __BB0_1 branch_to_reg R1 _tmp0: _BB0_1: ... load_immediate R15, __BB0_2: branch_to_reg R2 _tmp0: // *** duplicate unnecessary label, _tmp0 is not used _BB0_2 ... --- Any idea how this can be resolved in a clean way ? Thanks, Jeroen Dobbela...
