Hey, I have an odd problem with printing prefixed global symbols in my AsmPrinter. In my MCAsmInfo subclass implementation, I set GlobalPrefix = "%"; because my assembler needs this to avoid name collisions. Now, whenever a global symbol (be it a label, mbb operand ,etc.) gets printed, it is encapsulated in quotes. With other chars than '%' everything is okay... I also

Hi there, I'm having a hard time with promoting operands from i1 to i32 in my backend... I have to register classes, VTs are i1 and i32. The i1 registers are only for predication and conditional jumps, so I want to use them with brcond, setcc. There are no instructions to directly load a value in an i1 register or to copy between i1 and i32, so I need the DAG Legalizing Pass to not generate

Hi, is there any documentation on which functions clang assumes to be provided by a freestanding environment? Are that really only memcpy, memmove, memset and memcmp? Greetings, Jan
