...and ARMv5 implementations do not require this restriction either, because high performance multipliers read all their operands prior to writing back any results."

Hi, I am using a cross compiler to compiler for the arm5 architecture. For this architecture it is not allowed that a destination register is also used as source register. In 2007 a patch was discussed at the mailing list, however my compiler still is producing this result. Does anyone know if this patch is actually applied? * I use the following arguments: llvm-gcc -mfpu=vfp -mlittle-endian
