Hello to all,

I am working on a project on the STM32 microcontroller, using Ride7 toolchain.
When I am trying to use the RBIT instruction: RBIT Rd, Rn the compiler will replace the Rn register by default by R0.
The problem is that I cannot use the R0 in that instruction. In other hand, why the compiler changes the register? Normally an assembly code has not to be modified. There is a patch for this issue?
Thanks to all.
