Hi!

I try compile a sample file using the __ROR (rotate right) command. The linker gives me the error: undefined reference to `__ROR'.

Then i have seen that the core function __ROR is not defined in "core_cmInstr.h" (CMSISv2p00_LPC11Uxx) and so I added it by my own:

__attribute__( ( always_inline ) ) __STATIC_INLINE uint32_t __ROR(uint32_t op1, uint32_t op2)
{

  __ASM volatile ("ror %0, %0, %1" : "+r" (op1) : "r" (op2) );
  return(op1);
}

but i still get the same linker error.

µC: LPC11U14F
LPCExpr: v5.1.0 [Build 2048] [2013-02-05]

Hm, it should be a core instruction:

Any suggestions?

#1 Try

__attribute__( ( always_inline ) ) static __INLINE uint32_t __ROR(uint32_t op1, uint32_t op2)
{

  __ASM volatile ("ror %0, %0, %1" : "+r" (op1) : "r" (op2) );
  return(op1);
}

#2 Add it[COLOR=Red] inside GNU[/COLOR] (#elif (defined (__GNUC__)) of "core_cmInstr.h" :eek:

#3 Compile your CMSIS (both, Debug and Release)
