Weird clock issue

Hullo guys, I'm using KEIL as the IDE to program LPC4357 . I have a problem with the CGU, as it says in the user manual , the BASE_M4_CLK is provided by the PLL1 by default. But in the register description of the BASE_M4_CLK register, the user manual says it is connected to the IRC by default !!! . When I started debugging in KEIL, without any system initialization (removed it from the assembly start-up code) , I found that KEIL is missing IDIVC and IDIVD registers !!! and also the BASE_M4_CLK register in the debugger is connected to the IDIVC !!
The attached picture shows it all.
I also noticed that the LPC library is missing the CCU .h and .c files.
Any explanation ??!!
