Global variable initilization

I am using Uvision 3 , Generating code for lpc2214

Here below is my simple code

int x=10 ; int y=100 ;

void ram_fun(void); void delay(void);

void main() { ram_fun(); while(1) { ; } }

void ram_fun(void) __ram { x = y/x; }

Here below I am pasting a section of the disassembly shown by .COD file generated by compiler

*** Disassembly of Segment '?C_INITSEG' when instruction is x = y/x: 00000130 40000498 DD 0x40000498

00000134 400004C4 DD 0x400004C4

Now if i replace x = y/x with x = x+y and no other changes in code or compiler settings than the disassembly shown by .COD file for ?C_INITSEG segment is as below.

*** Disassembly of Segment '?C_INITSEG' when instructio is x = x+y: 00000130 40000000 DD x

00000134 40000008 DD x + 0x8

00000138 0000000A DD 0xA

0000013C 00000064 DD 0x64

00000140 40000498 DD 0x40000498

00000144 400004B0 DD 0x400004B0

which shows the difference between ?C_INITSEG segment.

I have read somewhere that ?C_INITSEG is responsible for initilization of the global variables.

This disassembly clearly shows that there is no initlization code for Global variables when we have division operation in our code. Which agrees with my observation of the values of variables.

Please note that the replcement of division instruction with addition is only difference in both the case. All other code and settings are same.

If I remove __ram attribute than all works fine.

Can anybody explain this?

Is it problem with keil?

Thanks and regards.
