Assembler change immediate value of one assembly instruction

jucimar

I am using the KEIL MDK-5, assembly. The project compiles without some problems, but when i see the disassembly the assembler change the inmediate value

Assembler substitute one instruction for another

My code:

The instruction: SUBS    R2,#0xC7

the assembler: 0x000006BC 3A00      SUBS     r2,r2,#0x00

When it changes the immediate 0xC7 change all results of my process.

Somebody saw something simlar?

    The image shows that the relevant source file has uncommitted changes.

    Is it possible that source file has changed since the last compilation (which is the compilation instance being utilized when running the binary)?
