Strange characters in System.map file

[naveen yadav]

Hi all ,


we are using gcc 4.4.1 and build cross tool chain with binutils 2.19.51.

I am building 2.6.30 kernel for ARM. It build and run well on my
target, but i am seeing some strange char in
System.map file

. .

c0064434 T NvRmPrivDfsDeinit
c0064540 t DfsIsr
c0064cf8 t T.285
c0064d3c t T.288
c0064f2c T NvRmDfsSetState
c0064ff0 t T.289
c0065078 T NvRmPrivDfsInit
c006607c t T.291                                        <<<Example
c00661c8 T NvRmPrivDvsInit

I found that c0064cf8 t T.285 function are small function which are
declared as static void

. . .
 For example :  The below static function  will not be there if we see
assembly code of the obj file.


static void DvsChangeCpuVoltage( NvRmDeviceHandle hRm,NvRmDvs* pDvs,
NvRmMilliVolts TargetMv)

{

NV_ASSERT(TargetMv >= pDvs->MinCpuMv);

NV_ASSERT(TargetMv <= pDvs->NominalCpuMv);

if (pDvs->CurrentCpuMv != TargetMv)

{

NvRmPmuSetVoltage(hRm, pDvs->CpuRailAddress, TargetMv, NULL);

pDvs->CurrentCpuMv = TargetMv;

}

}



instead it will be look like as  shown below.


0000205c <T.286>:
   205c:       e1a0c00d        mov     ip, sp

   2090:       e1a02005        mov     r2, r5
   2094:       ebfffffe        bl      0 <NvRmPmuSetVoltage>
   2098:       e7845006        str     r5, [r4, r6]
   209c:       e89da878        ldm     sp, {r3, r4, r5, r6, fp, sp, pc}



If i build kernel with O1 or O0 flag, these strange character
disappear. also i check on GCC 4.3.3 there is no problem .

Is there some flag to disable these strange characters ?

kind regards
