ARM64 Linaro toochain Link error ( R_AARCH64_LD_PREL_LO19 )

Hi Experts,

I am getting following linker error from Linaro aarch64 tool chain( aarch64-linux-gnu-gcc, gcc-linaro-aarch64-linux-gnu-4.8-2014.03_linux),  for our code which uses  pBitReverseIndex, pSignTable  global pointers which is declared out side the assembly file.

Linking CXX executable decoder-app

The DCT assembly function uses BitReverseIndex, SignTable, CosineTable etc. declared inside DCT.c

We are using LDR instruction inside assembly to load the address of these tables :

LDR                 x17, pSignTable

LDR                 x15, pRevTable

These tables and pointers are declared DCT.c

const Int32 SignTable[4]= {1, 1, 1, -1};

const Int8 RevTable[16]= {0,1,2,3,4,5,6,7,0xc,0xd,0xe,0xf,8,9,0xa,0xb};

const Int8* const pRevTable = RevTable;

const Int32* const pSignTable = SignTable;

We also tried with ADR instruction which satisfies position independent coding. But we couldn't fix this issue.
