[openssl-dev] 32 bit compilation of armv8 assembly support(openssl-1.0.2a)

[gaurav maheshwari]

I am compiling using the linaro aarch64 compiler for ILP32 ABI. *linux-armv4
*compilation
with option -march =armv8_a  giving lots of compilation errors as compiler
does not
supports mnemonics  . So I have tried to compile with new configuration for
ilp32
with "aarch64_asm".

"linux-armilp32","gcc: -O3 -mabi=ilp32 -Wall::-D_REENTRANT::-ldl:
SIXTY_FOUR_BIT RC4_CHAR RC4_CHUNK  DES_INT DES_UNROLL BF_PTR:
${aarch64_asm}::dlfcn:linux-shared:-fPIC:-mabi=ilp32:
.so.\$(SHLIB_MAJOR).\$(SHLIB_MINOR)",

In compilation with this configuration getting error
* "cannot represent BFD_RELOC_64 relocation in this object file
format" *in sha1-armv8.s.


linaro compiler path ("
http://releases.linaro.org/14.11/components/toolchain/binaries/aarch64-linux-gnu
").
