compile error: x29 cannot be used in asm here

[Bran-Sun]

I am trying to compile on Kunpeng 920-4826 machine, but got this error

g++ -c -fPIC test_temp_L1.c -o test_temp_L1.o
test_temp_L1.c: In function 'void SGEMM_NN_L1(float*, float*, float*, long int, long int, long int)':
test_temp_L1.c:2727:1: error: x29 cannot be used in asm here
 }
 ^
Makefile:14: recipe for target 'test_temp_L1.o' failed

It seems like register x29 is the frame pointer and cannot be used directly. Can you check this problem, Thanks.

Hello! Thank you for your interest in this work.
Please check your GCC version.

Thanks, g++-8 works for me.
By the way, I notice that the interface of gemm miss some arguments like lda, will you support such arguments later?
