Compiling Issues on AArch64

[lrh12580]

Hi All,

I've got a compiling issue on one AArch 64 machine. The error message is

./tcmalloc/internal/percpu_tcmalloc.h:483:4: error: undefined named operand 'rseq_sig'

It seems that the RESQ support was added on Issue #50, but I am stilling get the compiling issues.

Does someone have met similar issues and be able to solve this?

Great Thanks!

Can you provide some more information about your compiler and which commit you're building from?
