linux-toradex.git/arch/nds32/include/asm/ftrace.h, branch v5.3.2 Linux kernel for Apalis and Colibri modules nds32/ftrace: Support dynamic function tracer 2018-09-04T06:45:18+00:00 Zong Li zong@andestech.com 2018-08-15T03:00:08+00:00 6b1d6d2fba37129f690ee7e9164f225c55626cac This patch contains the implementation of dynamic function tracer. The mcount call is composed of three instructions, so there are three nop for enough placeholder.

nds32/ftrace: Support static function tracer 2018-09-04T06:45:17+00:00 Zong Li zong@andestech.com 2018-08-15T02:45:59+00:00 a18082575c664847d36c6ca030b09ce8d93aec2f This patch support the static function tracer. On nds32 ABI, we need to always push return address to stack for __builtin_return_address can work correctly, otherwise, it will get the wrong value of $lp at leaf function.
