anjiahao 7dfbd14eba libc: add instrument api support ... Add registration function instrumentation API, which can achieve instrumentation of entering and exiting functions through the compiler's functionality. We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all source, or add '-finstrument-functions' to CFLAGS for Part of the source. Notice: 1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function, becuase bss not set. 2. Make sure your callbacks are not instrumented recursively. use instrument_register to register entry function and exit function. They will be called by the instrumented function Signed-off-by: anjiahao <anjiahao@xiaomi.com>		2023-12-11 02:06:51 -08:00
