I add the basic thread sanitizer interface, which is the __tsan_{read, write}() function, please check it.
The commit is 807ffbf.
It will call the check_access() function and pass the operation type, like UCSAN_ACCESEE_WRITE to specific the write operation.

1. 所以【#define UCSAN_ACCESS_WRITE 0x1】，會傳1給我囉
2. check_access的parameters多一個【unsigned long ip】，我會用到嗎

Yes.
But, you can use the bitwise AND to the macro name ( like UCSAN_ACCESS_WRITE & type ) to get the type.

2. check_access的parameters多一個【unsigned long ip】，我會用到嗎

Yes.
It will get the return function address.

See the __builtin_return_address in
https://gcc.gnu.org/onlinedocs/gcc/Return-Address.html

I create the PR for the find_watchpoint().

This patch set the basic idea of how the watchpoint store the information of the object that we want to detect the data race.
And how the watchpoint will be maintained.
