There are a lot of problems in the code:

• extern definitions should be moved to a header file search.h, included by all .c files.
• C source files should not include other .c files
• global variables are error prone and in your case non existent, consider passing arguments instead of trying to refer to local variables in the main function.
• the bash script should be more consistent: object files should have the same basename as the corresponding source file and compiled with consistent compiler arguments. Consider using a Makefile instead of a bash script or at least echo the commands as they are executed.

Here are some proposals:

Makefile:

You have a segmentation fault because unitTasks[j][0] is null pointer since your array initialization loop starts at 1. Also, you should try to compile in debug mode (without -DNDEBUG) and thus you would get an assertion failure when the null handle is used.

As stated in the comments, I wouldn't try to create a function to make the ids, as there will likely be some "quirky" ones in there that might not follow that logic.

If you're just go through each letter search they have it divided by and get the id directly by the player url.

First, the behavior of your calls to setjmp is not defined by the C standard because they violate the constraints in C 2018 7.13.1.1 4 and 5:

An invocation of the setjmp macro shall appear only in one of the following contexts:

— the entire controlling expression of a selection or iteration statement;

— one operand of a relational or equality operator with the other operand an integer constant expression, with the resulting expression being the entire controlling expression of a selection or iteration statement;

— the operand of a unary ! operator with the resulting expression being the entire controlling expression of a selection or iteration statement; or

— the entire expression of an expression statement (possibly cast to void).

If the invocation appears in any other context, the behavior is undefined.

For example, in if( ( sjr = setjmp( *s_pEnvA ) ) == 0 ), the setjmp invocation is not the entire controlling expression, it is not an operand of a relational or equality operator (<, <=, >, >=, ==, or !=), it is not the operand of !, and it is not the entire expression of an expression statement.

Second, longjmp can only jump up the call stack, to functions that are still executing. Once a call to a function stops executing (as when it returns), you cannot jump back into that call. Your code saves the context in routineB, then jumps to routineA (which ends execution of routineB), then attempts to jump to the saved context. But C 2018 7.13.2.1 2, about longjmp says:

… if the function containing the invocation of the setjmp macro has terminated execution in the interim,… the behavior is undefined.

I can't understand undefined named operand error. Do I need to define the operand in the template somewhere? In the example in https://www.keil.com/support/man/docs/armclang_ref/armclang_ref_qbn1517569205870.htm, the operands in the template are just used without defining.

Yes, you need to define them either in the inputs or the outputs of the asm statement. The examples you link all define all the names they use. Your code just defines tag_val and data_val there, so ptr_val and ptr_addr are undefined.

Split URL string into variables and its values, than go through them and create for each one new meta element.

How about something like this?

I would like to know if release+acquire can violate happens-before.

Happens-before relationship cannot be "violated", as it is a guarantee. Meaning, if you established it in a correct way, it will be there, with all its implications (unless there is a bug in the compiler).

However, establishing just any happens-before relationship doesn't guarantee that you've avoided all possible race conditions. You need to establish carefully chosen relationships between relevant operations, that will eliminate all scenarios when data race is possible.
