1. Why store in memory on the stack only to load it again?
2. Depending on how this is compiled it could use the GOT which isn't a good idea
3. Dollars in a C identifier sound like a bad idea
4. Relaxations need to be disabled for the address calculation specifically otherwise it will be relaxed to be GP-relative, which is clearly unhelpful
In short this really just needs to be done in assembly as the standard `.option push; .option norelax; lla gp, __global_pointer$; .option pop`.
