Build works fine with 8.2.0-13

Apparently the volatile qualifier outside of functions is the culprit. The code compiles without errors when removing it from the affected asm blocks.

asm(".code32");
asm(".equ BASE,0xFFFFFFFF80000000");
asm(".equ PHYS_BASE,0xFFFFFFFF00000000");
// ...
asm(".code64");

The optional volatile qualifier has no effect. All basic asm blocks are implicitly volatile.

Just removing them should be fine
