linker script with a default value of 0. If the heap is used when the heap size is set to
zero, the behavior is the same as when the heap usage exceeds the minimum heap
size. Namely, it overflows into the space allocated for the stack.
The heap and the stack use the unallocated KSEG1 data memory, with the heap
starting from the end of allocated KSEG1 data memory and growing upwards towards
the stack while the stack starts at the end of KSEG1 data memory and grows
downwards towards the heap. If enough space is not available based on the minimum
amount of heap size and stack size requested, the linker issues an error.

The compiler toolchain supports global pointer (gp) relative addressing. Loads and
stores to data lying within 32KB of either side of the address stored in the gp register
can be performed in a single instruction using the gp register as the base register.
