/* There appears to be a bug in the MIPSpro linker that causes GOT_DISP
relocations against two unnamed section symbols to resolve to the
same address. For example, if we have code like:
lw $4,%got_disp(.data)($gp)
lw $25,%got_disp(.text)($gp)
jalr $25
then the linker will resolve both relocations to .data and the program
will jump there rather than to .text.
We can work around this problem by giving names to local section symbols.
This is also what the MIPSpro tools do. */
