[LLD] Writing thunks before the corresponding section
Hi,
MIPS LA25 thunk is used to call PIC function from non-PIC code.
Usually it contains three instructions:
lui $25, %hi(func)
addiu $25, $25, %lo(func)
j func
We can write such thunk in an arbitrary place of the generated file.
But if a PIC function requires the thunk is the first routine in a
section,...

[LLD] RFC Range Thunks Implementation review for ARM and Mips
This RFC is primarily to support the review of the range extension
thunks implementation of lld. This concerns ARM and Mips as all of the
thunk creation step is skipped over if the target doesn't need thunks.
Mips LA25 Thunks are not range extension Thunks but these are
generated using the same code, I've kept the behaviour the same as it
is now, although the implementation is obviously slightly different in
the detail.
Recap of range extension thunks
