Re: Where is the splitting of MIPS %hi and %lo relocations handled?

I am going to try to fix:

Which is a problem where a %lo relocation gets separated from its
corresponding %hi.

What is the mechanism that tries to prevent this from happening?  And
where is it implemented?


This implemented by having the assembler sort the relocations so that
each %lo relocations follows the appropriate set of %hi relocations.
It is implemented in gas/config/tc-mips.c in append_insn.  Look for
reloc_needs_lo_p and mips_frob_file.

At first glance the assembler does appear to handle %got correctly, so
I'm not sure why it is failing for you.

Did you look at the assembly fragment in the PR?


Is it correct in that there is a pair of %got/%lo in the middle of another %got/%lo pair?
