gas/
* symbols.c (S_FORCE_RELOC): Return true for indirect functions
even if !strict.
* expr.c (operand): Don't convert absolute symbols to constants
if S_FORCE_RELOC is true.
(expr): Only reduce subtractions between different symbols if
S_FORCE_RELOC is false for both of them.
* write.c (fixup_segment): Don't remove symbols if S_FORCE_RELOC
is true for them, regardless of their segment.
gas/testsuite/
* gas/i386/ifunc-2.s, gas/i386/ifunc-2.l: New test.
* gas/i386/ifunc-3.s, gas/i386/ifunc-3.d: Likeise.
* gas/i386/i386.exp: Run them.
