--- Comment #2 from Matthias Schiffer <mschif...@universe-factory.net> ---
The problem seems to be that the gp init sequence
li $2,%hi(_gp_disp)
addiu $3,$pc,%lo(_gp_disp)
sll $2,16
addu $2,$3
is generated very late and does not appear in the RTL in any way, so optimizing
passes are not aware of the $3 (and possibly $2?) clobber. I don't know enough
about GCC internals for further analysis.
