--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Unfortunately it breaks bootstrap on powerpc64le-linux:
../../../libgcc/libgcc2.c: In function ‘__mulvti3’:
../../../libgcc/libgcc2.c:396:1: internal compiler error: Max. number of
generated reload insns per insn is achieved (90)
Vlad, any thoughts on this?
Does IRA have any code which would estimate if two pseudos where one dies in a
simple move insn and another one defined in there can be sharing the same
register? Should IRA itself estimate in those cases that a noop move would be
for free (0 cost)?
Or would ^^r instead of ??r work here? Or something else?
