--- Comment #2 from Zdenek Sojka <zsojka at seznam dot cz> ---
If I understand the .reload dump correctly, r87 is not live in insn 289, but it
should be:
...
289: r416:SI=r87:SI+const(unspec[`*.LC9'] 1)
REG_EQUAL `*.LC9'
Creating newreg=417 from oldreg=87, assigning class GENERAL_REGS to
address r417
Change to class INDEX_REGS for r417
0 Non pseudo reload: reject++
alt=0,overall=1,losers=0,rld_nregs=0
Choosing alt 0 in insn 289: (0) =r (1) Ts {*leasi}
289: r416:SI=r417:SI+const(unspec[`*.LC9'] 1)
...
Insn 289: point = 104
...
r87 is added to live at bb2 start
...
r87: [107..246]
But maybe I misunderstand the dump - why is r87's live range 107..246, when it
is live at bb start?
