scan_one_insn() doesn't keep REG_N_REFS accurate
- To: gcc-patches at gcc dot gnu dot org
- Subject: scan_one_insn() doesn't keep REG_N_REFS accurate
- From: Alexandre Oliva <aoliva at redhat dot com>

scan_one_insn() will optimize two-address insns that require operand1
to match operand0 by introducing a copy insn from operand1 to operand0
before the two-address insn. However, even though it increments
REG_N_SETS, it doesn't increment REG_N_REFS (that should be REG_N_SETS
+ number of uses).
This causes local-alloc to abort() if a pseudo was set once and used
once, before the transformation. update_equiv_regs() would note that
REG_N_REFS was 2 and that the first set of the register was movable,
so it would set the replace flag for the pseudo. However, when it got
to the second set, it would call no_equiv(), clearing init_insns and
replacement, but not the replace flag. Then, when it got to the use
of the pseudo, it would abort() because init_insns was (const_int 0)
when processing the REG_DEATH note, or crash because equiv_insns would
be set to NULL.
Unfortunately, I can't post the test-case that triggered the problem
on mn10300-elf, but I can give more concrete scenario presenting the
relevant insns before the transformation by scan_one_insn() and at the
point of the crash in update_equiv_regs().
Before:
(parallel[
(set (reg:SI 63)
(div:SI (const_int 1 [0x1])
(reg/v:SI 60)))
(set (reg:SI 64)
(mod:SI (const_int 1 [0x1])
(reg/v:SI 60)))
] ) 25 {divmodsi4}
(set (reg:SI 0 d0) (reg:SI 63))
After:
(set (reg:SI 63)
(const_int 1 [0x1]))
(expr_list:REG_EQUIV (const_int 1 [0x1]) (nil))
(parallel[
(set (reg:SI 63)
(div:SI (reg:SI 63)
(reg/v:SI 60)))
(set (reg:SI 64)
(mod:SI (reg:SI 63)
(reg/v:SI 60)))
] ) 25 {divmodsi4}
(expr_list:REG_DEAD (reg/v:SI 60)
(expr_list:REG_UNUSED (reg:SI 64)
(nil)))
(set (reg/i:SI 0 d0)
(reg:SI 63))
(expr_list:REG_DEAD (reg:SI 63) (nil))
I'm tempted to check this in as obviously correct, but, just in case,
I'll ask: is this ok to install?
