[PR106746] drop cselib addr lookup in debug insn mem
|
||||
|
||||
The testcase used to get scheduled differently depending on the
|
||||
presence of debug insns with MEMs. It's not clear to me why those
|
||||
MEMs affected scheduling, but the cselib pre-canonicalization of the
|
||||
MEM address is not used at all when analyzing debug insns, so the
|
||||
memory allocation and lookup are pure waste. Somehow, avoiding that
|
||||
waste fixes the problem, or makes it go latent.

A recent change only initializes the regs.how[] during Dwarf unwinding
|
||||
which resulted in an uninitialized offset used in return address signing
|
||||
and random failures during unwinding. The fix is to encode the return
|
||||
address signing state in REG_UNSAVED and REG_UNDEFINED.
