Hi,
I ran into a wrong code bug in code with deep template instantiation when
working on sdx::simd.
The root cause as described in commit summary is we skip prologue insns in
init_alias_analysis.
This simple patch fixes the issue, however, it's hard to reduce a case because
of heavy use of
templates.
Bootstrap and test on x86_64, is it OK?
It's a clear correctness improvement, but what's unclear to me is why
we'd want to skip them in the epilogue either.
