So, the main question is not about triggering condition, but about the
behavior itself. Is it correct to flush and reload all constants ? They are
constants after all, they are even not stored in .data section but inlined

Of course if the GIMPLE level doesn't care about the barrier then it doesn't

can just remove this barrier completely.
Not clear to me, what happens e.g. for register variables?

this turns on the cmpelim pass after reload and in a few examples and a
couple of benchmarks I noticed a number of comparisons getting deleted.
A similar patch for AArch32 is being tested.

OK? Built and tested on aarch64-linux-gnu with no regressions.
Thanks,
