Given the concerns about increased memory consumption and run-time
overhead in patch 3 and the changes to the source interleaving algorithm
in patches 4 and 5, I'd go with a modified version of my original RFC, i.e.
- patches 1 and 2 from this series
- the rfc patch to interleave sources in record-btrace.c
- patch 6 from this series
This will leave us with two source interleaving algorithms, one for a
consecutive range of memory, and one for a sequence of instructions
in the order in which they were recorded.
Both will use a slightly modified dump_insn to print instruction tuples.
I'm dropping the idea of preparing a vector of instructions to print and
and of trying to shoehorn record instruction-history's source interleaving
Does that sound OK?
