Um, except again, we are verifying no regressions in test results, plus
no serious (>5%) regressions in compile time or execution time.
You also forgot that the code has already been reviewed by global
maintainers who were working on the branch, and will again be design
reviewed before committing to the main branch.
Plus it includes both high-level design, and user-level documentation
Finally, the merge in question, plus the document describing the merge
and it's criteria, was explicitly approved by the GCC Steering
Committee.

The HP merge was completely different than the above.
It seems like you are trying to degrade gcc here by comparing the SSA
merge to the HP merge, which is clearly a dumb comparison.
Just because certain gdb people screwed that merge up by not requiring
more doesn't mean GCC will do the same, as evidenced by the above.
