At Red Hat we +generate a gdb-index as part of the build process, and we would +ideally like to have reproducible builds: for the same source, +compiled with the same tool-chain, we should get the exact same output +binary. And we do .... except for the index. + +Now we could simply force GDB to only use a single worker thread when +we build the index, but, I don't think the idea of reproducible builds +is that strange, so I think we should ensure that our generated +indexes are always reproducible. + +To achieve this, I propose that we add an extra step when building the +gdb-index file. After constructing the initial symbol hash table +contents, we will pull all the symbols out of the hash, sort them, +then re-insert them in sorted order. This will ensure that the +structure of the generated hash will remain consistent (given the same +set of symbols). + +I've extended the existing index-file test to check that the generated +index doesn't change if we adjust the number of worker threads used. +Given that this test is already rather slow, I've only made one change +to the worker-thread count.
