David Blaikie 6715d6ec2e Fix quadratic performance during debug compression due to sections x symbols iteration. ... When fixing the symbols in each compressed section we were iterating over all symbols for each compressed section. In extreme cases this could snowball severely (5min uncompressed -> 35min compressed) due to iterating over all symbols for each compressed section (large numbers of compressed sections can be generated by DWARF type units). To address this, build a map of the symbols in each section ahead of time, and access that map if a section is being compressed. This brings compile time for the aforementioned example down to ~6 minutes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207167 91177308-0d34-0410-b5e6-96231b3b80d8		2014-04-25 00:48:01 +00:00
