Normally an ELF .o has two string tables, one for symbols, one for section names. With the scheme of naming sections like ".text.foo" where foo is a symbol, there is a big potential saving in using a single one. Building llvm+clang+lld with master and with this patch the results were: master: 193,267,008 bytes patch: 186,107,952 bytes master non unique section names: 183,260,192 bytes patch non unique section names: 183,118,632 bytes So using non usique saves 10,006,816 bytes, and the patch saves 7,159,056 while still using distinct names for the sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238073 91177308-0d34-0410-b5e6-96231b3b80d8
