-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Build took 41:02 with these options: ac_add_options --enable-chrome-format=flat ac_add_options --disable-optimize ac_add_options --enable-debug-symbols ac_add_options --disable-crashreporter ac_add_options --disable-updates ac_add_options --disable-tests ac_add_options --without-intl-api ac_add_options --enable-jemalloc
Builds took 37:12, 34:58 with these additional options: mk_add_options "export COMPILE_PDB_FLAG=" mk_add_options "export HOST_PDB_FLAG=" mk_add_options "export MOZ_DEBUG_FLAGS=-Z7" (removed ac_add_options --enable-debug-symbols) That's a 9.3% - 14.8% improvement [0][1]. I noticed that PDB files were still generated; is that expected or did I miss something in the configuration options? Also, I did run into an issue where WinDbg wasn't able to show me source code for some functions in xul.dll (which normally it should have been able to). I'll keep investigating to see if that was a fluke or if there are some STR I can post here.
