I've got a customer project that emits a 18 MB .exe and 9 MB .exe.pdb; It takes about 6 minutes to link on their system, 2 minutes to link on mine (this a regullar lld -flavor link /opt:lldlto=0). the input is about 61mb of bitcode files (originally about 2100 object files) with debug info (both pdb and dwarf get emitted) stored in 5 .lib files, compiled with -O0 but with thin-lto (without thin-lto it wasn't faster). Is this something to be expected? Can I do something to improve t...
