Reid Kleckner f168f78702 [PDB] Improve error handling when writes fail ... Handle PDB writing errors like any other error in LLD: emit an error and continue. This allows the linker to print timing data and summary data after linking, which can be helpful for finding PDB size problems. Also report how large the file would have been. Example output: lld-link: error: Output data is larger than 4 GiB. File size would have been 6,937,108,480 lld-link: error: failed to write PDB file ./chrome.dll.pdb Summary -------------------------------------------------------------------------------- 33282 Input OBJ files (expanded from all cmd-line inputs) 4 PDB type server dependencies 0 Precomp OBJ dependencies 33396931 Input type records ... snip ...
