Subject: shrink SOURCE_LOCATION_OFFSETS to use 4-byte entries instead of 8-byte
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=090d9b53e32bb30d9e74de895bb59b409bd49e00;p=clang

shrink SOURCE_LOCATION_OFFSETS to use 4-byte entries instead of 8-byte
entries, shaving 100K off the PCH file for cocoa.
