Subject: Sema/ObjC: Override search can generate a large search list, bump the base size
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b732fcebcf2ce5c24a29d660e9400d7dc9f86b69;p=clang

Sema/ObjC: Override search can generate a large search list, bump the base size
of the SmallPtrSet way up to avoid commonly reallocating the buffer size.
 - I didn't see a good argument against it, so I bumped the limit to cover the
   max size we see during parsing Cocoa.h.
