New Revision: 278788
URL: https://svnweb.freebsd.org/changeset/base/278788
Log:
Pull in r201130 from upstream clang trunk (by Ted Kremenek):
Fix PCH deserialization bug with local static symbols being treated
as local extern.
This triggered a miscompilation of code using Boost's
function_template.hpp when it was included inside a PCH file. A
local static within that header would be treated as local extern,
resulting in the wrong mangling. This only occurred during PCH
deserialization.
Fixes <rdar://problem/15975816> and <rdar://problem/15926311>.
This fixes a crash in audio/murmur, which is using both PCH and Boost.
Direct commit to stable/10 and stable/9, since head has clang 3.5.1,
which already includes this change.
