Author: sepavloff Date: Wed Jul 4 23:24:29 2018 New Revision: 336312 URL: http://llvm.org/viewvc/llvm-project?rev=336312&view=rev Log: [demangler] Avoid alignment warning
The alignment specified by a constant for the field `BumpPointerAllocator::InitialBuffer` exceeded the alignment guaranteed by `malloc` and `new` on Windows. This change set the alignment value to that of `long double`, which is defined by the used platform. It fixes https://bugs.llvm.org/show_bug.cgi?id=37944.
