#3678: Build failure on SPARC64 architecture
 Reporter: churanov.port.maintainer@… | Owner: pdimov
     Type: Bugs | Status: new
Milestone: Boost 1.42.0 | Component: smart_ptr
  Version: Boost 1.41.0 | Severity: Showstopper
 Keywords: |
 Boost 1.40.0 fail to build on SPARC64 machines.

 The issue arises when code of smart_ptr is assembled. The
 "boost/smart_ptr/detail/sp_counted_base_gcc_sparc.hpp" file contains
 SPARC-specific assembly for atomic compare-and-swap implementation and
 assembler rejects the code generated by the compiler out of that function.
 The generated code contains a "cas" instruction where first operand is a
 memory reference with complex addressing (register and offset). According
 to the SPARC v9 manual only register containing stored address may go

 The patch for the issue was created, but a single test in
 "libs/smart_ptr/test" fails.

 The patch is at http://alexanderchuranov.com/boost-port/boost-1.41-sparc64
