#5327: MPS ISA issue related to ll / sc
----------------------------------------------------+-----------------------
Reporter: Oliver Kowalke <oliver.kowalke@â¦> | Owner: pdimov
Type: Bugs | Status: new
Milestone: To Be Determined | Component: smart_ptr
Version: Boost 1.45.0 | Severity: Showstopper
Keywords: mips ll sc assembler error |
----------------------------------------------------+-----------------------
boost/smart_ptr/detail/sp_counted_base_gcc_mips.hpp uses in its inline
assembler ll/sc opcode for atomic operations (increment decremet).
Both opcodes are available since MIPS II ISA - unfortunately gcc assumes
MIPS ISA I as default - so the inline assembler from
sp_counted_base_gcc_mips.hpp triggers an assembler error:
'opcode not supported on this processor : mips1 (ll/sc)'
The header could be patches so that it instructs the CPU to switch to ISA
II for ll/sc.
