From: Xin Wang <[email protected]> The use of UOItype with mode(OI) for 16-byte atomic operations is non-standard. The OI mode is not defined in machmode.def and exists only as an ad-hoc construct in libgcc/sync.c.
This patch replaces it with UTItype using mode(TI), which is the standard GCC machine mode for 16-byte integers (Tetra Integer). The size argument is also corrected from 8 to 16 to match the actual operand width. libgcc/ChangeLog: * sync.c: Replace UOItype with UTItype and use mode(TI) pass 16, not 8, to DEFINE macro.
