| | | | | | | | | | | | | | | | | | | | | PR20844: If we fail to list-initialize a reference, map to the referenced type before retrying the initialization to produce diagnostics. Otherwise, we may fail to produce any diagnostics, and silently produce invalid AST in a -Asserts build. Also add a note to this codepath to make it more clear why we were trying to create a temporary. This should fix assertions when parsing some forms of incomplete list intializers.

| | | | | | | | | | | | | | | | | | | | | Fix clang 6.0.0 compiler warnings in binutils Latest clang git has a warning -Wnull-pointer-arithmetic which will trigger a -Werror failure. Addition and subtraction from a null pointer is undefined behaviour and could be optimized into anything. Furthermore, using the difference between two pointers and casting the result back to a pointer is not portable since the size of ptrdiff_t does not necessary have to be the same as size of void* (this happens e.g. on CHERI). Using intptr_t instead fixes this portability issue and the compiler warning.

Both @aaron.ballman and @mclow.lists felt that adding this workaround to the libc++ headers was the wrong way, and it should be fixed in clang instead. Here is a proposal to do just that. I verified that this suppresses the warning, even when -Wsystem-headers is used, and that the warning is still emitted for a declaration outside of system headers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix for mlx4en(4) to properly call m_defrag(). The m_defrag() function can only defrag mbuf chains which have a valid mbuf packet header. In r291699 when the mlx4en(4) driver was converted into using BUSDMA(9), the call to m_defrag() was moved after the part of the transmit routine which strips the header from the mbuf chain. This effectivly disabled the mbuf defrag mechanism and such packets simply got dropped. This patch removes the stripping of mbufs from a chain and loads all mbufs using busdma. If busdma finds there are no segments, unload the DMA map and free the mbuf right away, because that means all data in the mbuf has been inlined in the TX ring. Else proceed as usual. Add a per-ring rounter for the number of defrag attempts and make sure the oversized_packets counter gets zeroed while at it. The counters are per-ring to avoid excessive cache misses in the TX path.
