dim 897775d6ee When one attempts to compile the tree with -march=i386, which also used ... to be gcc's default before r198344, calls to atomic builtins will not be expanded inline. Instead, they will be generated as calls to external functions (e.g. __sync_fetch_and_add_N), leading to linking errors later on. Put in a seatbelt that disables use of atomic builtins in libstdc++ and llvm, when tuning specifically for the real i386 CPU. This does not protect against all possible issues, but it is better than nothing.		2011-11-06 14:07:23 +00:00
