Subject: remove some incorrect and unimplemented atomic builtins (e.g.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b0ed3029d96e31dfa71a61ac5aa8d04710e0fb12;p=clang

remove some incorrect and unimplemented atomic builtins (e.g.
__sync_umin_and_fetch), add some missing atomic builtins (e.g.
__sync_fetch_and_nand) and reorder the list to match the GCC
documentation.  The builtins still need work and codegen
implementation, more patches coming.
