-
-NAND is ~(a1 & a2), but xtensa_expand_atomic does ~a1 & a2.
-That fixes libatomic tests atomic-op-{1,2}.

-Subject: [PATCH] gcc: xtensa: don't force PIC for uclinux target
-
-xtensa-uclinux uses bFLT executable file format that cannot relocate
-fields representing offsets from data to code. C++ objects built as PIC
-use offsets to encode FDE structures. As a result C++ exception handling
-doesn't work correctly on xtensa-uclinux. Don't use PIC by default on
-xtensa-uclinux.
