From: Greg Hackmann <ghackmann@xxxxxxxxxx> The current definition of ASM_EXPORT doesn't work properly with clang, according to https://bugs.llvm.org//show_bug.cgi?id=27250#c3 it relies on gcc specific behavior. Change the constraint from an intermediate to an output expression which works with both gcc and clang.
