> Chandler’s complex arithmetic changes are also in the range: r219557 in clang. We saw it change the code in mandel-2 significantly. mandel-2 is broken on hard FP ABI systems, btw. The reason is simply: we're emitting a call to __muldc3 with AAPCS VFP calling convention, however, the function expects softfp (AAPCS) calling conv and reads garbage from GP registers. I'm working on fix.
