Charlie Turner 364f2f3fcf Emit Tag_ABI_FP_denormal correctly in fast-math mode. ... The default ARM floating-point mode does not support IEEE 754 mode exactly. Of relevance to this patch is that input denormals are flushed to zero. The way in which they're flushed to zero depends on the architecture, * For VFPv2, it is implementation defined as to whether the sign of zero is preserved. * For VFPv3 and above, the sign of zero is always preserved when a denormal is flushed to zero. When FP support has been disabled, the strategy taken by this patch is to assume the software support will mirror the behaviour of the hardware support for the target *if it existed*. That is, for architectures which can only have VFPv2, it is assumed the software will flush to positive zero. For later architectures it is assumed the software will flush to zero preserving sign.
