[LLVMdev] Virtual Studio hack in APFloat.h
...1 we’re on VS2013 at a minimum? I’d have hoped it would be more likely to work.
Thanks,
Pete

[PPC, APFloat] Add full PPCDoubleDouble to APFloat
...t to
build an abstraction between APFloat and the underlying data
representation? For example:
class APFloatPayload {
union Significand { integerPart part; integerPart *parts; } significand;
int exponent;
public:
// *Significand() operations.
};
class APFloat {
fltSemantics *semantics;
fltCategory category;
APFloatPayload first;
Optional<APFloatPayload> second; // for PPCDoubleDouble
};

[LLVMdev] Soft floating point support
This patch supplies software IEEE floating point support.
The comment from the patch reproduced below says all there is
to say.
This patch contains the prior "cleanup" patch; please don't apply
that one.
Please let me know of any bugs. It is tested reasonably well,
but until I put together random tests it's hard to have 100%
confidence.

[PPC, APFloat] Add full PPCDoubleDouble to APFloat
I have found some internal test failures due to the wrong constant folding
on ppc_fp128.
As documented in APFloat::PPCDoubleDouble, APFloat doesn't support PowerPC
double-double correctly <
https://github.com/llvm-mirror/llvm/blob/492acdd450bcdf9837494d6da029ed064f14fc33/lib/Support/APFloat.cpp#L74
>.
To support this, we need to add a second tuple of (sign, exponent,
significand) to
