128 bit float constant
...nce that's what I need it for)
where a and b are
the top and bottom halves of the 128 bit value,
LLVMValueRef TestConst(LLVMContextRef C, uint64_t a, uint64_t b) {
Type *ty = Type::getFP128Ty(*unwrap(C));
ArrayRef<uint64_t> ar[2] = {a,b};
APInt ai(128,*ar);
APFloat quad(APFloat::IEEEquad(), ai);
return wrap(ConstantFP::get(ty,quad));
}
but for 1.0e0 it returns zero
store fp128 0xL00000000000000000000000000000000, fp128* %e, align 16
and for 1.23e0 returns this, which is wrong. (that repeating 147AE is a bit
weird)
store fp128 0xLE147AE147AE147AE0000000000000000, fp128* %e,...

128 bit float constant
Hi,
Just wondering if it's possible to construct a 128 bit quad precision
floating point
constant without converting the value back to a string.
Cheers Peter

[LLVMdev] numeric limits of llvm Types?
Hi all,
can I access the numeric limits of the llvm types,
e.g. HalfTy, FloatTy, DoubleTy, etc.
in a fashion like the std numeric_limits tool?
std::numeric_limits<half>::min()
std::numeric_limits<half>::max()
In c++API, I want to initialize values and need to know the correct range
for the llvm types....
Thx
Alex

[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.
Neil.
