[llvm-commits] [PATCH] KNRPromotion fix when FLOAT_TYPE_SIZE is not smaller than DOUBLE_TYPE_SIZE

[Mikael Lepistö]

Hi,

I found out that

void function(value)
float value; {}

generated following bitcode

define void @function(double %value1)

In IRC channel this was though to be correct for platforms where 
DOUBLE_TYPE_SIZE is bigger than float size e.g. x86. However in our 
tce-llvm-gcc cross-compiler DOUBLE_TYPE_SIZE is set to be 32 bits as 
FLOAT_TYPE_SIZE. So in this case correct bitcode should have been

define void @function(float %value1)

So here's patch attached for fixing the problem.
