Compilation fails on 86_64

GoogleCodeExporter commented 8 years ago

Hi,
compilation of r150 fails on
cc1plus: warnings being treated as errors
ocelot/ir/implementation/LLVMInstruction.cpp: In member function 
'std::string ir::LLVMInstruction::Operand::toString() const':
ocelot/ir/implementation/LLVMInstruction.cpp:147: error: dereferencing 
type-punned pointer will break strict-aliasing rules
ocelot/ir/implementation/LLVMInstruction.cpp:206: error: dereferencing 
type-punned pointer will break strict-aliasing rules

Sems that 'classical' solution to this problem is to introduce an union of 
uint32/64 and a float/double. 
Seems that there exists something called std::hexfloat (like std::hex) but 
unfortunately compiler can't find it.

Also 
ocelot/executive/implementation/LLVMExecutableKernel.cpp
fails saying that std::exp is undefined, removing std:: fixed it.

We really need an automated regression system for ocelot.  Right now I am 
developing
on a mix of x86 and x86_64 platforms and bugs do not always manifest themselves 
on
both.  

Anyways, this should be fixed now as of r151, let me know if you have any more 
problems.
