[LLVMdev] Proposed modification of AsmPrinter::EmitConstantValueOnly()
...This fails in EmitConstantValueOnly() because the GEP arguments are not
recognized as constant (link time) expressions.
It looks to me that a proper solution could be to make
EmitConstantValueOnly() return its constant value and call it for each
argument of the GEP which will then be passed to getIndexedOffset().
Does this sound like a reasonable solution?

[LLVMdev] question about GetElementPtr Instruction
...ans we are limited to at most 256 structure fields but it also makes
the bytecode representation more compact. (To remove this restriction, we
may migrate to UInt in the future and use some kind of Zipf encoding to
avoid increasing bytecode size in the common case.)
There is a routine TargetData::GetIndexedOffset to convert any ptr + index
list to the actual byte offset for a particular target machine. See
llvm/include/Target/TargetData.h.

[LLVMdev] question about GetElementPtr Instruction
I have a question about GetElementPtr.
Suppose I have an GetElementPtr Instruction GI:
%reg = getelementptr %ST* %s, uint 1, ubyte 2, ubyte 1, uint
5, uint 13
I want to check if this is the reference of a component of a
structure, how can I do that? Should I check which operand of
this instruction is 'ubyte' type? How can I do that in code?
should I use
ubyte *a =
