[LLVMdev] Stupid '-load-vn -licm' question (LLVM 1.6)
Hello! I'm compiling code which uses pointers as iterators. For some
reason--probably a silly misunderstanding of the docs--I can't
eliminate duplicate pointer loads. I'll probably figure this out
eventually, but if somebody else sees the answer instantly, I
certainly won't complain. :-)
Here are the optimizers I'm running:

[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 =

[LLVMdev] Unused malloc/free don't get optimized
Hi, i have some code that allocate some memory, store the pointer to a
variable, read it back and deallocates it, like this:
int %main(int %argc, ubyte** %argv)
{
%c_19 = alloca ubyte*
%malloc_206 = malloc ubyte, uint 10
store ubyte* %malloc_206, ubyte** %c_19
%tmp_207 = load ubyte** %c_19
free ubyte* %tmp_207
ret int 0
}
i expected the optimized to remove everything, but after running it

[LLVMdev] question about GetElementPtr Instruction
You are correct, ubyte 2 simply means 3rd element of the structure. This
quantity is always constant (it specifies the field number), so we could
have used any signed or unsigned integer type for it instead of ubyte.
UByte means 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

[LLVMdev] Problems accessing structs
Hello!
I get some odd behaviour using my structs:
"myKernelMap" = type {int (sbyte*)*, int ()*}
"Kernel" = type {"myKernelMap"*}
The second member ( int()* ) is a pointer to the %getchar() function.
I want to call getchar using this function:

[LLVMdev] Problems with getelementptr
Hello!
I'm having trouble with pointer traversing. I have a design as follows: class -> map -> classFunctions
Starting with a pointer to the class, I want to get a pointer to a classFunction via a pointer to the map.
I can't get that function pointer!
How shall I think to get the traversing right (see code below)? Is it something with the fact that I am using only pointers in my

The section describing the definition of global vars discusses that you

Also, is there another document that describes how you define sections

[LLVMdev] Another question about GetElementPtr Instruction
Hi,
I've another question about getelementptr. So, in the twisted mind of my little
pass, I have a statement like this:
%reg228-mod = getelementptr %struct.SimpleStruct* %N.1, long 0 ; <%struct.SimpleStruct*> [#uses=2]
I'm not sure of the semantics of %a = getelementptr %b, long 0. I want to
think that it is some kind of weird identity (no-op), judging from the operand

Problems saving ff objects
Dear list,
I am trying to understand and use the ff package. As I had some problems saving some ff objects, and as I did not fully manage to understand the whole concept of *.ff, *.ffData and *.RData with the help of the documentation, I tried to reproduce the examples from the help of ffsave.
When I ran, however : (copied from the help)
