...9;ve been doing is for each function taking all the instruction and going through each of their operands (and the opreands of their operands etc...) and checking to see if any are an instance of UnaryConstantExpr. When I encounter such an instance, I determine whether the type of that value and its 0th operand differ, if they do its an implicit cast. I do basically the same procedure for the the global variables. Is this the best approach to take or is there a better way of going about this? I've asked at least a few questions on this mailing-list and you have all been VERY helpful. Thank yo...

Hi, I would like to get the coefficients of x^0, x^1, x^2, . , x^6 from expansion of (1+x+x^2)^3. The result should be 1, 3, 6, 7, 6, 3, 1; How can I calculate in R? You help will be greatly appreciated. Peter [[alternative HTML version deleted]]

...d get rid of those annoying subtractions of FirstVirtualRegister all over the virtual-register-handling passes. Since 0 is used all over the place as "invalid register" it is probably best to leave this alone, let FirstVirtualRegister be 1, and simply ignore (i.e. treat as erroneous) the 0th element of anything keyed off FirstVirtualRegister.

Hi all, It looks like the induction variable simplification pass prefers doing a zero-extension to compute the wider trip count of loops when extending the IV. This can sometimes result in loss of information making ScalarEvolution's analysis conservative which can lead to missed performance opportunities. For example, consider this loopnest- int i, j; for(i=0; i< 40; i++) for(j=0;

Hello, I'm trying to permute a vector of positive integers > 0 with the constraint that each element must be <= twice the element before it (i.e. for some vector x, x[i] <= 2*x[i-1]), assuming the "0th" element is 1. Hence the first element of the vector must always be 1 or 2 (by assuming the "0th" element is 1). Similarly, the 2nd must always be below/= 4, the 3rd always below/= 6, etc. Here's an example, suppose I have the vector x x <- 2:6 This vector already fits the...

Fixed in r123137. I decided to move the virtual register numbers because there is so much code already using physical register numbers as direct indices. My first attempt was to let the virtuals run from -1 downwards, but it turns out that we h...

I would then pattern match the load nodes with: [(set i24:$val, (load addr:$addr))] Where addr is a complex pattern. This is fine for the 0th element in the struct, as there is no offset so the resultant assembly would be (which works fine): r0 = *(i0) The issue I have is with the second load. I need the result to be: m0 = 4 r1 = *(i0 += m0) (offset is stored in a register(m0), and modifies the original pointer) rather than r1 = *(i...

...s actually helpful and I think I now better understand what is going on here. Unless there is a pointer involved, DSA will not collapse nodes. That makes sense... What we would like to leverage DSA for is essentially type-unsafe memory accesses, such as the example where code write a byte into the 0th byte of an integer. Another example would be where a short is written over an integer. Or an integer is written starting from the 2nd byte of another integer. And so on... Now, after I read your answer below, it seems that DSA could still provide us with such conservative information - for each DS...

Yes, Reid. I have used these methods to figure out the layout. Now my question is to build a map between the original layout and the new layout. I show one example below. When LLVM IR access the 4th (starting from 0th) member (i32) of the class A, the map will tell that in fact it is accessing the originally 3rd member (i1). Any suggestion?

I configure the system of remote boot. Almost all was done. But one simple problem. tftp doesn't download pxelinux.0 from boot-server, in.tftpd is running at. Problem isn't in pxelinux.0, but in protocol itself. I've created test file "test" in /tftpboot and tried to download it but "Timeout occured".

Any DWARF compile-unit or type-unit that uses the array (that is, any unit that uses any of the "strx" forms) has a DW_AT_str_offsets_base attribute that points to the 0th element of the array. The producer chooses whether to have one contribution shared by all units, one contribution per unit, or somewhere in between. There's an implication for how to read the .debug_str_offsets section, which is that the reader has to parse the section before using it to look...
