[LLVMdev] Need Help Understanding Operands in X86 MachineFunctionPass
Dear All,
I'm working on an X86 MachineFunctionPass that adds prefetch
instructions to a function. I have code that adds a "prefetchnta
<constant address>" instruction to x86 32-bit code. What I want to do
is to add a "prefetchnta <constant address>" instruction to x86_64 code.
The code for adding the 32-bit instruction is:

[LLVMdev] Stack trace - clang
Hi,
I am new to LLVM and am trying to modify clang for some work. I tried to
insert an instruction: prefetchnta $100 at the beginning of a function.
I encountered a problem when I tried to debug it with gdb. There was an
assertion failure and printed some information without stack trace. The
process has been finished when it printed the information. I tried to
set a breakpoint at the

SVMREF infinte number of genes
dear all,
I am a student in cs college. I would like to know how to plot infinte
number of genes after using the svm.
the data set i have consists of
x which is a matrix of 39 cancer patients [rows] and 2000 gene names
[colmns]. each cell is the value of the gene for a particular patient.
there are two types of cancer people representedas factor y.
here is the code:

[LLVMdev] [x86] Prefetch intrinsics and prefetchw
Hi,
I am looking at how the PREFETCHW instruction is matched to the IR prefetch intrinsic (and __builtin_prefetch).
Consider this C program:
char foo[100];
int bar(void) {
__builtin_prefetch(foo, 0, 0);
__builtin_prefetch(foo, 0, 1);
__builtin_prefetch(foo, 0, 2);
__builtin_prefetch(foo, 0, 3);
__builtin_prefetch(foo, 1, 0);
__builtin_prefetch(foo, 1, 1);
