I'm probably missing something obvious here, but naively, this makes it kind of awkward to have mutable thread local state... -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20141212/53b577ae/attachment.html>

Howdy, I'm working on writing a dependence analyzer (rather like what LoopDependenceAnalysis wants to be, except a bit more general). While this is a problem of many parts, I'm currently focusing on finding pairs of memory references to test for dependence. Consider this contrived C code: double test2(int n, double *restrict A, double *restrict B, bool flag) { if (flag) { A[0] =

...y() && "Uses remain when a value is destroyed!"' failed. As a separate but probably related detail, the function 'invoke foo' is not being inserted in the foo2 IR. The foo2 invoke generation looks like this: llvm::Module* module = Compiler::Services::SymbolResolver::getInstance()->resolveOrCreateModule( buildParameters.getLLVMContext() , buildParameters.getModuleDefinition() ); HAssertMsg( 0 != module , " null module "); llvm::Module* excptModule = Compiler::Services::SymbolResolver::getInstance()->resolveOrC...

Sorry, I admit my e-mail was a bit unclear. Here is an example: declare void @foo() define void @f(i32* noalias %p) { store i32 1, i32* %p; <-- This is dead call void @foo() store i32 2, i32 *%p ret void } When run through ./llvm-as test.ll -o - | ./opt -O3 -S the dead store is not removed by the DSE pass. (The call to @foo is there to prevent InstCombine

Hello! I am trying to retrieve all instructions from a function's body that are dependent on a specific argument. The strategy I am currently using for that is to follow all uses of the argument and record them. Also, whenever I encounter a store of a dependent value, I try to find loads in the function that are dependent on that store and resume use-tracking from there. For this purpose I am

I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/ but this deals with filling out forms.

Hello, Sorry for my stupid mistakes. I hope that everything is fine now. This patch fixes PR2218. There are no loads in example, however "instcombine" changes memcpy() into store/load.
