search for: funcb

Suppose I have a function funcA() in package pkgA that requires function funcB() from another package pkgB under certain circumstances. Those circumstances are rare though, so I put package pkgB under 'Suggests', and use this in funcA() when those circumstances do arise: if (require("pkgB", quietly=TRUE)) { pkgB::funcB(...) } else { stop("Please...

Dear experts, I am learning llvm by reading documents and have a question to ask. The following is the example of code generation that I created. [[a [10.00]] > [3.00]] ; ModuleID = 'ExprF' define i1 @expr(double* %record) { entry: %0 = getelementptr double* %record, i32 0 ; <double*> [#uses=1] %1 = load double* %0 ; <double>

...guments from the regmask (According to the calling convention). IPRA and CC updated RegMask can’t use the same mechanism because they contradict each other. I think that the following analog will help to explain why I think that a reuse is redundant: Let’s assume two different functions (FuncA and FuncB) need to allocate an array of items of type X. FuncA allocates XarrayA that contains all X items that are big. FuncB allocates XarrayB that contains all X items that are square shaped. Should both of them use the same array?! I think that they shouldn’t. Same in our case. It is true that both stru...

...h other. Can you clarify in which way to they contradict each other? Do you have a patch I could look at? (Or could point at some piece of code in LLVM?) I think that the following analog will help to explain why I think that a reuse is redundant: Let’s assume two different functions (FuncA and FuncB) need to allocate an array of items of type X. FuncA allocates XarrayA that contains all X items that are big. FuncB allocates XarrayB that contains all X items that are square shaped. Should both of them use the same array?! They may not use the same array, but they’ll both use malloc() :-) — Me...

Hi Mehdi, It is true that both IPRA and the proposed mechanism save RegMasks. So you might say that the data structure in the immutable pass should be reused, but this is the only similarity. Even this similarity is not exactly true. I save register masks that doesn’t use passed/returned arguments while IPRA saves register masks for modified registers. So how can they share the same mechanism?
