Hi, How does the requirement that phi instructions have one value per predecessor basic block interact with indirectbr instructions? For instance, take the following code: L1: br i1 %somevalue, label %L2, label %L3 L2: %ret1 = i8* blockaddress(@myfunction, %L5) br label %L4 L3: %ret2 = i8* blockaddress(@myfunction, %L6) br label %L4 L4: %ret = phi i8* [%ret1, L2], [%ret2, L3] indirectbr i8* %ret, [label %L5, label %L6] L5: %myval = phi i32 [0, %L2], [1, %L3] ; are both of these values required, even t...

Hello, Semi-new r user here and still learning the ropes. I am creating dummy variables for a dataset on stock prices in r. One dummy variable is called prev1 and is: prev1 <- ifelse(ret1 >= .5, 1, 0) where ret1 is the previous day's return. The variable "prev1" is created fine and works in my regression model and for running conditional statistics. However, when I call the names() function on the dataset the freshly created variable (prev1) doesn't show up; a...

Quick question -- if I have a vector of strings that I'd like to split into two new vectors based on a substring that is inside of each string, what is the most efficient way to do this? The substring that I want to split on is multiple characters, if that matters, and it is contained in every element of the character vector. --j -- Jonathan A. Greenberg, PhD Postdoctoral Scholar

This change refactors guestfs___has_windows_systemroot to guestfs___get_windows_systemroot. The new function returns a dynamically allocated char * which must be freed. The new function is no less efficient than before, as it returns the result of guestfs___case_sensitive_path_silently, which is required anyway. The new code is slightly more efficient than before, as it re-uses the result of this

Hi All, We have recently found some optimization opportunities created by replicating code into branches in order to enable optimization. In general, the optimization opportunity we are pursuing is like the following. Given pseudo-code: // block A if (some condition) // block B // block C If it can be efficiently proven that some portion of block C can be simplified had control flow not
