A fairly straightforward replacement, but note that we must rename all variables called ‘regions’ as something else (eg. ‘rs’) because -Wshadow warns about them (which is surprising to me since I thought this warning only applied to local vs global variable, not local variable vs global typedef). Also I got rid of the get_regions accessor method, replacing it everywhere with direct use of re...

hi all, The patch in the attachment add a new pass - region pass to the llvm system. A region pass is similar to a loop pass, all of them execute on a group of BasicBlocks at one time, but it operate on a single entry single exit region, not the nature loop. The original purpose to add such a pass to llvm system is to allow us find out the static control p...

How is the patch compressed? I don't know how to open the file with .7z suffix.

Why not use the "standard" algorithm for detecting SESE-regions and building a program structure tree? It should handle everything you want. It also becomes much simpler to specify a connected SESE-region by entry/exit edges, while a disconnected region is specified by entry/exit blocks. Only defining regions on blocks is not enough to be able to quickly deter...

This was a rather longer trip around the houses than I anticipated! The basic purpose of the patch series is to set $nbdkit_stdio_safe to "0" or "1" in sh and eval plugin scripts. To do that, I ended up adding a nicer way to manipulate environ lists, and to do that, I ended up adding a whole generic vector implementation which is applicable in a lot of different places.

Dear R people, I am having a problem with modeling the following SAS code in R: Class ID Gr Hemi Region Gender Model Y = Gr Region Hemi Gender Gr*Hemi Gr*Region Hemi*Region Gender*Region Gender*Hemi Gr*Hemi*Region Gender*Hemi*Region Gr*Gender*Hemi*Region Random Intercept Region Hemi /Subject = ID (Gr Gender) I.e., ID is a random effect nested in Gr and Gender, leading to ID-specific Intercept, Re...

An evolution of the patch I posted yesterday to qemu-devel (https://www.mail-archive.com/qemu-devel@nongnu.org/msg588920.html) which (a) works and (b) has a test. Rich.
