FXMDIChild shrinkwrap to content
How can I get a FXMDIChild to shrinkwrap to its content? Here''s what I''m doing now: def create(*) self.height = maxChildHeight + 30 self.width = maxChildWidth + 10 super end This works, but I''m not crazy about manually adjusting for (apparently) frame and title bar sizes. -- vjoel : Joel VanderWerf : path berkeley edu : 510 665 3407

[AArch64] bug in shrink-wrapping
Hi Arnaud, Thanks for following up with that and sorry for the breakage. Couple of comments: MachineLoopInfo *MLI; + RegScavenger *RS; Would it make sense to use a unique_ptr here? That should eliminate the need of having explicit deletes. +; RUN: llc -mtriple=aarch64-linux-gnu -o - %s Add -enable-shrink-wrap=true and a second RUN line with -enable-shrink-wrap=false. Then add check lines

Issue with shrink wrapping
Hello, So, I have this testcase: void f(int n, int x[]) { if (n < 0) return; int a[n]; for (int i = 0; i < n; i++) a[i] = x[n - i - 1]; for (int i = 0; i < n; i++) x[i] = a[i] + 1; } that, compiled with -O1/-Os for AArch64 and X86, generates machine code, which fails to properly restore the stack pointer upon function

[LLVMdev] Shrink Wrapping - RFC and initial implementation
Here is an updated patch for shrink wrapping with: - spills/restores done with stack slot stores/loads - stack adjustment removed - refactoring (but still in need of more) - spill/restore insertion code unified with spill/restore placement code Documentation available here<http://wiki.github.com/jdmdj/llvm-work/shrink-wrapping-work> illustrates shrink

[3.7 Release] Let's fix the release notes!
Dear everyone, The in-progress release notes for 3.7 [1,2] make it look like we didn't do very much over the past six months. Obviously that's not the case at all, so let's get them in shape! If you've been thinking "I should probably add this to the release notes at some point", now is the time :-) I have a list below of changes that might be worth mentioning. I

Current PGO status
Hello David! I have recently started acquaintance with PGO in LLVM/clang and found your e-mail thread: http://lists.llvm.org/pipermail/llvm-dev/2016-May/099395.html . Here you posted a nice list of optimizations that use profiling and of those which could be using but don't. However that thread is about 2 years old. Could you please kindly let me know if there were

Mac OS X installer: missing files fix
I've paraphrased the OS X installer developer's comments: there's a bug in Installer that is preventing the archive from working right. Below is the fix for the problem. First (obviously) run the installer. Since the executables are in the archive.pax.gz file in the installer package, first do a "show package contents" on the package file, then unstuff the enclosed
