Hepp! I am sitting in a remote country trying to reboot my server at home. Services are running, but the filesystem seems to be unreachable. I can ssh into the system, but when entering interactive mode, nothing happens and the session is terminated. Then I thought - what if sshd had builtins like bash...

...strs::buildSchedGraph for implicit operands is not correct, simply because changing the order of the operands would already prevent the R600 packetizer from bundling in this example.

...e test-cases from confidential code. If you can write a “verifier" that makes the compiler crash on an assertion then you can use bug point to reduce your test case. You don’t need to actually commit the verifier, just the reduced test case.

Hi, I run into a a strange error when compiling with debug infos, where LLC tries to generate a variable DIE using a completely wrong frame-index (DebugDwarf tries to resolve frame index 27 in a simple function which only has a single frame object .. ). After digging around, I found that MachineModuleInfo has a VariableDbgInfo map, that is filled by SelectionDAGBuilder.

Hepp! ------ It''s been a while since the last ClockingIT - http://www.clockingit.com - release, but the new version has finally been deployed, with quite a few improvements. ClockingIT is now much better at handling a large number of tasks and issues, and it''s a lot easier to see what...

Trying to set up the inventory service on puppet 2.6.8, pretty sure I''ve met all the dependencies but puppetmaster logs Could not autoload inventory_active_record: uninitialized constant ActiveRecord When clients attempt to connect. local gems: *** LOCAL GEMS *** abstract (1.0.0) actionmailer (3.0.7, 2.2.3) actionpack (3.0.7, 2.2.3) activemodel (3.0.7) activerecord (3.0.7)

Hello, I am working on backend development and would like to utilize my target's MCAsmParser inside of an MCInst-level class implementation. I noticed that the AsmParser is registered with the target registry however I am having no luck grepping for a "template" of how to instantiate it and have yet to find specific documentation on how it is done. Any ideas or help is greatly

We are developing a new backend for a custom processor using LLVM. After updating to LLVM 3.2, we run into an assertion in BlockFrequencyImpl.h. The offending test-case looks basically like this: for ( ... ) { switch (i) { case 100: // do something break; case 102: // do something else break; case 103: // do some more break; case 104: // now something different

Hello, The ScheduleDAGInstrs::buildSchedGraph() function creates def/uses lists by iterating over all instruction operands and calls addPhysRegDeps() if used post-RA (line ~770 ff.). If an operand is a def, the uses of that registers are cleared (ScheduleDAGInstrs.cpp:333: Uses.eraseAll(Reg); ). As a consequence, if an instruction has an explicit use of a register and an implicit def of the

Hi, Thanks for your explanations! How is the big picture for supporting in-order VLIW architectures and the like though? I am asking because I am currently implementing instruction scheduling in our own backend for our custom Patmos processor, for which I need to support both branch delay slots and bundles, some restrictions regarding bundles. For the moment, I am quite happy with a simple

Hello! The if-converter tries to match 'Simple' patterns looking like this: // Simple (split, no rejoin): // EBB // | \_ // | | // | TBB---> exit // | // FBB The IfConverter::ValidSimple method (lib/CodeGen/IfConversion.cpp:461) checks if TBB matches this pattern. It basically does this by simply checking if AnalyseBranch fails on

Hi, I am using Eclipse to edit the files, and I used it to debug with gdb as well (but I went back to gdb on the command line, Eclipse GDB UI is just too slow and buggy for me ..). You need to exclude the clang preprocessor/.. stress tests from the sources, otherwise the indexer will freeze Eclipse. You should also remove some autogenerated CMake project subdirectories, otherwise your files
