Trying to find a bug within my program and wondered whether the code is just not supported by LLVM. Let me know if you need a testcase.

Hopefully someone more familiar with the specifics of that will chime in. -Jim On Jun 29, 2012, at 8:58 AM, Verena Beckham <verena at codeplay.com> wrote: > Hi, > > In X86MachObjectWriter::RecordX86Relocation I found the comment > > > if (Target.isAbsolute()) { // constant > // SymbolNum of 0 indicates the absolute section. > // > // FIXME: Currently, these are never g...

...iced a Hexagon test (CodeGen/Hexagon/expand-condsets-rm-reg.mir) has a hack around this by inserting an additional COPY to a register, but that shouldn't be required. It means tests that are generated using llc might be failing because they are wrongly identified as SSA.

hi guys, I am having problems after scaffolding I created a db called "requests" and when i tried to execute the command script/generate scaffold request It gave me an error please make sure you have a database request created before you do this The db is obviously created; rails cant access it... so I tried to hack i copied my view model and controller files from my local deployment to

...ction addModule doesn't do anything useful. You need to create a new ExecutionEngine for each module. I'm working with LLVM 3.1, but I don't think much has changed in trunk.

Hi, You cannot call removeModule on a JIT with no modules: jitstate will be 0 and therefore we have a null-pointer exception. The function returns a boolean for success/failure, however, so you would expect to be able to call it and get false back. Should we be checking for jitstate != 0 before accessing the variable? - if (jitstate->getModule() == M) { + if (jitstate &&

...ead before it. So that read is considered the last use. In my example this leads to a register not being fully renamed everywhere. I don't think a predicated write should count as a define.

...ever, attached a "pseudo mir" which should be easily adaptable for a public target. Maybe this is not a bug, but my function at this stage is not canonical? Also, I am not on tip (though I checked the TailDuplicator tip), so it is possible this is fixed elsewhere.
