Well, I'm out of ideas. Maybe it's time to debug TableGen and figure out why the type inferencing isn't working? Good luck in any case.

...Continued from the other email Removing the defs section We can potentially infer quite a lot of the defs section but it requires both a complicated ruleset and that tblgen spends processing time doing the inferencing. That processing time is potentially significant for large combiners and for that reason we need to be careful not to let inferencing become a burden on tblgen. My main worry here is that it may require analyzing both the match and apply section to fully inference the types and I'd like the tab...

Dear all, I am trying to reproduce the "Percent May Alias" result described in PLDI 07's paper "Making Context-Sensitive Points-to Analysis with Heap Cloning Practical For The Real World" (http://llvm.org/pubs/2007-06-10-PLDI-DSA.html ). However, my "Percent May Alias" for all the benchmarks is much greater, especially "bzip2". The DSA code I use is

If I force it to use v2f32 for my register class, it still fails with: d:\hq\main\sw\appeng\tools\hpc\opencl\compiler\llvm\test\AMDIL>TableGen. exe -gen -dag-isel -I../../include/ test.td > output GPRV2F32:v2f32:$src1 MACRO_DISTANCE_FAST_v2f32: (set GPRF32:f32:$dst, (i ntrinsic_w_chain:f32 84:iPTR, GPRV2F32:v2f32:$src0, GPRV2F32:v2f32:$src1)) TableGen.exe: In

That looks right to me.

The GVN algorithm used in LLVM currently (I'm rewriting it) is the basic hash based RPO algorithm. The new one i'm writing is based on http://dl.acm.org/citation.cfm?id=512536 (see https://github.com/dberlin/llvm-gvn-rewrite) LLVM has different algorithms for both scalar PRE and load PRE. They are basically variants of standard PRE algorithms transformed into SSA, but with some

Yes, definitely. Deployment is an issue which users will need

Hi David, I agree with you that it would be rude to simply clang-format the MIPS backend without coordination with any out-of-tree derivatives. To be honest, it hadn't occurred to me that there would be any such derivatives and the possibility wasn't raised in our internal discussion before we brought the subject up on this list. I'm keen to coordinate with such derivatives to

Hi, I''m a PHP developer and I''m think about migration to rails... my big problem is about printing web Reports, well I could not found a good thing to help me with this... Does Ror or some other ruby project have some thing to help about make/print database reports? tks
