similar to: [LLVMdev] hazard recognizers for scheduling on x86?

I am working on a target which has some structural hazards. To detect these hazards, I implemented a sub-class of PostRAHazardRecognizer. PostRAHazardRecognizer resets the hazard state on a basic block basis. So, how to detect hazards that may occur between the end of a basic block and the beginning of another basic block ?

Hi, I've developed editor prototype for TableGen files (td). It is Eclipse plugin based on IMP project (The IDE Meta-Tooling Platform). Editor has outline, folding, coloring, go to definition, etc. As any prototype, editor has some limitations (e.g. no cross-file indexing). If there is any interest to such tool I will improve it a bit and then publish. Also considering llvm asm (ll) editing

Hi, Is there anyone else interested in fixed-point arithmetic support in clang/llvm?

Ooops, you are right. Just forgot to CC the mailing list.

Hello Sergey, I'd be interested in such a plugin. At one time somebody else started a plugin to cause Eclipse to compile with LLVM-GCC but I hadn't heard anything else from them. I've been just modifying the commands manually for that. I have definitely not heard of a .td or .ll syntax highlighter plugin. --Sam ----- Original Message ---- > From: Sergey Yakoushkin

I tried llc with -mcpu=help and it dosn't list Sparc.

Hi, llvm doesn't support -fno-toplevel-reorder option which affects glibc/eglibc for some targets. http://www.llvm.org/bugs/show_bug.cgi?id=6364 >From conversations with gcc and eglibc maintainers, seems option is highly expected and is not going to deprecate. >> 2010/2/23 Ian Lance Taylor <iant at google.com>: >> If option is going to deprecate in gcc in near future as

Hi David, I'm working on source to source transformations and instrumentation. A flag to disable 'va_arg' lowering in LLVM FEs will be very useful. Have you sent your modifications upstream to LLVM? If not, could you please share link to your public repository. Thanks, Sergey Yakoushkin On Mon, Jul 19, 2010 at 11:18 PM, David Meyer <pdox at google.com> wrote: > Neal, >

Hi, I'm working on LLVM based compiler. Editing td, llvm asm files a lot. Is there any plug-in (coloring, open declaration, etc) for Eclipse IDE for these files? If not, is there any interest to such plug-in? Regards, Sergey Y.

I would also be interested in fixed-point arithmetic support in clang/llvm? Is there any movement on this direction since August? Regards, Pedro Malagon -- Pedro Malagon Dpt.

Hi, Target architecture for llc can be specified using -march, -mcpu, -mattr options. Is it possible to override target CPU attributes when using llvm-gcc compiler? Regards, Sergey Y.

I'm building tool-chain for processor without integer MUL. So, I've defined __mulsi3 for integer multiplication (int32). Now I've got a problem with int64 multiplication which is implemented in libgcc2.c. Segfualt due to infinite recursion in i64 soft multiplication (libgcc2, __muldi3). LLVM-GCC (for my target) misoptimizes code if -O2 is passed. It promotes i32 multiplication to

Hi Andy, The thing is that I was trying to build a sched graph in other places than these two standard scheduling passes. For instance, in pre-emit. I would like to reschedule a basic block on my vliw target just before assembly emission. I tried to add SUnits for hazards in an experiment, but this gave very weird errors... even while allocating extra space in SUnits vector. For some function, I
