Hello, Richard > Phase: Optimization > optimize bzip2.ubc to become an LLVM bitcode file What's happening here? Are you running some standard LLVM tool like opt? -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.

Hi, I know my last question was very vague (i.e. "It stopped working, what went wrong?"), so here is a little more concrete example: If I run the optimizer (opt) on this code snippet with -std-compile-opts the optimizer hangs. ; ModuleID = 'test.ubc' target datalayout =

Hi Anton, You're already a part of the llvm development team by participating actively on the llvm development list :) If you wish we can put you on: http://llvm.cs.uiuc.edu/Developers.html Great to have you on the team, welcome! We (Jeff, Morten, Paolo, the rest of the team and I) are looking forward to cooperate with you and to push win32 and mingw versions even further to stable and

How can a frontend tell LLVM to put a function argument on stack/register/etc?

I tried to ask for 32 and that didn't seem to help. MallocInst also seemed to ignore the 16 byte directive. For now, I'm just issuing all my loads as unaligned and that's working ok.

Absolutely.

Chuck, > It is dying trying to store a our working vector into one of the LLVM > vectors created on the stack. Despite the align-16 directive on the > alloca instruction, it is not always aligning to a 16-byte boundary. The stack is not necessary 16 bytes aligned on linux/windows. The vector is really sotred aligned relative to %esp, but %esp value is not good. This is known problem

Interesting, but why in this case stuff like 'force_align_arg_pointer' required? -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.

Nothing... I'll show you all the info related to: The intrinsic: def int_soru_sre : Intrinsic<[llvm_void_ty, llvm_i32_ty], [IntrWriteMem]>; The lower instruction (in MIPS): class SORUI<bits<6> op, dag outs, dag ins, string asmstr, list<dag> pattern, InstrItinClass itin>: FI<op, outs, ins, asmstr, pattern, itin> { let isBarrier = 1; // or call,
