This didn't work as I tried with 197.parser. it works without "-Wl,-disable-opt" switch though.

I am investigating some inlining issue, so I did llvm-gcc aaa.c bbb.c ... nnn.c -o output opt -inline -inline-threshold=xxx < output.bc | llc -march=c > output_inline.c 1) I noticed that even if I set xxx to 0 or even a very small negative number, many functions are eliminated. I am wondering if these functions are inlined by the frontend, or identified as deadcode. For instance,

Hi all LLVMor, I just tried to compile a simple code and analyze the number of the basic blocks. But after compile, what I got, the bytecode is seems to be optimized bytecode. So the information of basic blocks is not what I expected. I want ot use the code as example to see how some of code optimization methods work. However, after compiling file using llvm test.c -o test, bytecode file

I am interested in analyzing the bytecode code produced for C files. By default, inlining of user and library functions (libc) is done. If I turn off inlining (-disable-inlining in gccas and gccld) then no inlining is done. I want to be able to inline user code but disallow library code to be inlined. In trying to understand the InlineSimple.cpp code, I see that library functions are

Suppose, I have a Pass1 implemented as a subclass of Pass, with source code in the directory of llvm source base( transform/analyze ) I can run that pass through opt on the bytecode emitted by gcc frontend through opt tool. However, I want that Pass1 to be the part of the actual GCC compiler. I want to know how I can position Pass1 among other passes /optimizations/ code generations. e.g if

Hi, I am wondering whether the bytecode generated by my llvm-gcc is correct? When I run $ llvm-gcc hello.c -o hello What I get is hello.exe.bc, and hello.exe (I can actually llvm-dis the bytecode file which is hello.exe.bc). However, I do not get a shell script(named hello) as stated in the documentation... Best Regards, Kiat On 5/25/05, Aaron Gray <angray at beeb.net> wrote: >

I know that Al Stone has compiled llvm-gcc4 successfully and I can report the same. The problem I consistently run into is that llvm-gcc ends up producing native format output; it does not produce bytecode, nor does it invoke gccas or gccld. I'm using the latest svn, and my configure args are: --prefix=/work/scottm/llvm-cfrontend/obj/../i686-pc-linux-gnu \

That would mean that the "An Example Using the LLVM Tool Chain" section needs to be updated for the gcc4 frontend. OTOH, I could

Hi there, I'm trying to build llvm under cygwin running under windows xp, and have struck the following problem: -- llvm: tools-only built ok -- cfrontend: built ok -- llvm: full build failed at the following point: make[3]: Entering directory `/cygdrive/d/3rd-party/llvm/runtime/GCCLibraries/crtend' Compiling crtend.c to bytecode Compiling listend.ll to bytecode Linking comp_main.bc

Folks, As of the writing of this note, the llvmc tool is enabled for build on the CVS head. I'm encouraging you to try it out, provide some feedback, and help with the issues below. llvmc is now able to correctly link a pure bytecode version of any Stacker program. This includes translation with stkrc, optimization with opt and linking with llvm-link. It is also able to find Stacker's
