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

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

Perhaps I am missing some link. Need a bit clarification. For the C language, I want to access the LLVM code immediately generated by llvmgcc(cfrontend/bin/gcc) before it undergoes any further transformation or optimization. 1) Are there any libraries that enable me to parse C code and create the Module instance. 2) If answer to 1) is no, then is there some other way to create Module

I'm CC'ing the llvm-dev list because other people are more knowledgeable about the bytecode format/encoding than I am. Please follow-up the replies to the list.

When I compiled a linux kernel, gccas was used to compile assembly code. But gccas cannot recognize the line comment character "#" of gnu assembler, and abort the compile with reporting a error "syntax error, unexpected $undefined". I watch llvm/tools/gccas, but donot known how to add this function in it. Would you give me some suggestions? Thanks.

Actually, Misha, that won't work. The -C option is used directly in docs/Makefile. So the change will have to go into docs/Makefile. Either that or upgrade install to version 5. Reid.

Hi, When I compile httpd-2.0, llvmgcc reports many struct types and macros undeclared, but gnu-gcc can compile httpd-2.0 completely.

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 Chris, It did compile when I gave that option. But it gives me an error when I try to run the executable on an Intel machine. ----- 1513158 is not prime. Exception handler needed, but not enabled.

Hi all, Any news on the cygwin front? What needs to be done? Can I help? Oleg.

It takes 100% llvm, doesn't it? Or is there some kind of import facility (perhaps as an specially interpreted call or as an extension to llvm which makes
