[LLVMdev] Does the gcc frontend do inlining or deadcode elimination ?
This didn't work as I tried with 197.parser. it works without
"-Wl,-disable-opt" switch though.

I am unsure of whether the LLVM GCC frontend does any inlining.
However, I do know that your methods above run the LLVM inlining pass,
albeit indirectly.

[LLVMdev] Does the gcc frontend do inlining or deadcode elimination ?
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,

[LLVMdev] Can I disable the optimizaiton for llvmgcc?
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

[LLVMdev] Removing inlining of library functions
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

[LLVMdev] pass position
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

[LLVMdev] LLVM Cygwin Run Errors
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...

[LLVMdev] llvm-gcc4 on Debian
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's a bit asymmetric with the previous gcc3 version, isn't it? That
would mean that the "An Example Using the LLVM Tool Chain" section needs
to be updated for the gcc4 frontend.
OTOH, I could

[LLVMdev] llvmc - Compiler Driver - Status Update & Issues
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
