[LLVMdev] ELF / COFF Summary
...;t this mean the ELF/COFF interfaces should be at the same
level? I'm looking at the X86/X86CodeEmitter.cpp file and the various
methods for emitting instructions/blocks/addresses/etc. Shouldn't the
ELF/COFF interfaces be somewhat similar?
5. I have libELF building under LLVM. Its in lib/ObjCode/ELF (new).
Should I commit it?
Reid.

Yes, but it requires significant hacking, and the result for 2.6 is a
mostly bitcode kernel with a few userspace shared libraries linked in
as objcode (yes, the kernel builds .so files and includes them in the
binary). There are a few changes here and there you can make to the
kernel code to produce significantly nicer bitcodes too (e.g. rather
than having module level asm that makes symbols weak, you can just
have gcc do it).

...er the target is 32- or
64-bit), anything more complex should be exposed as virtual methods that
are overloaded. The ELF spec makes it very clear what parts of the file
format are common across targets and what the variations are caused by.

What does it do, how is it structured? Can you email out the interface
for feedback? I would suggest lib/CodeGen/ELFWriter or something similar,
since it is effectively a part of the target-independent code generator.

[LLVMdev] compile linux kernel
Hi,
I'm trying to compile linux-2.6.23.16 with llvm-2.3. Is it at all
possible? I get "Not an ELF" error. I pass "-emit-llvm" option to spit
LLVM IR, which can be JITed at runtime
$ make CROSS_COMPILE=llvm- CFLAGS="-O2 -emit-llvm"
Error: not ELF
make[2]: *** [scripts/mod/elfconfig.h] Error 1
make[1]: *** [scripts/mod] Error 2
make: *** [scripts] Error 2
