Hi Michael, Overall patch looks good. I do have a few comments below. My main comment is please try to make the style match that used in the MCMachOStreamer more closely. I intend to refactor more functionality into the base MCObjectStreamer class, and having them use consistent idioms makes this easier; specific instances are included in the comments: -- > diff --git a/lib/MC/WinCOFFStreamer.cpp b/lib/MC/WinCOFFStreamer.cpp > index 1030cdb..07...

Updated patch to work with mainline. http://github.com/Bigcheese/llvm-mirror/commit/d19a4c82c18afc4830c09b70f02d162292231c94 - Michael Spencer

...tive to the ARMAsmBackend class (using handleAssemblerFlag). In the example above we start assembling in arm mode (because of the -triple) and so the ARMAsmBackend always thinks we are in arm mode and it emits the wrong opcode. We actually can assemble this example correctly for darwin because the MCMachOStreamer does pass on the directives. It looks like we need to modify the MCElfStreamer to pass the assembler directives down to the ARMAsmBackend to match the behavior of the MCMachOStreamer. Unfortunately, this change will not solve the full problem, even though the integrated assembler works correctly...

Dear there, I wasn't able to generate obj file for bpf using llc: llc -march bpf -filetype=obj foo.bc Anyone knows what is the missing part in their backend? I want to make it work for my project.

I am having an issue with MCJIT on the ppc64 machine architecture. The symptom is that for a particular IR function the target machine won't emit neither an object nor an assembly file and subsequent calling the pointer to function results in a segfault. My application generates on the fly several functions with the builder and executes them with the MCJIT engine. I came across this
