...y.bc" but exits with an > error for "lli -use-mcjit y.bc": > "LLVM ERROR: Unknown object format" When I test the MCJIT under Linux I notice that lli are indeed trying to load a buffer that contains an ELF object but fails to verify the format using RuntimeDyldMachO::isKnownFormat this of course fails since Linux uses ELF instead of Mach-o and this are causing lli to report (unknown object format). We need to implement llvm/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp for the MCJIT to work on ELF systems. Testcase: ./llvm-as < llvm/test/ExecutionEngine/hello.ll |...

Hi Matt, hi Bruno, I am still struggling to use AVX via MCJIT on TOT... did you succeed yet? I seem to be unable to even get lli to run some code with the "use-mcjit" flag. I attached a test case that works fine for "lli y.bc" but exits with an error for "lli -use-mcjit y.bc": "LLVM ERROR: Unknown object format" If I call InitializeAllTargetMCs() before

Following along from lli code, if you add a call to InitializeNativeTargetAsmPrinter() during setup, it gets a bit farther and crashes rather than issuing that error. (Rebuilding with debugging symbols now to dig into it further…) -matt Program received signal EXC_BAD_ACCESS, Could not access memory.
