[LLVMdev] Being able to know the jitted code-size before emitting
OK, here's a new patch that adds the infrastructure and the implementation for X86, ARM and PPC of GetInstSize and GetFunctionSize. Both functions are virtual functions defined in TargetInstrInfo.h. For X86, I moved some commodity functions from X86CodeEmitter to X86InstrInfo. What do you think? Nicolas Evan Cheng wrote: > > I think both of these belong to TargetInstrInfo. And

[LLVMdev] Why does the x86-64 JIT emit stubs for external calls?
In X86CodeGen.cpp, the following code appears in the handler used for CALL64pcrel32 instructions: // Assume undefined functions may be outside the Small codespace. bool NeedStub = (Is64BitMode && (TM.getCodeModel() == CodeModel::Large || TM.getSubtarget<X86Subtarget>().isTargetDarwin())) || Opcode == X86::TAILJMPd; emitGlobalAddress(MO.getGlobal(), X86::reloc_pcrel_word, MO.getOffset(), 0, NeedStub);...

[LLVMdev] Exception handling in JIT
Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the

[LLVMdev] Exception handling in JIT
Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:
