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:

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

Hi all, The AsmPrinter class supports functions like EmitInt8, EmitInt16, and EmitInt32 for writing a 1/2/4 byte directive to the assembly. Each of these calls the MCStreamer::EmitIntValue method with the corresponding size. For some reason, there is no EmitInt64, and I was wondering if there was a fundamental reason why? The EmitIntValue function appears to support 8-byte inputs. I...

Hi everyone, vmkit requires to know the size of a jitted method before emitting the method. This allows to allocate the correct size for the method. The attached patch creates this functionality when the flag SizedMemoryCode is on. In order to implement this functionality, i had to virtualize some MachineCodeEmitter functions. Is it OK to commit the patch? Thanks, Nicolas --------------

Hi, I'm building a new backend which can only load very limited range of imm. So I decided to use constant pool, and place constant pool entries close enough to instructions use the entries (we have very limited range PC-relative memory load). However, lld & llc output the object files that gather all constant pool entries into one section. How can I make them mix these entries into code
