Hi, At the code below from ./bindings/ocaml/executionengine/executionengine_ocaml.c, we create an OCaml Variant from C. It is from 2.6, the latest 2.7 has the same code. Line 240 Option = alloc(1, 1) assigns tag1 to the 'some' constructor. In term of http://caml.inria.fr/pub/docs/manual-ocaml/manual032.html, I think the 'some' should have a tag 0. We dont have a runtime error for

Hi David, I'm not certain, but to me the "LLVMSetTarget(module, "i686-apple-darwin11");" line looks suspicious. I'm not familiar with all the ins and outs of how target triples get handled, but it looks to me like that's requesting 32-bit code. I think that if you omit that line completely then the target will be inferred from the execution environment. My best

Hello, [Using LLVM r155315, according to `svn log | head`] I am experimenting with programatically building and jitting functions in a module, and I seem to be coming across a crash in some generated code. Using the llvm-c interface I build up the module which dumps like this: ; ModuleID = 'MyModule' target datalayout = "i686-apple-darwin11" target triple =

Hi, I'm attempting to use MCJIT with the C interface with llvm-3.9.0, and it doesn't seem to work. This code is derived from Paul Smith's example code: int main(int argc, char const* argv[]) { LLVMModuleRef mod = LLVMModuleCreateWithName("my_module"); LLVMTypeRef param_types[] = {LLVMInt32Type(), LLVMInt32Type()}; LLVMTypeRef ret_type =

Thanks for the tip - getting closer: $ ./capi_test 5 6 args[0]: 5 args[1]: 6 result: 4294959200 Here's the code I changed: printf("args[0]: %d\n", (int)LLVMGenericValueToInt(args[0], 0)); printf("args[1]: %d\n", (int)LLVMGenericValueToInt(args[1], 0)); uint64_t (*func)(); func = (uint64_t (*)())LLVMGetFunctionAddress(engine, "sum");

Another quick question. In ./bindings/ocaml/Makefile.ocaml, the configurations when ENABLE_OPTIMIZED<>1 are commented, which set -g flag to $(OCAMLC). Is that for back-compatibility to support OCaml < 3.10.0?

I'm using the llvm-c API and want to use the JIT. I've created the following module ; ModuleID = '_tmp' @a = global i64 5 define i64 @__tempfunc() { entry: %a_val = load i64* @a ret i64 %a_val } This output is generated by LLVMDumpModule just before I call LLVMRunFunction. Which yields a LLVMGenericValueRef. However converting the result to a 64bit integer via

This allows the use of shadow stack from the llvm-c API. I am not sure this is the place to insert the include, though.

Hello, I have a question concerning llvm-c. I have set up a function that needs to invoke an external method, in a other library. It has the following signature: void* NSFullUserName(void); The void* can be replaced with a i8*, that far I was able to get, but when my call is invoked, the engine gives me the following message: LLVM ERROR: Tried to execute an unknown external function: i8* ()*

Unfortunately I was unable to build s390 binaries since multilib was dropped in Fedora 24 on s390x. Going from the source of the 'file' command it seems as if it prints "32-bit" (the architecture is really 31 bit). --- generator/actions.ml | 12 ++++++++++++ src/filearch.c | 10 ++++++++++ test-data/Makefile.am | 2 ++

Hi, Lang. Thanks for clarification. I will check out current branch tomorrow and report you back. Most likely i will create bug issue with cleaned sources for static lib and test ios app. Actually i'm not professional c++ dev so my question is - is there any chance to do the next: 1. compile .cpp code to .ll code (seems i already did it) 2. interpret .ll file by any supported at the moment

Both Clang/LLVM 3.4 -> Clang/LLVM 3.5 And i will also try using MCJIT. 2014-09-17 18:56 GMT+06:00 Anton Smirnov <dev at antonsmirnov.name>: > Hi, Tim. > > I've used Clang 3.4 final release and now i'm going to test it with 3.5 > release (since i've read about arm64 improvements). > I will report my results. > > BTW, is it possible to get smth like

At the moment OpenStack uses kpartx and nbd to resize filesystems and inject files to guests. I sincerely hope they don't allow untrusted users to upload guest images / AMIs :-( To fix this I'm looking into adding libguestfs support as an optional backend in OpenStack. The only missing feature in libguestfs is the ability to call tune2fs on a filesystem. This patch series adds tune2fs

In libguestfs generator we have the concept of optargs which is different from plain arguments. These are mapped to optional arguments in languages that support them such as Python. This commit adds a new concept of optargs. At the moment it is simply limited to handling the optional (in some bindings) flags parameter which is used to handle the NBD_CMD_FLAG_* flags. If present, the old Flags
