I'm having a problem of being unable to call into an arbitrary function that is loaded into memory whose pointer address is known to me but was not linked into LLVM. I have added the function and called LLVMAddGlobalMapping with the pointer, and the program segfaults. I was wondering if it is a supported scenario that LLVM can generate a call into an arbitrary function that is not linked. -------------- next part -------------- An HTML attachment was scrubbed...

...) calls to create the types. The assert fails since the optimizer replaces some numbers with a global type. The values are equal but the types are not. I did patch some calls to compare on getTypeID() but got another assert a couple of days later in another source file. I needed 3.7 because of the LLVMAddGlobalMapping C api fixes. Could someone help me out ? Or point me in the right direction? I'm using the C api. -------------- next part -------------- An HTML attachment was scrubbed...

Hello I quite thank you for your advice,but I have to tell that it made no difference too calling "LLVMAddGlobalMapping(ee,LLVMGetNamedFunction(m,"_a_outside_func"),(void*)(&a_outside_func));". 2014-04-04 16:10 GMT+08:00 Anton Korobeynikov <anton at korobeynikov.info>: > Hello > > While there is a symbol in the object file, there is nothing like this > in the final executa...

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* ()*

Hi, I have a IR file generated by Clang: ; ModuleID = 'test_load_lib.c' target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-f80:128:128-v64:64:64-v128:128:128-a0:0:64-f80:32:32-n8:16:32-S32" target triple = "i686-pc-mingw32" declare i32 @a_outside_func(i32) define i32 @test_func() { entry: %call = call i32
