Two functions in DwarfDebug, addBlockByrefAddress() and addComplexAddress(), contain this snippet of code: // Decode the original location, and use that as the start of the byref // variable's location. const TargetRegisterInfo *RI = Asm->TM.getRegisterInfo(); unsigned Reg = RI->getDwarfRegNum(Location.getReg(), false);...

Hi all, I have been looking at how to convert by-reference captures into by-copy captures for captured statements and possibly C++ lambdas, and am looking for some feedback on my approach. The motivation for trying to use copy captures is to avoid unnecessary loads that are otherwise required inside the outlined function. This can be important when the outlined function represents the body of a

This behavior is to be ABI complaint when emitting code for your OS. That said, this is not a very good way to do this.

...table assembly code. The problem is that the code generator is not going to create a copy when compiling a call to "f". Some solutions: 1 ) add support structures as argument in LLVM and tell the various codegen how to handle it. Chris says that LLVM should not go this way 2) add a "byref" mark in the pointer argument. The codegen should now copy the struct on the stack or copy it to registers when generating a call. The function codegen stays the same. This is the proposed solution. 3) Have llvm-gcc create a copy before calling the function. That is, compile -----------------...

I was able to supply sufficiently large buffer to the SpeexBits structure and then encode using (code snippet) _speex.speex_bits_reset(byref(self.bits)) for i in range(0, len - self.frameSize, self.frameSize): _speex.speex_encode_int( ... ) N2 = _speex.speex_bits_write( ... ) However, when I receive the encoded chunk at the decoder side, I don't know how large the output buffer should be since the DTX a...

Hi all, I have the same problem. My guess is that when a structure is passed as a parameter, you cast it into an array for optimization reasons (less parameters, less stack space). This is, certainly, a reasonable optimization, but makes inter-procedural static analysis more complex. Is there a way to disable it (my guess is that this should be doable by passing some parameter to llvm-gcc)? If

Hi everybody! I recently started using llvm in a project on inferring additional information about pointers based on their types, casts, etc. The following simple example is giving me a headache :): typedef struct { int a; short b, c; int d, e, f; } foo; void bar(foo f) { short s; s = f.b; } int main(void) { foo p; bar(p); } Because llvm doesn't allow structures and arrays
