Hi, I found that machine dead code elimination, does not respect the calling convention of alpha and eliminates r16, which was set correctly during code generation. I verified it with -print-after-all. Does anybody have a patch for this?

Hi, Can people suggest how this is solved for other ISAs? This happens only for Alpha and not for x86-64. The register 16 does not have any uses within that function, but is used inside puts. So Machine DCE thinks it is dead code. On Wed, Jun 29, 2011 at 4:20 PM, Ankit Sethia <asethia at eecs.umich.edu>wrote: > Hi, > > I found that machine dead code elimination, does not respect

Hi, I configure llvm to generate code for alpha. I use a the following steps to generate code from the source files: 1) llvm-gcc -c main.c -emit-llvm main.bc 2) opt -load <library fo myPass> -myPass main.bc main.opt.bc 3) llc -march=alpha main.opt.bc -o main.S 4) alphaev67-unknown-linux-gnu-as main.S -o main.o Most of the files that i compile run just fine. Suddenly, i have hit on a file

Hi All, I am trying to understand how a back-end generates code for a function that has variable number of arguments. I would also to like to know what changes do i have to do to the corresponding ISAs InstrInfo.td when a call to such a function is made? Any pointers or documentation in this regard is greatly appreciated. -- Ankit -------------- next part -------------- An HTML attachment

Hi All, I changed the CFG of a big function using a pass that runs on a function, I am having trouble debugging it. Is there someway to dump a module to a file from inside gdb?

Hello LLVM community, I was trying to port a target specific loop transformation pass (HexagonVectorLoopCarriedReusePass) to the New Pass Manager. However, I could not figure out a way to register this pass with opt. I can see that llvm/lib/Passes/PassRegistry.def is the registry for target independent passes. Can anyone point me to an example/API which can help me in registering this pass so

Hi, all: Now I'm working on writing a backend for Moto MCore, but I don't know how to describe some instructions. First, I've already written MCoreRegisterInfo.td like these: class MCoreReg<bits<4> num, string name> : Register<name> { let Namespace = "MCore"; field bits<4> Num = num; } def R0 : MCoreReg< 0, "R0">,

Hi all, I installed xapian smoothly as per the guidelines mentioned in the HACKING file. However, I am getting test errors on tests related to python3 bindings after running them using `make check` on this fresh installation. The log can be seen here <http://pastebin.com/bnsTFG2e>. Can anyone here help me out to figure out why they are failing? Please let me know if any more

Guys, I would like to instrument the bytecode that LLVM produces with assertions. I have written the instrumentation code manually, but I do not know how to halt the program in case the assertion is false. I took a look into the bytecode that LLVM produces for a program like: #include <stdlib.h> int main() { exit(1); } And it is like this: define i32 @main() nounwind { entry:

All, I should have chimed in earlier, but have been working on two more side-channel variants of this conversation. At the beginning the PNaCl team was strongly pushing for trying to keep platform ABI compatibility on all platforms while taking one portable bitcode stream as input. During the discussions we've had over the past few weeks it became obvious that that is simply not tractable,

Hi Olly, I updated my local repo and built it again, but still getting the error. I took a look at python3/test-suite.log file, but I could not locate the source of test failure. Please find attached the log file with this email. I am available on IRC(nick : ankit_agrawal) if that seems a convenient medium for you to help me out with this issue. Thanks. Regards, Ankit Agrawal,
