similar to: [LLVMdev] LLVM linkage flags

As mentioned in the Updated ThinLTO RFC ( http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-May/086211.html), I am sending the symbol linkage and renaming required by ThinLTO as a separate RFC. It is included below. I've also attached the doc in pdf form, since the formatting (especially for the table at the end) may not come through in the copied text below well. Thanks! Teresa ThinLTO

Hi Good day. I am facing issue with creating a GlobalVariable. I already have an extern for that global in a header file to use it in the following way extern const void* DATA_TABLE[]; And with a LLVM PASS, I am trying to create this array with the same name and with initializer. So, I have following: GlobalVariable *gvar_data = new GlobalVariable( M, blockItems->getType(), true,

I am programmatically building some functions in intermediate representation, and trying to verify them, but the verifier always reports that there is a problem, and I can't see why. Minimal test case: #ifdef _MSC_VER #pragma warning(disable : 4141) #pragma warning(disable : 4530) #pragma warning(disable : 4624) #endif #include <llvm/IR/IRBuilder.h> #include <llvm/IR/Verifier.h>

What is the difference between WeakAnyLinkage and ExternalWeakLinkage ? They are defined in GlobalValue.h. Thanks Junjie

There is a description of all the possible linkage types at http://llvm.org/docs/LangRef.html#linkage – does this answer your question? (Basically, an extern_weak resp. ExternalWeakLinkage symbol becomes null instead of being an undefined reference) David On 3/16/11 7:06 PM, Junjie Gu wrote: > What is the difference between WeakAnyLinkage and ExternalWeakLinkage > ?

Are there any benchmark resultss that meaningfully compare performance of ext2 vs ext3 vs rieserfs vs sgi xfs? What about effect on cpu usage?

All, If I have source file like this: /**********************************/ #include <stdbool.h> #include <stdio.h> int main(int argc, char* argv[]) { switch(argc == 2) { case true: puts("argc == 2"); break; case false: puts("argc != 2"); break; } return 0; } /**********************************/ When I compile this source file with

You're probably using an old clang. There is an option "-Wno-switch-bool" that turns this warning off, but if your clang does not understand it, there may be no other

Hi, I have a pass that creates a GlobalVariable, when I ran it get the following error: Global is external, but doesn't have external or weak linkage! i8** @myvar This is how I create the GlobalVariable: ------------------------------------------------ new llvm::GlobalVariable(*M, IRB.getInt8PtrTy(), false, llvm::GlobalValue::CommonLinkage, nullptr, "myvar", NULL,

The various ac patches have had ext3 for some time. What is the difference between using Alan's patches vs the ext3 patches?

Something bad must have happened when I first ran e2fstune on my root file system. Now I cannot mount it ext3 and when I try to run tune2fs -j on it, I get this error message: permission denied while trying to create journal file There is a .journal file in /: [root@monster log]# ls -l /.journal -rw------- 1 root root 33554432 Sep 29 10:21 /.journal But dumpe2fs

I have changed it to ExternalLinkage. Now, in LLVM IR, it looks like that: @DATA_TABLE = external global [0 x i8*], section "data_section", align 16 #0 @DATA_TABLE.1 = global [10 x i8*] [i8* inttoptr (i64 53415718 to i8*), i8* bitcast (void (%class.Hello*)* @_ZN5Hello5ptofnEv to i8*),...], section "data_section", align 16 #0 In my uses: %arrayidx = getelementptr inbounds [0 x

I thought I understood things, but I guess not. I recently configured a new system for a colleague as follows: 1. Redhat 7.1 install Dell Inspiron 8100 - three partitions on 30G - /, /boot, swap 2. Boot up 3. configure, make, make install of linux-2.4.12-ac3 (with approriate lilo changes) lilo (but no reboot until 8) 4. rpm -U mount-2.11g-5.i386.rpm (from rawhide)

Hello I am on Athlon 1Gz, kernel 2.4.8. I was running a perl pgm with a lot of disk access, deletions and symlinks creations... Maybe It is due to the kernel version. Could you please inform me if must upgrade to a more recent kernel ? Thanks a lot the kernel logs are : in errors logs Oct 18 17:31:16 tadorne kernel: Assertion failure in journal_revoke_Rb5884a32() at revoke.c:307:

Great! For the hotness, try creating a small test case with a very hot loop that iterates many times. Let me know if you are still having trouble. While the llvm-dis serialization is being discussed, I suppose at the very least this can go in with the rest of the existing YAML summary dumping and get emitted from llvm-lto2 using the patch Peter attached. Peter - do you want to add that to

I noticed that AsmPrinter::EmitLinkage doesn't handle ExternalWeakLinkage. Is that an oversight or is something deeper going on? -Dave
