According to https://reviews.llvm.org/D88348#2344466, that diff should fix the failure.

No. A shared object is needed if it is linked in (1)--no-as-needed mode or (2) after --gc-sections, a symbol referenced by a live input section is defined by the shared object. You'll need to check whether a symbol is defined by libmvec.so.1 On Mon, Nov 9, 2020 at 9:57 AM Alexandre Bique <bique.alexandre at gmail.com> wrote: > > On Mon, Nov 9, 2020 at 6:52 PM Fāng-ruì Sòng

I have made some further investigation. My conclusion is that GNU ld does not do better than lld. Making the --defsym behavior ideal is difficult in the current framework. GNU ld has some unintended behaviors. ld.bfd a.o --defsym 'd=foo' --gc-sections -o a => GNU ld retains .text_foo ld.bfd a.o --defsym 'd=foo+3' --gc-sections -o a => GNU ld drops .text_foo ld.bfd a.o

I apologize that my two patches "Remove trailing space" (r338291 in clang, r338293 in llvm) are committed without a discussion happening within the community. Forward to llvm-dev and cfe-dev to see if they are what the community would like to see committed or not.

Sorry, I didn't notice this change of default last night.

Hi everyone, I am fairly new to LLVM, I'm working on a new backend. I am trying to add information to a specific instruction using the .symtab in the ELF format. I've been searching through the LLVM source code trying to find a way to do such a thing. Can anyone help me with some directions or point me to some documents in the matter. Thanks, Liad. -------------- next part --------------

Thank you very much for your help Fāng-ruì Sòng. I've tried various things like linking directly to libm-2.32 but it didn't work, it seems that libm-2.32 still pulls libmvec. I have the following linker flags: CLANG_LDFLAGS="-fuse-ld=lld -static-libstdc++ -static-libgcc -fvisibility=hidden -fdata-sections -ffunction-sections" CLANG_LDFLAGS="$CLANG_LDFLAGS

This is configured in the "pre-merge checks" build plan, the "Hold Drafts" needs to be set to "Never" I should be able to change this in the build plan if you want but I don't want to step on anyone's toes MyDeveloperDay On Tue, Jul 28, 2020 at 1:35 PM MyDeveloper Day <mydeveloperday at gmail.com> wrote: > See the "Draft Mode" changes,

Hi Liad, I'm not an expert in MC, but what you describe doesn't sound any different from how you would handle a branch instruction. Create an MCSymbol that represents the address of the target instruction; use that symbol as an operand in the referencing instruction; emit the symbol as a label just prior to emitting the target instruction. The second and third steps can occur in either

Hi Reid, Thanks for your help! I could detect the problem and the module now can be saved (it was a problem with some Alloca instructions). I could not find a "verify" method in the Module class, but just for the records, I did this: --------------- PassManager Passes; // Add an appropriate TargetData instance for this module... Passes.add(new TargetData("save",

Hello, I am receiving this error: assert(Slot != -1 && "Value in symtab but has no slot number!!"); While trying to generate a module at run time using LLVM classes. Specifically with an instance of StoreInst class. After I generate all the instructions, I try to save the Module to bytecode, but I receive that error in the method 'outputSymbolTable' Does anyone

Hi Ricardo, Yes, its because you have an invalid module. You should run Module::verify before attempting to write the bytecode. This will pinpoint the problem for you. However, I think I know what's going on: you've left an object (a Value not a Type) in the symbol table that is not in the Module. Not quite sure how you do that, but I suppose its possible if you manipulated the symbol

Hey Paul, first of all thank you for taking the time to answer me, if I understand you correctly, I need to modify the instruction it self so one of it's operands is a symbol, and then at MC layer handle that symbol and add an entry to the symtab for that label? What kind of symbol should I use doing such thing? external symbol or MCSymbol? I was trying to find where in the code during the MC

Hi! If there is a string table for section headers, it also gets loaded. Therefore take it into account in size calculation for kernel symtab. Also there is no need to call elf_set_verbose() a second time after elf_init() (First call happens within elf_init()).
