Can anyone shed some light on the origins of the comments... /* Mach-O doesn't support omitting the frame pointer for now. */ ...in gcc/config/i386/i386.c. FSF gcc trunk has enabled the omit-frame-pointer option as the default for both i386 and x86_64 recently. * config.gcc: Handle --enable-frame-pointer. * configure.ac: Add --enable-frame-pointer. * configure: Regenerated. *

My GDB Testsuite runs have been failing more tests, and now an internal test has started failing on some missing dwarf 3 records. Changing compile flags to emit dwarf 2 didn't help. In the past there has been some effort to pass GDB Testsuite, including Dwarf 2 backwards compatibility. What is the plan/mechanism for maintaining Dwarf 2/3 compatibility? -- Rick Foos Qualcomm Innovation

Hi there, I try to install Lotus Notes 7.01 via Wine0.9.19 on Suse 10.0. I can put all the setup items on Lotus Notes and login to my mailbox, but after 30 seconds Notes crash. This is the output what I see in console: fixme:uniscribe:ScriptRecordDigitSubstitution 1024,0x621341ec fixme:ole:CoRegisterMessageFilter message filter has been registered, but will not be used

The error we are getting is: "Undefined Form Value: 25" We have customers that have a variety of debuggers, and we need to be able to preserve Dwarf3 compatibility. GDB, Lauterbach, etc. The patch that caused a problem for us is: https://llvm.org/viewvc/llvm-project/llvm/trunk/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp?r1=162493&r2=162526&pathrev=162526&diff_format=h

Hello I've been looking at a debuginfo issue on an out-of-tree target which uses DWARF aranges. The problem is that aranges are generated for both data and code objects, and the debugger gets confused when program addresses overlap data addresses. The target is a Harvard Architecture CPU, so the appearance of overlapping address ranges is not in itself a bug as they reside in different

Because R_X86_64_32 elements are 4-byte addresses and can't be relocated for the 64-bit address space over 32-bit limit. Dwarf2 actually allows for

We cannot use bitcast because bitcast is a value preserving operation, but the address space conversion operation we have is a bit-changing operation. Where will the bulk of work be? Can we make a ConstantExpr which has a new Opcode (or reuse call) and a list of operands? The first operand is a string.

The particular case we are looking at is converting a pointer from one address space to another address space. There is one operand and one output, both are the same pointer type, except for their address space. The pointers are of the same size. The operation is a bit-changing operation. We are using intrinsic functions for the instructions. We need a solution for the ConstantExpr. Instead of

Hi all, Need your help. I added some debug information to my code according to Kaleidoscope-9 sample and got stuck with a GDB error: (gdb) info functions > invalid dwarf2 offset 1849950870 > My module is a DLL built with llc+ld toolchain. Target triple: 'i686-w64-mingw32'. Looking this offset (1849950870 == 0x6e440296) in dwarfdump output of the dll gave the following:

So, based on the info that I got from Devang, I was able to solve the problem with the duplicate assembly symbols, although I still don't quite understand why it was generating erroneous metadata in the first place. For example, through trial and error I discovered that the problem disappeared if I passed my DICompileUnit to CreateLocation() rather than my DISubprogram, but I don't know

I am looking for a way to allow ConstantExpr to express target specific operations, which will be used in global initializers. The recommended way to extend LLVM IR is using intrinsic functions. But this does not work for ConstantExpr, which the global initializer uses. Should we make ConstantExpr to support some kind of side-effect free intrinsic function calls? If we want to work on such a

HI! On one qemu-kvm instance a kernel update failed and booting the image is not possible anymore (see below). A dozen other VMs are correctly working after the upgrade. Anything I can quickly try to make it work again? (This is not really a bad emergency case because I could simply re-install and re-configure with ansible. But I'd like to learn about these cases...) Ciao, Michael. Loading

Hello, I can't use Wine from version >=0.9.18 anymore. It compiles ok and then it crashes somewhere in the middle of installation, I think when Wine tries to execute something. Even when I try to run winecfg it crashes. It worked with Wine version 0.9.17 and lower. Anyone have any idea what's wrong ? I'm running Slackware 10.0. Below is what happens when I try to run winecfg.

That's an interesting idea. What are the essential differences between the new subclass and ConstantExpr? Will it end up like ConstantExpr? Or you want it to be ConstantExpr 'done right'? Thanks.
