I have written a directdraw program in dx7 that i can get working under wine. I have now written a simple directx8 3d program that works under windows but i am getting these wierd errors under wine. this is the output from wine -debugmsg +module pro666 I think it is a problem with the two libraries d3d8.lib and d3dx8.lib as I can see errors there. Also I notice that these are the two libraries

Hi all, Working on lld aarch64 support I came across an issue where I am not sure which would be best design approach to solve. The aarch64 R_AARCH64_ABS64 relocation for PIC/PIE build requires a dynamic relocation (R_AARCH64_RELATIVE) with the value set as the addend of the relocation. For instance, when linking the crtbeginS.o which contains: Relocation section '.rela.init_array' at

Hello Leslie, I think we are going to need to know a bit more about the ELF ABI for what looks like the ArcCompact before we can help you. LLD's calculation of P (the place to be relocated) is as it is in the generic ELF specification. The Rel.Offset corresponds to the ELF r_offset field. This is covered by: "For a relocatable file, the value is the byte offset from the beginning of the

Hi, I need an advice on implementation of a very specific kind of relocations used by MIPS N64 ABI. As usual the main problem is how to pass target specific data over Native/YAML conversion barrier. In this ABI relocation record r_info field in fact consists of five subfields: * r_sym - symbol index * r_ssym - special symbol * r_type3 - third relocation type * r_type2 - second relocation type

A bit off topic: ARM Group relocations define a logical set of consequent instructions to be relocated to form one single address. For such relocations a 1 to 1 relation is also met, so no need of special processing in applyRelocation. Concerning native format: it also introduced unneeded code complexity to me when I wanted to set calculated relocation addend back into the Reference object in the

Hi Lang, Can you please let me know you think it would be right to modify RuntimeDyldImpl::resolveExternalSymbols to allow resolvers to return 0 addresses? Something like this would be ideal for me: void RuntimeDyldImpl::resolveExternalSymbols() { while (!ExternalSymbolRelocations.empty()) { StringMap<RelocationList>::iterator i = ExternalSymbolRelocations.begin(); StringRef

Hello, I'm working on LLILC (a jit for the CoreCLR built on ORC), in particular, on using LLILC as an ngen jit. I would like to have an ability to be notified of relocations that ObjectLinkingLayer is applying and to be able to tell the linking layer not to resolve certain relocations for external symbols (so that the client can do some custom resolutions later). The only way I found of

Hi Lang, Yes, I can return a non-zero marker value. Are you ok with this version? void RuntimeDyldImpl::resolveExternalSymbols() { while (!ExternalSymbolRelocations.empty()) { StringMap<RelocationList>::iterator i = ExternalSymbolRelocations.begin(); StringRef Name = i->first(); if (Name.size() == 0) { // This is an absolute symbol, use an address of zero.

We can't copy_*_user while holding reservations, that will (soon even for nouveau) lead to deadlocks. And it breaks the cross-driver contract around dma_resv. Fix this by adding a slowpath for when we need relocations, and by pushing the writeback of the new presumed offsets to the very end. Aside from "it compiles" entirely untested unfortunately.

Can we remove Native format support? I'd like to get input from anyone who wants to keep the current Native format in LLD.

Hi, The round trip passes just tries to load a *complete* object file in YAML/Native format back. The internal state should be the complete object file in native/yaml format. If some state is not recorded and that is really needed in the writer, we should add that to the Atom model.

Hi Jim, Yes, the relocation entries have to be reordered so that the got16/lo16 or hi16/lo16 pairs appear consecutively in the relocation table. As a result, relocations can appear in a different order than the instructions that they're for. For example, in this code, the post-RA scheduler inserts an instruction with relocation %got(body_ok) between %got(scope_top) and %lo(scope_top). $ cat
