...t's actually what happened and am confused and concerned. My commit was "[DebugInfo] Allow spill slots in call site parameter descriptions", and it appears in the history under two hashes: 1ee84e and 67c416. The first commit contains the actual change. The second touches something in yaml2obj, which I promise I did not do: ``` $ g show 67c416dc9a5aeda034d46bdcb3b63fffa462d28e commit 67c416dc9a5aeda034d46bdcb3b63fffa462d28e Author: Vedant Kumar <vsk at apple.com> Date: Thu Nov 14 09:20:58 2019 [DebugInfo] Allow spill slots in call site parameter descriptions [snip]...

Hi there, I'm proposing for the GSoC project: Add DWARF support to yaml2obj[1]. I've uploaded my proposal. If you have any suggestion or ideas, feel free to leave a comment[2]. Thanks! ------ [1] https://llvm.org/OpenProjects.html#llvm_dwarf_yaml2obj [2] https://docs.google.com/document/d/1miCuMQEX8WZ9_hWXWQtOYTA4JAK-yDnPV9vyO_d5vzE/edit?usp=sharing -- Best Regards,...

I am adding -D k=v to yaml2obj, similar to clang -D. This makes it easy to generate {32-bit,64-bit} x {big-endian,little-endian} tests. --- !ELF FileHeader: Class: ELFCLASS[[BITS]] Data: ELFDATA2[[ENCODE]] Type: ET_DYN Machine: EM_X86_64 # RUN: yaml2obj -D BITS=32 -D ENCODE=LSB %s -o %t.32le #...

?The idea itself is indeed good. Regarding to escaping: I think we should have it. Imagine the following example (I've took it from D73828). --- !ELF FileHeader: Class: ELFCLASS[[BITS]] Data: ELFDATA2LSB Type: ET_EXEC Machine: EM_386 # RUN: yaml2obj %s --docnum=4 -D BITS=32 -o %t-32bit.o # RUN: yaml2obj %s --docnum=4 -D BITS=64 -o %t-64bit.o Without escaping it would be: Class: ELFCLASSBITS What does not look so clear as a version with escaping IMO.

...ld you recommend that I do what is done in unittest/ObjectYAML/MinidumpYAMLTest.cpp which just uses a string inside the source file, or use an Inputs directory? Both are not great, as you point out about using an Inputs directory. Also, I'm not sure that I can create an object without invoking yaml2obj itself, I can't seem to find a function to do this exposed by libObjectYAML. If I do need to invoke yaml2obj, would you happen to know how to tell CMake to build yaml2obj first, and also where would I find that executable? Thanks so much, James.

Spoiler: the following only applies to Windows binary format handling. Potential for extending yaml2obj to support COFF debug directories<https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#debug-directory-image-only> recently came up during a code review<https://reviews.llvm.org/D70606#1873185>.

Hi, As far as I understand now it is impossible to generate ELF object file with relocation sections using yaml2obj tool. I plan to support ELF relocations in the yaml2obj. Does anybody work on it already or plan to start this task soon? -- Simon Atanasyan

Sphinx warns that yaml2obj isn't included into any toctree. Where is a logical place to link this? --Sean Silva

Ideally, I'd have a mode where I can just Do we think that yaml2obj is the best format for this, or would high-level DWARF DIE assembler directives be a more useful abstraction level?

Now the yaml2obj and obj2yaml utilities used in LLVM and LLD projects tests only and not installed by the "make install" command. I think they might be also useful in third-party projects like MCLinker. I suggest to move these utilities into the "tools" category and install them together with ot...

Let's suppose that MCLinker folks are here already - I am a committer of this project :). Maybe I did not formulate my suggestion correctly. When I offer to "install" the yaml2obj and obj2yaml utilities I mean result of the "make install" command only. I do not suggest to include this utilities into any distributed binary packages. To be clear I attached the patch with suggested changes. On Mon, Jul 28, 2014 at 3:07 AM, Sean Silva <chisophugis at gmail.com>...
