Could you expand on this a bit? I see from my build directory that llvm-tblgen.exe was built before the Target/* .inc files. It sounds like you're saying that something has to be built between the .exe and the .inc files. At 8/4/2020 02:44 PM, Chris Lattner wrote: >> On Aug 4, 2020, at 11:31 AM, Paul C.

Folks, I am interested in contributing to LLVM in the future. Meanwhile, I am reading many of the project documents (right now, "TableGen Language Reference"). Is there a way I can contribute corrections to these documents without cloning and building LLVM? ~~ Paul ---------------------------------------------------------------- Windfall Paul C.

I understood that the name is a matching tag for the operand and not its name (as in named macro or function arguments). However, I was assuming that the names in any one DAG node had to be unique and so could serve as selectors for operands. But a quick investigation shows that I was wrong: names can be duplicated in the same node. So DAG indexes are integers only. At 10/12/2020 01:46 PM,

Oh yes, I am diffing the output of some of the tests in order to be sure everything is the same. And running the tests, too. I have a question about the release notes. The current version of LLVM is 10. There are release notes for 12. What happened to poor old version 11? At 8/7/2020 02:55 PM, David Blaikie wrote: >On Fri, Aug 7, 2020 at 11:47 AM Paul C.

John, I'm pretty much down to details and smoothing the text. Here is a pdf. Can you mark it with comments? Or you can send an email with a list. I will incorporate your comments and send you a second proof, so you can be sure I understood you.

I was confused by the lack of TableGen backends in the llvm/lib/tablegen directory until I stumbled upon the llvm/utils/tablegen directory.

Well, I was hinting at LLVM_DEBUG messages. You can pretty much dump all "actions" Tablegen would take to process a .td file, which should suffice, IMO. On Wed, Aug 5, 2020 at 5:59 PM Paul C.

I think I could stomach changing the tests over time, although at least one should be left with the old punctuator. It's the "real" .td files that scare me. Tell me more abut diffing the test files. I assume that the CHECK: lines are checking the important results of each .td file, and so if all the tests still pass, things are good. Are you suggesting some way of automating the

This morning I did a build with Ninja, which mysteriously decided to rebuild the entire system (something about a deps stamp being corrupted). When it was done, I had a new llvm-tblgen.exe, but all the target .inc files were old. Hmm. So I touched one of the TableGen source files and did another build. Again, a new llvm-tblgen.exe but no new .inc files. I do, however, have a new .inc.d file

Are all the records collected as they are parsed, with template parameter substitution and lets, and *then*, after all records are collected, a "pass" is made to calculate the inter-field expressions? Once I understand this, I will add a section to the new guide to explain it. I presume it is the case that this behavior should be publicized. It also appears to be the case that a record

I guess I'll have to do some reading because I don't have a good high level understanding of how the build bot works. For gribozavr4 does that mean running a new buildbot slave process on the machine or can slaves build multiple configurations (is this the same as what

Thank you for driving this Paul, I agree that it is better to have one doc on TableGen.

You are correct, sir. Everything works much better if I run CMake and Ninja from a "developer command prompt." I displayed the path and almost fell off my chair laughing. The road to hell is paved with environment variable entries. Two questions. 1. Building with Visual Studio created build/release/bin. Building with Ninja created build/bin (no release directory). Does that make sense?

Hi Paul, If all you care about is debugging then for now we can just emit a few more debug messages which would help to "trace" the flow. To distinguish traces you can prefix it with some known string. I don't think you really need a 'trace' tag in the language spec for this. Debugging Tablegen has always been a nightmare and I don't think we can ever reach a stage where

I hacked around a bit with the simple case of tracing just classes and defs (no multiclasses or defms). Below you will see my test file and then the output produced. Note that the regular output from the PrintRecords backend follows the trace, so you can see the final classes and records there. Once the trace can be selective, it makes sense to add another option for PrintRecords that restricts
