Question: How hard should tblgen try to fit constants into a particular type? My case is an xor with i8 immediate where I'm using 0xff in as the immediate value. 0xff should fit into i8 if treated as unsigned, but CodeGenDAGPatterns.cpp assumes that any and all integers less than 32-bits are signed. Should tblgen try to see if the sign-extended version of the constant could fit into the type, and failing that, try the unsigned version: Index: utils/TableGen/CodeGenDAGPatterns.cpp =============================================...

...rew? FWIW gcc-4.2 shows the same error as 3.3.5 (see below). Here is a backtrace (courtesy of Andrew) of the tblgen run, which aborts about 50% of the time when it feels like it: #1 0x04e521a3 in abort () at /usr/src/lib/libc/stdlib/abort.c:68 #2 0x04df29d7 in __assert2 (file=0x3c0018e1 "CodeGenDAGPatterns.cpp", line=934, func=0x3c0020a6 "ApplyTypeConstraints", failedexpr=0x3c002400 "getOperator()->isSubClassOf(\"SDNodeXForm\") && \"Unknown node type!\"") at /usr/src/lib/libc/gen/assert.c:52 #3 0x1c0d0bcd in llvm::TreePatternNode::ApplyTyp...

Hi there, I am a student considering a compiler design based dissertation with llvm. I am having problems building llvm on OpenBSD-current. I hope to make a port of llvm for OpenBSD once I have figured out how to build it.

Are you talking about the type checking done in CodeGenDAGPatterns.cpp? Is it easy to post an example? At 11/18/2020 01:55 PM, Thomas Lively wrote: >Hi Paul, > >I think this would be time well spent. At least in the WebAssembly backend, the vast majority of our ISel work is still done with DAG ISel. I know this is different from the performance work you...

Given that I'm only somewhat up-to-speed on the DAG ISel scheme and not much at all on the Global ISel scheme, I'm tempted to work on the former and then the latter. So I'll look at the CodeGenDAGPatterns messages first. Then I will take a look at Global ISel. Matt: Can you suggest one or two things about Global ISel that could use some work? I won't get to it quickly, but it will give me something to focus on. At 11/18/2020 04:17 PM, Thomas Lively wrote: >Yes, the CodeGenDAGPatterns is ex...

Hello. I would like to create a new backend for tablegen that produces code in an generic assembly language (not for a real processor). The documentation page for this says "ToDo", but I think what I want to do is something similar to CodeGenDAGPatterns::ParseInstructions() in CodeGenDAGPatterns.cpp. Is this even vaguely correct? Any pointers would be appreciated. I'm specifically interested in translating X86 into this other language, but getting other processors for free in the process would be great. -- Durward McDonell durward.mcdonell...
