[LLVMdev] 2.5 Pre-release1 available for testing
Hi Tanya, I see the following warnings when building. I'm not sure how to fix any of them. The last one looks like it might be serious (seems like a job for Chris). llvm[1]: Compiling Path.cpp for Release build In file included from Path.cpp:270: Unix/Path.inc: In member function ‘bool llvm::sys::Path::eraseFromDisk(bool, std::string*) const’: Unix/Path.inc:661: warning: ignoring return

-Wmisleading-indentation violations
Hi, I was building LLVM with gcc 6.1.1 recently and it was spitting out some warnings relating to misleading indention that caught my eye. This wasn't a fresh build so I may have missed some. I've CC'ed the authors of the potentially misleading lines so they can decide what do about the warnings (if anything). I'm wondering if clang-format is making some inappropriate choices

Potential ambiguity in the grammar of LLVM IR assembly
Hello Tim, Thank you for getting back to me. The language grammar as defined by the LLVM Language Reference Manual [1] does not include the details of the LLVM IR parser reference implementation. The following extract from "lib/AsmParser/LLParser.cpp" illustrates that unnamed globals are allowed [2]. > /// ParseUnnamedGlobal: > /// OptionalVisibility (ALIAS | IFUNC) ...

[LLVMdev] Fast-math flags in constant expressions
Hi, I'm wondering why lib/AsmParser/LLParser handles fast-math flags in the following IR: ... %val = fmul nnan double 1.0, 1.0 ... but doesn't allow any flags if "fmul" is inside "phi": ... %val = phi double [ fmul (double 1.0, double 1.0), %cond.true ], [ fmul (double 1.0, double 1.0), %cond.false ] ...

Question about versioning of LVVM IR
Hello, It is likely that I missing something however I have to ask. We are working on Mull project https://github.com/mull-project which deals with LLVM IR in the first place so it is often that we encounter errors like the following one when we do things like parseAssemblyString(IR, Err, GlobalCtx);`: ``` test: <string>:7237:187: error: invalid field 'variable' !1526 = distinct

Scalable Vector Types in IR - Next Steps?
Hi Alex, We've only recently managed to get the core scalable vector IR type into the codebase (so it will be present in 9.0); that allows you to write IR with scalable vector types, but there's no backend able to generate code for it yet, and as you mention no support for stepvector (or vscale). Arm will start upstreaming those soon. -Graham > On 13 Jul 2019, at 14:32, Alex Susu via

Is extern_weak a legal linkage for function definitions?
Hi, The LLVM language reference doesn't say that extern_weak is illegal for function definitions, but it seems this restriction is enforced in the code in some places: https://github.com/llvm-mirror/llvm/blob/master/lib/AsmParser/LLParser.cpp#L4591 https://github.com/llvm-mirror/llvm/blob/master/lib/CodeGen/AsmPrinter/AsmPrinter.cpp#L327 However it is possible to create a bitcode file

[LLVMdev] Fast-math flags in constant expressions
Out of curiosity, how would you envision fast-math flags interacting with constant expressions? Off the top of my head, I can’t think of any flags that would be relevant if the expression can just be constant-folded away at full precision anyways. > On Nov 28, 2014, at 4:56 AM, Sergey Dmitrouk <sdmitrouk at accesssoftek.com> wrote: > > Doesn't look like a bug, more like a

[PATCH] D12923: Add support for function attribute "notail"
+llvm-dev Can you give a bit of background on what you're trying to address here? After reading through the discussion and seeing that this is a best effort flag, I'm not sure that a function attribute is the best way to describe this. I'm open to being convinced it is, but I'd like to hear a bit more about the use case and get broader visibility on the proposal first.

[LLVMdev] Bug in Language Reference? %0 versus %1 as starting index.
(gah, this turned into a huge digression, sorry) The implicit numbering of BB's seems to be a pretty frequent issue for people. Surprisingly, the issue boils down to simply changing the IR asm (.ll file) syntax so that it can have "unnamed BB's" in a recognizable way that fits in with how unnamed values work (the asmprinter makes an effort to print a comment with the BB number,

[LLVMdev] Bug in Language Reference? %0 versus %1 as starting index.
Thanks for the lecture :) But I was not planning on changing a single line in LLVM/Clang. I stick to the documentation until I've learned to swim, perhaps even forever. Ah, now I see. You thought I meant "should I modify the code to do this or that." I only meant to change the documentation. Please refer to the patch I've sent on LLVM-commits. That's about what I had

[LLVMdev] First-class debug info IR: MDLocation
I've attached a preliminary patch for `MDLocation` as a follow-up to the RFC [1] last week. It's not commit-ready -- in particular, it squashes a bunch of commits together and doesn't pass `make check` -- but I think it's close enough to indicate the direction and work toward consensus.

[LLVMdev] Metadata for Argument, BasicBlock
If we were to implement the #unroll pragma, we would want to add metadata to loop headers. But, it's not a big deal since we can simply add this metadata to block terminators. -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Dan Gohman Sent: Tuesday, May 08, 2012 00:58 To: Ralf Karrenberg Cc: llvmdev at cs.uiuc.edu List
