[cfe-dev] Disabling vectorisation at '-O3'
Yes, it looks like passing ‘EnableVec’ and ‘EnableSLPVec’ to ‘Args.hasFlag’ should be replaced with ‘false’ and then it has the expected behaviour. MartinO From: cfe-dev [mailto:cfe-dev-bounces at lists.llvm.org] On Behalf Of Martin J. O'Riordan via cfe-dev Sent: 01 March 2018 18:02 To...

Inspecting 'Triple' from arbitrary source files
Thanks Tim, Sometimes my hacks last longer than I want as it isn't always apparent how I can implement it properly. At the moment I am looking at changes I need to 'MachineBasicBlock::ReplaceUsesOfBlockWith'. It is most likely that I need to handle the issue in a different way, but the change I need...

Inspecting 'Triple' from arbitrary source files
There's always the hypothetical template<typename T> llvm::Triple giveMeATripleDamnYou(const T &); Just keep adding implementations until you stop needing to. ;-) Cheers. Tim. On 1 January 2018 at 17:00, Martin J. O'Riordan <MartinO at theheart.ie> wrote: > Thanks Tim, > > Sometimes m...

[compiler-rt] '-fprofile-generate' and embedded systems
Yep, done that already, but it is not at all a good fit when the device is inside a drone flying around ;-) What we do have, is a fake file-system that keeps everything in memory, and after the profiling is completed we offload it for analysis. I guess I was hoping that there would be a more robust syste...

Accessing '__attribute__((noinstrument))' during lowering
Thanks David, I have tried ‘MF.getFunction()->hasFnAttribute(Attribute::???)’, but it seems that the front-end ‘NoInstrumentFunction’ attribute is not propagated to the collection of LLVM IR attributes (no equivalent is in the ‘Attribute::AttrKind’ enum). It is not obvious that there is another mechanism, and I suspect that there is no...

Running LNT and the LLVM test-suite on Windows
Is it possible to run the LLVM test-suite using LNT on Windows? Even under Cygwin? If so how can I do this? The Linux instructions use 'virtualenv'. Alternatively, how should I run the LLVM test-suite for a cross-compiler hosted on Windows? Thanks, MartinO ------------...

llvm::cl::opt and enums
I was adding a new option for our backend, and because of the nature of the option I wanted to use an 'enum', something like: enum Direction { left, right, up, down }; cl:opt<Direction> myOpt("option-switch", cl::init(up), cl::desc("what it does"), cl::Hidden);...

Questions about load/store incrementing address modes
Thanks again for your help Steve, I’m thinking perhaps my “SelectADDRrr” pattern is inadequate. The sign-extension is at the hardware level, the code generator sees (should see) it as a 16-bit signed register value. My implementation is just: bool SHAVEISelDAGtoDAG::SelectADDRrr(SDValue &Addr, SDValu...

[cfe-dev] Disabling vectorisation at '-O3'
Please ignore this thread - I got myself confused, the code is fine - too many long days and nights staring at code. There is an issue, but it is different to what I thought. My command line is not: clang -S -O3 -fno-vectorize -fno-slp-vectorize foo.c but: clang -S -fno-vectorize -fno-slp...

Question about changes to 'SelectionDAGISel.h'
Thanks Ahmed and also Alex for your replies. This is more or less what I was realising, but it is a great confidence booster to know that it is the correct way also. I can replace all of my various 'Select*' specialisations with version that use 'ReplaceNode/SelectCode' and return 'void', but w...

Adding comments to 'MachineInstruction'
We'll be doing something similar for our OpenVMS port.  Right now I'm using "AsmStreamer->GetCommentOS()" and writing to the stream at the assembler level but that gets aligned on a right-side column (the column is hardcoded) and you have to be in verbose mode.  So if you come up with somethin...

Running LNT and the LLVM test-suite on Windows
There is no way this will work first try, but there is no reason this cant work with some fixups. We have not been testing it, so im sure there will be glitches. I'd start by running the test-suite with cmake, and see how it goes, then move on to LNT. On September 2, 2016 at 4:18:29 AM, Michael Krus...

[LLVMdev] Specify the default target when configuring LLVM
We have added our own proprietary target to LLVM and up until recently it was configured only for this target. I now build it to include additional targets and this all works fine, I just need to specify the associated triple when compiling and the correct code-generator is selected. But I would like to have it...

Dynamic selection of assembly mnemonic strings
Thanks for the quick answer Bruce. So far as I can tell (from a quick read), this is really for integrated assemblers/disassemblers - but we use an external assembler. When invoking clang we would provide ‘-mcpu=chip_v1’ or ‘-mcpu=chip_v2’, and the mnemonic ‘LD32’ is only valid when compiling for ‘chip_...
