similar to: An internet Forum instead of mailing lists?

Hi David, That’s interesting, because I have a totally different experience. On a forum, every topic gets its own thread, and replies are always there in order for future reference. Topic categories can be defined which encourage subject classification. Advanced searching helps to find already answered questions, prevent duplicates, and enable the continuation of discussions even years later.

Sorry Zach, my apologies. I understood now what you mean. I tried and it works!. But now I found that LLVM_DEBUG statements and other output to the console doesn’t show. How do I get that back?.

Hi Praveen, Thanks for the tip, but Xcode seems to spend all the time running tablegen "custom shell scripts", one by one at a time, not linking. Linking is actually very fast, possibly less than a second. The “scripts” that take longer are “AArch64CommonTableGen" and “AMDGPUCommonTableGen”. As said this is on LLVM 9.0. However, on LLVM 7.0.1, the same process takes just 5-6

If someone can manage it, it wouldn't be a bad thing - obviously open up more parallelism (I don't know how much of LLVM can be built before you hit everything that needs tblgen run - I guess libSupport and some other bits) On Mon, Jul 1, 2019 at 12:54 PM Zakharin, Vyacheslav P via llvm-dev < llvm-dev at lists.llvm.org> wrote: > [resending to the whole list] > > > >

Hey Joan, When looking for build support it is really useful to include a bunch of information about your build up front. Knowing that you are on macOS, and using the Xcode generator are really useful. On macOS, BUILD_SHARED_LIBS won’t really help much because the default linker (ld64) is pretty good. Using an IDE generator and setting LLVM_USE_OPTIMIZED_TABLEGEN will kill your release builds.

I had already adjusted MaxStoresPerMemcpy to my preferred value, and this works great but for the cases where load/stores are used on non-size aligned structs the odd behaviour still happens. For my 3-char, 3-byte struct test, the memcpy replacement appears to consist on a single byte load and store of the last char (this is correct), followed by a 16 bit move of the first two chars, this is also

Hi David, Thank you for your patience but I still don’t get it: I don’t see how that is a “command”, as it’s just a list of strings that state command options. I know how to use the debugger, this is what I attempt to debug: clang --target=msp430 -emit-llvm -c -S -Oz main.c The debugger works fine, but only on the main thread. However breakpoints do not work with the code that was invoked

Much of this has been discussed (over many, many years) on https://bugs.llvm.org/show_bug.cgi?id=28222 Some of the issues that were identified included: 1 - Poor tablegen dependency handling leading to unexpected rebuilds. 2 - Debug STL iterator checks taking an insane amount of time (might be MSVC specific). 3 - Lack of parallelization of custom commands (XCode and VS builds) - VS at least

I need to use ‘createVirtualRegister’ for a specific case in my ‘eliminateFrameIndex’ function implementation. However, whenever that code is executed, I get the assertion "MachineCopyPropagation should be run after register allocation!” at a later stage. I have seen that at least a couple of backend implementations (including ARM Thumb) create virtual registers in ‘eliminatedFrameIndex’.

Hi David, I understand what you say, but have you actually read my messages? I don’t think so, Anyway, I will repost the question in case someone else can help.

This is also the case with the Visual Studio generators. Custom commands in a single cmake file essentially get written out line by line into a single batch file that gets processed as a custom build step. In the VS case this means that it can, for example, run X86 and Aarch64 tablegen steps in parallel with each other but all of the individual X86 invocations get processed serially. I can well

I don’t personally develop on Mac (i use Windows), but I have an analogous setup there where i use ninja to build and Visual Studio for editing, debugging, etc. What i do, and I assume it will be the same or very similar for Xcode, is to run cmake twice, once with Ninja, and once with VS (Xcode for you), from separate directories. I build with the ninja one (“ninja clang” on command line), and I

Hi Praveen, Please, can you elaborate on this?. What do do mean by “building as shared objects”.

That's some good detective work; it definitely explains what you're seeing. Since MSP430 is affected it would probably be pretty easy to upstream an alignment-aware

Hi Eli, Thanks again for your reply. I am unsure about implementing the getCrossCopyRegClass for my target. My target does not support or allow moves to and from the SR. The SR exists because it has implicit involvement in some instructions, but it is opaque to the assembler and to the user as a register. I mean, there are no instructions to directly move or read it, or even access it directly.

FWIW, tablegen does not update timestamps for .inc files, if their contents is unchanged, so if you somehow affect a .td file's timestamp (without changing its contents) it will trigger rebuild of the corresponding .inc file with all subsequent incremental make builds. At the same time, this will not trigger rebuilding any targets dependent on this .inc file, since it is not modified. From
