Changing a header file somewhere and having to spend 10 minutes waiting for a build leads to a lot of wasted developer time. The real culprit here is tablegen. Can we split support and ADT into two - the parts that tablegen depends on and the parts that it doesn't? >From what I can gather, Tablegen currently depends on these headers and all of their transitive dependencies. #include

It would be better, because a debug tablegen is slower than an optimized tablegen, but it's still slow and it doesn't address the problem that tablegen runs *at all* when it doesn't really need to. I think if tablegen wasn't running all the time we could incremental builds down from 15 minutes (and that's on my really powerful machine) to under 5, which seemed like a big

Looks correct. Can you post the output of libFuzzer here? Something like #0 READ cov: 0 bits: 0 units: 97701 exec/s: 0 #1 pulse cov: 732 bits: 0 units: 97701 exec/s: 0 #2 pulse cov: 737 bits: 0 units: 97701 exec/s: 1 #4 pulse cov: 858 bits: 0 units: 97701 exec/s: 2 #8 pulse cov: 880 bits: 0 units: 97701 exec/s: 4 On Thu, Sep 3, 2015 at 10:50 AM, Greg Stark

It's that TableGen depends on Support, so if you change one file in support, support gets recompiled into a new static archive, which triggers a rerun of tablegen on all the tablegen inputs, which is extremely slow.

I thought we already did write tablegen output to temporary files like X86GenAsmWriter1.inc.tmp first and then diffed them with the real .inc file and conditionally copied. ~Craig On Sat, May 27, 2017 at 11:02 AM, David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > > > On Fri, May 26, 2017 at 8:06 PM Zachary Turner via llvm-dev < > llvm-dev at

In my experience the buildsystem works fine in combination with tablegen (at least this aspect of it). The real problem here is that tablegen is just slow. Some of the X86 tables take indeed Last time I looked at it tablegen had still room to optimize the way it resolves class hierarchies and the variables within which it did basically one at a time, so it needed to traverse the hierarchies

I am trying to upgrade my code to use the latest version of llvm from svn. Whenever I include "llvm/ADT/HashExtras.h", I get error messages like the following. Does anyone know what is going on?

Hi, I'm trying to build llvm (git monorepo) on Ubuntu 18.04 with EXPENSIVE_CHECKS enabled and running into various errors compiling SourceMgr.cpp, depending on which host compiler I use. For example with GCC: $ CC=gcc-8 CXX=g++-8 cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON ~/git/llvm-project/llvm/ && ninja ... [89/2690] Building CXX object

Hmm. What about the errors I quoted from using clang-7 (starting about a third of the way down my email, sorry if they got kinda lost in all the noise)? Thanks, Jay.

I just ran into this today. Do we need to update our requirements on libstdc++ version? Jay, did you figure out a way around this?

Hi, I would like to propose, based on a previous discussion on llvm-dev, the following change. https://reviews.llvm.org/D56337 The main motivation for annotating member functions of ADT clases with LLVM_ALWAYS_INLINE was that of speeding up `check-llvm` at `-O0`. Turns out this significantly degrades the debuggability of fundamental classes in llvm itself, e.g. StringRef or SmallVector. After
