Cannot build Flang with latest LLVM

inderjeet_kalra · April 13, 2020, 6:36am

Hi,

I just did an llvm build from source and here’s what I hit. I am trying to build projects “mlir;clang;openmp;flang”.

Steps Followed:

git clone https://github.com/llvm/llvm-project.git
cmake -DLLVM_ENABLE_PROJECTS=“mlir;clang;openmp;flang” -DCMAKE_C_COMPILER=/usr/local/bin/gcc -DCMAKE_CXX_COMPILER=/usr/local/bin/g++ -G “Unix Makefiles” -DLLVM_USE_LINKER=gold -DCMAKE_BUILD_TYPE=Debug …/llvm/
make

[root@localhost build]# /usr/local/bin/g++ -v
Using built-in specs.
COLLECT_GCC=/usr/local/bin/g++
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-pc-linux-gnu/7.3.0/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with: ./configure --disable-multilib --enable-languages=c,c++,fortran

TBH, this looks like a MLIR problem to me as all the errors seem to originate from the MLIR subfolder.

Did you try building without flang? If the error persists we need to notify MLIR folks, if not it might

be our cmake.

Cheers,

Johannes

I stripped some text so the list accepts the message:

mehdi_amini · April 13, 2020, 6:03pm

Can you provide the git hash so that we ensure we are building the same revision?
The problem you mention seems like related to a patch I reverted on Friday.

inderjeet_kalra · April 14, 2020, 1:52am

Hi Mehdi,

I think I downloaded source code on Thursday, I will try build again with latest source code.
Here is my current version where problem is reported:

[WebAssembly] Use dummy debug info in Emscripten SjLj

Summary:
D74269 added debug info to newly created instructions, including calls
to malloc and free, by taking debug info from existing instructions
around, whose debug info may or may not be empty.

But there are cases debug info is required by the IR verifier: when both
the caller and the callee functions have DISubprograms, meaning we
already have declarations to malloc or free with a DISubprogram
attached, newly created calls to malloc and free should have
non-empty debug info. This patch creates a non-empty dummy debug info in
this case to those calls to make the IR verifier pass.
