[CC trimmed - excluded Marek]
Too bad Jan,
'configure' works, now. But compilation brakes after that.
How can we add '-cl-no-stdinc' only to CMAKE_CLC_FLAGS and NOT CXX flags
(see below)?
Tried

/opt/llvm-project/libclc/build
libclc/build> cmake ../ -DLLVM_CONFIG=/usr/local/bin/llvm-config
-DCMAKE_LLAsm_FLAGS=-cl-no-stdinc -DCMAKE_CLC_FLAGS=-cl-no-stdinc
and
libclc/build> cmake ../../../llvm-project/libclc/
-DLLVM_CONFIG=/usr/local/bin/llvm-config
-DCMAKE_LLAsm_FLAGS=-cl-no-stdinc

And YES, my time during these 'Corona-Times' is limited, too...
...my wife is a children's nurse, we 5 aktive doctors (4 pneumologist),
7 entire in our family and my second discipline was medicine, too. ;-)
Greetings and Gesundheit

One more update. without changing any cmake files the following
cmdline should work:
cmake ../llvm-project/libclc/
-DLLVM_CONFIG=/usr/local/llvm-git/bin/llvm-config
-DCMAKE_LLAsm_FLAGS=-cl-no-stdinc -DCMAKE_CLC_FLAGS=-cl-no-stdinc

hi,
sorry the option is actually -cl-no-stdinc. you can add it to
'target_compiler_options'.
I should have a patch ready soon(tm), but time is scarce.

Hello Jan,
I very much appreciate your advice.
Tried several places...

Not Marek, but hope this answer will help.
libclc uses clang CLC preprocessor on .ll files, llvm/clang-13
started
including clc declarations by default (clang
cf3ef15a6ec5e5b45c6c54e8fbe3769255e815ce),
thus corrupting any .ll assembly files that are used by libclc.
Inclusion of the default declarations can be turned off using a
cmdline switch but that remains to be implemented in the libclc
build
system.
manually adding '-cl-no-stdinc' should work as a workaround.

Hello Marek,
can't compile anything, here.
Poor Intel Nehalem X3470.
Trying LLVM 12-rc2 later.
