Manage too add to  llvm/clang5  support for QNX650. I don't know what I,m doing, but it managed to compile ( still using
 QNX linker though) our softwares and passing all of the tests !!!  Which surprised me.

I was hopping for faster build time than gcc 4.8.3 but so far they are very similar.

If anyone is interested to play with it I could post patches I guess. It's surprisingly, well to me at least, how little
 changes it took.  Should be very simple to  get it to work for QNX660 / QNX700. 

Only clang/clang++ is working, no libcxx no linker, sanitizer, etc, that seems more complicated.

ntox86-gdb has no problem debugging clang generated exe.

Hi Mario,

Could you share the patches for clang?

Re: CLANG QNX650

Attached are the diff from todays clang trunk (7.0)

What I have not been able to build yet is libcxx

I used this cmake command to setup the project ( using Ninja )

cmake 	-G"Ninja" \
	-DLLVM_TARGETS_TO_BUILD=X86 \
	-DCMAKE_BUILD_TYPE=Release \
	-DLLVM_DEFAULT_TARGET_TRIPLE=i386-pc-qnx650-gnu \
	-DCOMPILER_RT_INCLUDE_TESTS=OFF \
	-DLLVM_ENABLE_ASSERTIONS=OFF \
	-DLLVM_ENABLE_LTO=ON \
	-DLLVM_ENABLE_ZLIB=ON \
	-DLLVM_BUILD_TEST=OFF \
	-DLLVM_INCLUDE_TESTS=OFF \
	-DLLVM_USE_LINKER=gold \
	-DLLVM_ENABLE_WARNINGS=OFF \
	../trunk

Re: CLANG QNX650

Thanks! It looks fairly easy. I would need this for clang (llvm actually) 5.0. I suppose the effort is similar to this 
one?
