onetbb uses illegal instruction on i386: no such instruction: `tpause %ecx' that is not supported when macports is forced to use a non-default gcc compiler and an old assembler to try to build it as a fun experiment

16. S. Pointless to report to upstream, they do not support 32-bit systems.

[reneeotten (Renee Otten)]

well if upstream doesn’t support it what do you want the port maintainer to do here. These type of tickets seem very useless… if it’s something you are interested in, feel free to fix it and submit a PR - no point in opening tickets IMHO.

[kencu (Ken)]

using gcc to build things usually forces the ancient Apple gas assembler which is very outdated.

any current clang should work

​https://github.com/oneapi-src/oneTBB/blob/7340a880885cfec2bf05d981e83e44612d1efb6e/include/oneapi/tbb/detail/_config.h#L338

or you can use the macports cctools mod that uses a newer clang as assembler,

or you can alter the test to disable the tpause functions in tbb instead:

​https://github.com/oneapi-src/oneTBB/blob/7340a880885cfec2bf05d981e83e44612d1efb6e/include/oneapi/tbb/detail/_config.h#L338

Looking at the portfile, I cannot see how this should be building with gcc13 on 10.6 i386 anyway.

[kencu (Ken)]

builds fine on the buildbot with clang-11

Thank you, your suggestion worked to resolve the issue.

16. S. Will any Macports clang assembler work with libstdc++ (for Intel, obviously)?

(On a side note, this is potentially a problematic solution, since some ports will build without errors but produce broken binaries: having assembler recognizing AVX, for example, will not make CoreDuo to support them. GCC at least honestly fails at compile time.)

BTW, judging from this, it will not build with Clang on certain Intel cpus either: ​https://stackoverflow.com/questions/22395292/assembler-messages-no-such-instruction-xbegin Since TSX is not necessarily supported on hardware level: ​https://en.wikipedia.org/wiki/Transactional_Synchronization_Extensions

After disabling __TBB_TSX_INTRINSICS_PRESENT I have OneTBB built.
