[Bug 235583] clang error builtin-requires-header on pthread_create on powerpc64
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235583 --- Comment #5 from Alfredo Dal'Ava Júnior --- (In reply to James Clarke from comment #4) I still see other issues regarding conflicting headers during build. For ports devel/llvm*, currently it does have a patch that removes conflicting headers, so it's "fixed". For those using llvm from upstream, I use this as workaround: cd /lib/clang/9.0.0/include/ mkdir bkp mv float.h intrin.h inttypes.h iso646.h limits.h stdalign.h stdarg.h stdatomic.h stdbool.h stddef.h stdint.h stdnoreturn.h tgmath.h unwind.h varargs.h bkp/ -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235583 --- Comment #4 from James Clarke --- (In reply to James Clarke from comment #3) https://reviews.llvm.org/D58531 fixes this for me. It will still warn if the declaration is of the wrong type, but no longer warns if the declaration matches the expected type. This makes it behave like the other builtins declared in system headers. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"

(In reply to David Chisnall from comment #2)
It shows up for users using the system header if they pass -Wsystem-headers,
but otherwise not.
The problem is that *any* declaration of pthread_create will trigger this
warning, since GetBuiltinType will return {} with Error = GE_Missing_type due
to the fact that its type is "" in Builtins.def, and it only works normally
because the warning gets suppressed for system headers. I think the correct
thing to do is to give it the proper type, which I'm working on at the moment
(Clang now has syntax for function types within intrinsic type strings with a
recursive parse call so you can express function pointers; it just also needs
to learn about pthread(_attr)_t).

We have a number of problems because the base system build uses `-Wsystem-headers` and so clang reports a lot of things that it shouldn't, because it treats the system headers as if they aren't system headers. If this is only a problem for the FreeBSD build itself, then I'd recommend against patching the header and instead fix the build system (we add `-Wno-system-headers` elsewhere to work around this). -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
