Using devel/llvm18 instead got the same.
Looking inside even a /usr/local/llvm19/lib/clang/19/include/
also shows the arm_bf16.h file is not present. By contrast,
for an aarch64 context:
# file /usr/local/llvm19/lib/clang/19/include/arm_bf16.h
/usr/local/llvm19/lib/clang/19/include/arm_bf16.h: C source, ASCII text
Looking quickly at more llvm* shows:
# grep -r arm_bf16 /usr/ports/devel/llvm1*/ | more
=
/usr/ports/devel/llvm11/pkg-plist:%%CLANG%%llvm%%LLVM_SUFFIX%%/lib/clang/%=
%LLVM_RELEASE%%/include/arm_bf16.h
=
/usr/ports/devel/llvm12/pkg-plist:%%CLANG%%llvm%%LLVM_SUFFIX%%/lib/clang/%=
%LLVM_RELEASE%%/include/arm_bf16.h
=
/usr/ports/devel/llvm13/pkg-plist:%%CLANG%%llvm%%LLVM_SUFFIX%%/lib/clang/%=
%LLVM_RELEASE%%/include/arm_bf16.h
/usr/ports/devel/llvm14/Makefile:_BE_INCS_ARM=3D arm_bf16.h =
arm_cde.h arm_fp16.h arm_mve.h arm_neon.h arm_sve.h
/usr/ports/devel/llvm15/Makefile:_BE_INCS_ARM=3D arm_bf16.h =
arm_cde.h arm_fp16.h arm_mve.h arm_neon.h arm_sve.h
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: =
`arm_sve.h` and `arm_bf16.h`, and all those generated files will contain =
a
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: =
`arm_bf16.h` immediately before their own typedef:
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: =
#include <arm_bf16.h>
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: Since =
`arm_bf16.h` is very likely supposed to be the one true place where
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: OS << =
"#include <arm_bf16.h>\n";
/usr/ports/devel/llvm16/files/patch-backport-llvm-db49231: OS << =
"#include <arm_bf16.h>\n";
/usr/ports/devel/llvm16/Makefile:_BE_INCS_ARM=3D arm_bf16.h =
arm_cde.h arm_fp16.h arm_mve.h arm_neon.h arm_sve.h
/usr/ports/devel/llvm17/Makefile:_BE_INCS_AArch64=3D arm_bf16.h =
arm_sme_draft_spec_subject_to_change.h
/usr/ports/devel/llvm18/Makefile:_BE_INCS_AArch64=3D arm_bf16.h
/usr/ports/devel/llvm19/Makefile:_BE_INCS_AArch64=3D arm_bf16.h
llvm1[456] had _BE_INCS_ARM containing arm_bf16.h (and more).
llvm1[789] do not.
I wonder if:
=
https://cgit.freebsd.org/ports/commit/devel/llvm17/Makefile?id=3D778e212f2=
34a825c5e19612df4be2e8f838cb024
doing:
-_BE_INCS_ARM=3D arm_bf16.h arm_cde.h arm_fp16.h arm_mve.h arm_neon.h =
arm_sve.h
+_BE_INCS_ARM=3D arm_cde.h arm_fp16.h arm_mve.h arm_neon.h arm_sve.h
was correct. I'll note that in an armv7 context:
# find /usr/local/*/gcc14/ -name arm_bf16.h -print
=
/usr/local/lib/gcc14/gcc/armv7-portbld-freebsd15.0/14.2.0/include/arm_bf16=
.h
suggesting that gcc14 considers the file as not aarch64 specific but
as armv7 compatibile.
So I've put arm_bf16.h back into the llvm18 test context and sometime
after 3 hrs I should be able to report on a firefox build attempt with
the change (I hope).
