https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268196 Bug ID: 268196 Summary: devel/llvm1[2-5]: fix build with clang 15 Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: dim@FreeBSD.org When building llvm12 through llvm15 with clang 15 as host compiler (see bug 265425), and when compiler-rt is enabled, there will be errors due to float= 16 support, similar to: In file included from /wrkdirs/usr/ports/devel/llvm15/work/llvm-project-15.0.6.src/compiler-rt/li= b/builtins/extendhfsf2.c:11: In file included from /wrkdirs/usr/ports/devel/llvm15/work/llvm-project-15.0.6.src/compiler-rt/li= b/builtins/fp_extend_impl.inc:38: =20=20=20 /wrkdirs/usr/ports/devel/llvm15/work/llvm-project-15.0.6.src/compiler-rt/li= b/builtins/fp_extend.h:44:9: error: _Float16 is not supported on this target typedef _Float16 src_t; ^ This is because compiler-rt's CMake infrastructure detects float16 support = at configure time, while targeting 'pure' x86_64, but then builds parts of its tree also targeting i386. To work around this, modify compiler-rt's top-level CMakeLists.txt to move setting the -DCOMPILER_RT_HAS_FLOAT16 compilation flag to the arch-specific= for loop, so it only gets enabled for x86_64, and not for i386. For llvm15, also add another modification that removes the bfloat16 source files from the i386_SOURCES list, so these are not built for i386. --=20 You are receiving this mail because: You are the assignee for the bug.=
