https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278879 Bug ID: 278879 Summary: LIB32 incompatible with gcc on aarch64 Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: brooks@FreeBSD.org We can't build LIB32 with the aarch64-gcc13 toolchain because the compiler doesn't support 32-bit arm via -m32 the way the amd64 and powerpc64* compilers do. This is due to a mix of GCC's architectural choice to not support multiple architectures in a single build and Arm's decision to divorce the aarch64 backend from prior targets. The easiest solution seems likely to be to add a toolchain wrapper port that installs both aarch64-gcc13 and armv7-gcc13 (or armv6 I guess) and has compiler wrappers that dispatch based on the presence of -m32 in the argument list. Another alternative is to add a mechanism to specify a per-compat-target set of tools and have the compat mechanism use it, but that's going to be a bunch of work and complexity to support a single target with a non-default compiler. -- You are receiving this mail because: You are the assignee for the bug.home | help
