Subject: Re: [PATCH] arch/powerpc: Remove .interp section in vmlinux
Date: Mon, 13 Oct 2025 09:31:48 +0530 [thread overview]
Message-ID: <20251013040148.560439-1-vishalc@linux.ibm.com> (raw)
In-Reply-To: <eeaf8fd6628a75d19872ab31cf7e7179e2baef5e.1751366959.git.christophe.leroy@csgroup.eu>
While debugging a ppc64le QEMU guest on an x86_64 host, I observed GDB crashes
when attempting to attach to the remote target:
(gdb) target remote :1234
Investigation revealed that cross-compiling the Linux kernel for ppc64le on an
x86_64 host using Clang produces a vmlinux binary containing an empty .interp
section. This empty .interp section is responsible for the GDB crashes.
This issue does not occur when:
- Building for ppc64le target using GCC on x86_64 host
- Building for ppc64le target using Clang on ppc64le host
- Building for ppc64le target using GCC on ppc64le host
