--- Comment #1 from [email protected] ---
Hi Waldemar,
Thanks for the report!
I can reproduce it easily with gcc-10 and gcc-11 but not with gcc-9.
The powerpc 7400 support has been broken since the beginning of gcc-10 development.
After the commit [1] removing -many from the options passed by default to the assembler, the build of this defconfig fail with assembler errors:
arch/powerpc/perf/bhrb.S: Assembler messages:arch/powerpc/perf/bhrb.S:22: Error: unrecognized opcode: cmpldi' arch/powerpc/perf/bhrb.S:24: Error: unrecognized opcode: ld' arch/powerpc/perf/bhrb.S:25: Error: unrecognized opcode: `sldi'
It was fixed later by the commit [2] before the gcc-10 release but glibc segfault at runtime since then.
The Buildroot gitlab-ci testing only test with uClibc-ng libc but I try sometime with Glibc... but I missed this issue.
This issue should be reported to gcc.
