The powerpc assembler can generate .PPC.EMB.apuinfo sections in some
|
|
circumstances. These originate, I think, from the old e500 ABI; in
|
|
any case, they are only defined for 32-bit ABIs, and there is a
|
|
significant amount of code in bfd/elf32-ppc.c to handle them
|
|
appropriately, none of which is in elf64-ppc.c. However, the
|
|
assembler can generate them when building 64-bit code for processors
|
|
such as e5500 (which uses PPC_OPCODE_E500MC). In such circumstances,
|
|
they get generated as PROGBITS rather than NOTE sections, which
|
|
reportedly can cause problems in a Linux kernel build.
|
|
|
|
Since these sections are only defined in 32-bit ABIs, I think it's
|
|
most appropriate to avoid generating them for 64-bit output, which
|
|
this patch does.
