Hello Daisuke,
Attached is a patch that introduces support for the PPC64 architecture.
The patch was written by Michal Toman (mtoman(a)redhat.com). It is based
upon crash-gcore-command-1.3.0-rc.
The patch supports both big-endian and little-endian formats. However,
it does require the ELF_DATA fix to elf64_fill_elf_header() that I reported
yesterday. I have attached a separate patch to fix elf64_fill_elf_header
and elf32_fill_elf_header().
Please include these two patches in crash-gcore-command-1.3.0.
Thanks,
Dave

Hello Daisuke,
Attached is a patch that introduces support for the PPC64 architecture.
The patch was written by Michal Toman (mtoman(a)redhat.com). It is based
upon crash-gcore-command-1.3.0-rc.
The patch supports both big-endian and little-endian formats. However,
it does require the ELF_DATA fix to elf64_fill_elf_header() that I reported

and elf32_fill_elf_header().

Hi Daisuke,
Can you please replace the add-ppc64-v5.patch with the attached add-ppc64-v6.patch?
The change consists of one line that replaces the (non-existent) "PPC64LE" test
with the __BYTE_ORDER test:
+ifndef ELF_DATA
+#ifdef PPC64LE
+#define ELF_DATA ELFDATA2LSB
+#else
+#define ELF_DATA ELFDATA2MSB
+#endif
+#endif
to this:
+#ifndef ELF_DATA
+#if __BYTE_ORDER == __LITTLE_ENDIAN
+#define ELF_DATA ELFDATA2LSB
+#else
+#define ELF_DATA ELFDATA2MSB
+#endif
+#endif
Actually it's highly unlikely that ELF_DATA will *not* be defined, but
just in case there are distributions where the #include file path does
not pick up /usr/include/asm/elf.h, then the change above will resolve it.
Thanks,
Dave
