PATCH 1/1 kernel: Assembly: need add prefix for h8300 architecture.

Need add related prefix for h8300, or can not pass compiling by the latest linker.

The related error (allmodconfig for h8300):

/usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file usr/initramfs_data.o' is incompatible with h8300h output /usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file kernel/modsign_certificate.o' is incompatible with h8300h output

If this implementation is correct, the implementation still can be improved (at least, it is not quite well to hard code the architecture related code in "kernel/" and "usr/" sub-directory).

But it seems, I have no right to add or move files, so welcome any members help do it.

And welcome any additional suggestions or completions.

Thanks.

After check binutils-2.22 source code, can pass "-no-warn-mismatch" to 'ld' to avoid this error.

I will send patch v2 for it.

Hmm, how about something like:

#ifdef CONFIG_ARCH_ASM_INCBIN_NEEDS_PREFIX
#include <asm/incbin_prefix.h>
ASM_INCBIN_PREFIX
#endif /* ARCH_ASM_INCBIN_NEEDS_PREFIX */

Then h8300 can define ARCH_ASM_INCBIN_NEEDS_PREFIX in Kconfig and define ASM_INCBIN_PREFIX in arch/h8300/include/asm/incbin_prefix.h?

Cheers,
Rusty.

Thank you for your reply firstly, I think your way is OK (valuable to continue think of the details implementation).

And excuse me, I continued replying multiple times for this thread (I am just continue improving it).

Current status:

after check the binutils-2.22 source code, we know if use "-no-warn-mismatch" for 'ld', it can avoid this issue.

and also for another 'ld' issue (which I occurs but not send mail), need use "-accept-unknown-input-arch" for 'ld':
"Relocatable linking with relocations from format elf32-h8300 (firmware/keyspan/mpr.fw.gen.o) to format elf32-h8300 (firmware/built-in.o) is not supported"

... maybe find more issues during compiling with 'allmodconfig'.

My opinion:

if h8300 is still one of important architecture, we need try to "let our binary match 'ld'" else just use skipping parameters is OK.

In my current feeling, h8300 is not one of important architecture, so I choose 2nd.

Welcome additional suggestion or completions.

Thanks.

Thank you for your reply firstly, I think your way is OK (valuable to continue think of the details implementation).

The final result is: we have to use this way (mark 'h8300h' explicitly) to fix this issue. (build-in.o requires "h8300h", but the default value of the ".S" files are "h8300").

"-no-warn-mismatch" and "-accept-unknown-input-arch" have no effect with the same issue under firmware sub-directory (after reading 'ld' code, we know there are additional stricter checking for it).

After let 'h8300' pass allmodconfig, I will send patch v3 (may need some days for waiting gcc issues).

Welcome any additional suggestions or completions (especially for modifying the firmware files, I have no experience for it).

Thanks.

And excuse me, I continued replying multiple times for this thread (I am just continue improving it).
Current status:
after check the binutils-2.22 source code, we know if use "-no-warn-mismatch" for 'ld', it can avoid this issue.
and also for another 'ld' issue (which I occurs but not send mail), need use "-accept-unknown-input-arch" for 'ld':
"Relocatable linking with relocations from format elf32-h8300 (firmware/keyspan/mpr.fw.gen.o) to format elf32-h8300 (firmware/built-in.o) is not supported"
... maybe find more issues during compiling with 'allmodconfig'.
My opinion:
if h8300 is still one of important architecture, we need try to "let our binary match 'ld'" else just use skipping parameters is OK.
In my current feeling, h8300 is not one of important architecture, so I choose 2nd.
Welcome additional suggestion or completions.
Thanks.

Need add related prefix for h8300, or can not pass compiling by the latest linker.
The related error (allmodconfig for h8300):
/usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file usr/initramfs_data.o' is incompatible with h8300h output /usr/local/bin/h8300-gchen-elf-ld: h8300 architecture of input file kernel/modsign_certificate.o' is incompatible with h8300h output
