[Bug ld/10073] R_ARM_THM_PC8 Relocation Not Implemented in elf32-arm.c

[osk at exegin dot com]

Hi Nick,

I tried out the patch, but it doesn't appear to work correctly. GNU ld still
outputs warnings when attempting to link the two libraries. We get the following
warnings:

libecc.a(tk-aes-e.obj): In function `tkAesSetupEnc':
c:\IAR_work\mce_release\src\aes\tk-aes-e.c:(.text+0x98): relocation truncated to
fit: R_ARM_THM_PC8 against `.text_9'
libecc.a(tk-aes-e.obj): In function `aesEnc':
c:\IAR_work\mce_release\src\aes\tk-aes-e.c:(.text+0x416): relocation truncated
to fit: R_ARM_THM_PC8 against `.text_11'

I downloded a copy of the ARM/ELF specification, and it shows that the
R_ARM_THM_PC8 appears to be a special case for computing the initial addend. I'm
not sure if the submitted patch takes this into account.

Thanks,
Owen
