[ECOS] VSR_TABLE

[ECOS] VSR_TABLE

[Suzuki, RyosIII]

Hello all,

I realized a problem in current CVS sources about SH4.
SH4 is expanded about exception code,  Its vsr_table size is bigger than 
SH3's one.
so I changed the source, "packages/hal/sh/arch/current/src/vectors.S", as 
following.

288c288
<         .long    CYG_LABEL_DEFN(hal_vsr_table)+CYGNUM_HAL_VECTOR_INTERRUPT*4
---
>          .long 
>CYG_LABEL_DEFN(hal_vsr_table)+CYGNUM_HAL_VSR_EXCEPTION_COUNT*4

in orignal source, jump to cyg_hal_default_exception_vsr on SH4 when a 
interrupt is occured.

Thank you,

Yes, but your fix is wrong. Try the below with your platform.

Thank you very much for your help,

Really, how so?  Can you provide any pointers so we could try it?

This is already mentioned at http://sources.redhat.com/ecos/contrib.html
but there are issues with the GPL which means that it cannot be distributed
with eCos.
