Subject: Migrating from gcc-3.3 to gcc-4.2
Date: Thu, 14 Aug 2008 05:09:00 -0000	[thread overview]
Message-ID: <48A3B053.1080208@redpinesignals.com> (raw)

Hi All,

I want to upgrade our gcc cross compiler from gcc-3.3 to gcc-4.2.
I have made direct attempt but I got following error messages .

 error: attempt to use poisoned "TARGET_SWITCHES"
 error: attempt to use poisoned "DEFAULT_SHORT_ENUMS"
 error: attempt to use poisoned "SMALL_STACK"
 error: attempt to use poisoned "FUNCTION_ARG_PASS_BY_REFERENCE"
 error: attempt to use poisoned "MUST_PASS_IN_STACK"
 error: attempt to use poisoned "FUNCTION_ARG_PARTIAL_NREGS"
 error: attempt to use poisoned "EXPAND_BUILTIN_VA_ARG"
 error: attempt to use poisoned "TARGET_MEM_FUNCTIONS"
 error: attempt to use poisoned "CONST_COSTS"
 error: attempt to use poisoned "RTX_COSTS"
 error: attempt to use poisoned "ADDRESS_COST"
 error: attempt to use poisoned "PROMOTE_PROTOTYPES"
 error: attempt to use poisoned "INIT_TARGET_OPTABS"

I think all these macro's are deprecated in gcc-4.2.
Can any body suggest me how to find an  equivalent macro's in gcc.4.2.
Is there any specific documents available to upgrade from gcc-3.3 to 
gcc-4.2 ?

Thanks,
 Siva
