Subject: [XTENSA] Hookize OUTPUT_ADDR_CONST_EXTRA
Date: Thu, 06 Jan 2011 06:49:48 -0000

Hello.

  This patch removes obsolete OUTPUT_ADDR_CONST_EXTRA macro from XTENSA back 
end in the GCC and introduces equivalent TARGET_ASM_OUTPUT_ADDR_CONST_EXTRA 
target hook.

  Not tested.

  OK to install?

        * config/xtensa/xtensa.h (OUTPUT_ADDR_CONST_EXTRA): Remove.
        * config/xtensa/xtensa-protos.h (xtensa_output_addr_const_extra): Remove.
        * config/xtensa/xtensa.c (xtensa_output_addr_const_extra): Make static.
        (TARGET_ASM_OUTPUT_ADDR_CONST_EXTRA): Define.



Anatoly.
