Subject: [PATCH] xtensa.h (MASK_SERIALIZE_VOLATILE, [...]): Delete.
* config/xtensa/xtensa.h (MASK_SERIALIZE_VOLATILE,
TARGET_SERIALIZE_VOLATILE): Delete.
(MASK_CONST16, MASK_ABS, MASK_ADDX): Renumber flag bits.
(TARGET_DEFAULT): Remove MASK_SERIALIZE_VOLATILE.
(TARGET_SWITCHES): Remove "-mserialize-volatile" and
"-mno-serialize-volatile".
* config/xtensa/xtensa.c (print_operand): Remove checks of
TARGET_SERIALIZE_VOLATILE.
* config/xtensa/xtensa.md (*lsiu, *ssiu): Likewise.
* doc/invoke.texi (Option Summary, Xtensa Options): Remove
"-mserialize-volatile" and "-mno-serialize-volatile" options.
