Subject: genattrtab.h (INSN_ALTS_FUNC_NAME): Move it from genautomata.c.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d530b07f81e389fde99a626460ea3b33a34b9a83;p=gcc.git

genattrtab.h (INSN_ALTS_FUNC_NAME): Move it from genautomata.c.

2003-01-20  Vladimir Makarov  <vmakarov@redhat.com>

        * genattrtab.h (INSN_ALTS_FUNC_NAME): Move it from genautomata.c.

	* genautomata.c (INSN_ALTS_FUNC_NAME): Move it into genattrtab.h.

	* genattr.c (main): Output default definition of AUTOMATON_ALTS.
	Wrap up definition `insn_alts'.

	* genattrtab.c (main): Wrap up `insn_alts'.
