r110124@banpei: zack | 2006-01-22 14:45:55 -0800 * gensupport.c: Define get_insn_name and record_insn_name here. (read_md_rtx): Call record_insn_name as appropriate. * genattr.c, genattrtab.c, gencodes.c, genconfig.c, genemit.c * genextract.c, genflags.c, genopinit.c, genoutput.c, genpeep.c * genpreds.c, genrecog.c: Don't define get_insn_name nor record_insn_name. * Makefile.in (BUILD_SUPPORT, BUILD_PRINT): Fold into BUILD_RTL. (BUILD_VARRAY): Delete. (genprognormal): Rename genprogmd. Fold in all programs from genprognoprint; also attrtab. (build/genattrtab): Just mention genautomata.o and varray.o. Reorganize a bit, add comments to make the categories clearer. From-SVN: r110120
