	MELT branch merged with trunk rev 186692 using svnmerge

[gcc/]

2012-04-23  Basile Starynkevitch  <basile@starynkevitch.net>

	{{improvements for merging with GCC 4.8 trunk svn rev 186692}}
	* melt-run.proto.h (MELT_GCC_VERSION): Define, if unknown, in the
	generated melt-run.h

	* melt-runtime.c (melt_val2passflag): TODO_dump_func &
	TODO_dump_cgraph don't exist in GCC 4.8.

	* melt-build.tpl: Say flavor, not variant!  Build first the
	quicklybuilt application modules, to catch error in macro C
	strings...

	* melt-build.mk: Regenerate.

	* melt/warmelt-base.melt (valdesc_strbuf): Check for MELT_GCC_VERSION also.

	* melt/warmelt-genobj.melt (compilobj_nrep_citeration): Use
	meltcit prefix in generated citerator names..

	* melt/warmelt-outobj.melt (syntestgen_citerator): Use
	meltcitstate prefix.

	* melt/xtramelt-ana-base.melt (each_cgraph_fun_body)
	(each_cgraph_fun_entryblock, each_cgraph_fun_call_flow_graph)
	(each_bb_cfun, with_cfun_decl): Adapt to GCC 4.8, add
	documentation.
	(each_cgraph_decl): Only for GCC 4.6 & 4.7
