Subject: 	* som.c (som_object_setup): Handle exec_entry and exec_flags being
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0b4aa626512b2d255470691273fd2cc93d22b35;p=binutils-gdb.git

	* som.c (som_object_setup): Handle exec_entry and exec_flags being
	switched in executables created by the OSF1 linker.
	(som_write_fixups): Handle R_EXIT just like the R_{F,L,R}SEL
	fixups.  Support R_ALT_ENTRY (handle just like R_EXIT).
