Subject: 	* Enable backtracing from inside a SOM shared library back into
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bfaef242b573a6018151f9a8f899fcadcea22203;p=binutils-gdb.git

	* Enable backtracing from inside a SOM shared library back into
	user code.
	* hppa-tdep.c (internalize_unwinds): Accept and use new
	"text_offset" argument for dynamic relocation of
	region_{start,end} fields in the unwind descriptor.
	(read_unwind_info): Pass text_offset to internalize unwinds.
