X-Git-Tag: elfutils-0.195~60
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ae7d8e1cd9493c07e89d1a6b9c24b23d7cc8d8a;p=thirdparty%2Felfutils.git

elflint, readelf, support SHT_LLVM_LTO and SHT_LLVM_ADDRSIG

An SHT_LLVM_LTO section contains LLVM bitcode. An SHT_LLVM_ADDRSIG
section contains ULEB128 integers referring to the symbol table
indexes of address-significant symbols. This patch just recognizes the
SHT constants but doesn't handle the section contents.

	 * libebl/eblsectiontypename.c (ebl_section_type_name):
	 Recognize SHT_LLVM_ADDRSIG and SHT_LLVM_LTO.
