Subject: libgcc: aarch64: Do not use .previous after build attributes
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8c51b32041fdffa67d304aebb39259d1017e5857;p=thirdparty%2Fgcc.git

libgcc: aarch64: Do not use .previous after build attributes

.aeabi_subsection selects the current AArch64 build-attribute
subsection, not the current ELF section.  The following .previous
therefore does not return from the build-attribute subsection.  In
aarch64-asm.h it instead switches back to .note.GNU-stack, which was the
previous ELF section after emitting the non-executable stack note.

Remove the .previous from the build-attribute marking path.  Keep it in
the GNU_PROPERTY path, where it matches the explicit switch to
.note.gnu.property.

libgcc/ChangeLog:

	* config/aarch64/aarch64-asm.h (FEATURE_1_AND_MARK): Do not emit
	.previous after AArch64 build attributes.
