Subject: aix: TLS DWARF symbol decorations.
X-Git-Tag: upstream/12.2.0~9070
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=499fa254ae8c9752d8c2cf3130b13ffddfd83546;p=platform%2Fupstream%2Fgcc.git

aix: TLS DWARF symbol decorations.

GCC currently emits TLS relocation decorations on symbols in DWARF sections.
Recent changes to the AIX linker cause it to reject such symbols.
This patch removes the decorations (@ie, @le, @m) and emit only the
qualified symbol name.

gcc/ChangeLog:

	* config/rs6000/rs6000.c (rs6000_output_dwarf_dtprel): Do not add
	XCOFF TLS reloc decorations.
