Fix pr 17276. See the description here: https://sourceware.org/ml/gdb-patches/2014-08/msg00283.html This patch keeps track of whether the current line has seen a non-zero discriminator, and if so coalesces consecutive entries for the same line (by ignoring all entries after the first). gdb/ChangeLog: PR 17276 * dwarf2read.c (dwarf_record_line_p): New function. (dwarf_decode_lines_1): Ignore subsequent line number entries for the same line if any entry had a non-zero discriminator. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-single-line-discriminators.S: New file. * gdb.dwarf2/dw2-single-line-discriminators.c: New file. * gdb.dwarf2/dw2-single-line-discriminators.exp: New file.
