--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> --- Created attachment 12755 --> https://sourceware.org/bugzilla/attachment.cgi?id=12755&action=edit Patch The change to som.c fix the segmentation fault running objcopy. However, I'm not sure that this isn't just papering over a higher level problem. After this I found we had an extra backslash before the the '$' characters in $DATA$. I revised the get_standard_section_names proc to work around this. After this, the pr23633 started to fail so I xfailed it on som. The reversed-bytes test still doesn't pass. $DATA$ turns into a space. It should be a subspace in $PRIVATE$. The "objcopy object (simple copy)" fails here: tmpdir/bintest.o tmpdir/copy.o differ: char 168, line 1 I believe this is because the 'O' bit gets set in $LIT$ and $MILLICODE$: -bash-4.4$ odump -subspaces tmpdir/bintest.o Subspace dictionary for tmpdir/bintest.o: Sub Sp AC RDCLQIOENKT Key Loc/Init InitLn Start Len Align Fixups Name 0 0 2c ...L0.O.... 24 000001ec 000010 00000000 000010 8 0 4 $CODE$ 1 0 2c ...L0...... 16 000001fc 000000 00000000 000000 8 4 0 $LIT$ 2 0 2c ...L0...... 8 000001fc 000000 00000000 000000 8 4 0 $MILLICODE$ 3 1 1f ...L1...... 24 000001fc 000008 00000000 000008 8 4 1 $DATA$ 4 1 1f ...L1...... 80 00000000 000000 00000000 000000 8 -1 0 $BSS$ -bash-4.4$ odump -subspaces tmpdir/copy.o Subspace dictionary for tmpdir/copy.o: Sub Sp AC RDCLQIOENKT Key Loc/Init InitLn Start Len Align Fixups Name 0 0 2c ...L0.O.... 24 000001ec 000008 00000000 000008 8 0 1 $CODE$ 1 0 2c ...L0.O.... 16 000001f4 000000 00000000 000000 8 -1 0 $LIT$ 2 0 2c ...L0.O.... 8 000001f4 000000 00000000 000000 8 -1 0 $MILLICODE$ 3 1 1f ...L1...... 24 000001f4 000000 00000000 000000 8 -1 0 $DATA$ 4 1 1f ...L1...... 80 00000000 000000 00000000 000000 8 -1 0 $BSS$ The O bit indicates code only (no literal data), so it is incorrectly set by objcopy. There's also differences in fixup indexes and counts. -- You are receiving this mail because: You are on the CC list for the bug.
