            Bug ID: 28902
           Summary: ld: `not found for insert` error has a weird ordering
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: i at maskray dot me
  Target Milestone: ---

echo 'SECTIONS { .byte : { BYTE(0) } } INSERT AFTER .data;' > insert-data.lds
echo 'SECTIONS { .text : {*(.text)} .data : {*(.data)}}' > a.lds
echo 'SECTIONS { .byte : { BYTE(0) } } INSERT AFTER .note.gnu.build-id;' >
insert-note.lds
echo '.globl _start; _start:; .data; .byte 0' | gcc -c -x assembler - -o a.o
exit

ld.bfd a.o -T insert-data.lds -T a.lds  # ok
ld.bfd a.o -T a.lds -T insert-data.lds  # .data not found for insert

# Remark: The order is puzzling. If ld processes -T in order, one will expect
that `-T a.lds -T insert-data.lds` works and the other order fails.

ld.bfd a.o -T insert-note.lds --build-id  # ok
ld.bfd a.o -T a.lds -T insert-note.lds --build-id  # .note.gnu.build-id not
found for insert
ld.bfd a.o -T a.lds -dT insert-note.lds --build-id  # ok

# Remark: Why -T fails while -dT works is puzzling. If you specify --verbose,
the used linker script is exactly the same.
