Description Arjan van de Ven 2005-02-06 17:46:34 UTC

Description of problem:
RHEL4 libgcc.a on ppc64 has a RWE PT_GNU_STACK marking, this results
in the entire distro to run with executable stack markings on ppc64.

Comment 1 Jakub Jelinek 2005-02-09 15:04:45 UTC

This sounds like binutils bug.  On ppc64:
echo '.section .note.GNU-stack,"",@progbits' | as -o a.o -
echo '.section .note.GNU-stack,"",@progbits' | as -o b.o -
ld -r -o c.o [ab].o
readelf -WS [abc].o | grep .note.GNU-stack
  [ 4] .note.GNU-stack   PROGBITS        0000000000000000 000040 000000 00      0
  0  1
  [ 4] .note.GNU-stack   PROGBITS        0000000000000000 000040 000000 00      0
  0  1
  [ 4] .note.GNU-stack   PROGBITS        0000000000000000 000040 000000 00   X  0
  0  1

while on e.g. x86_64 all 3 of them are non-X.
