[BZ #14341] * elf/dynamic-link.h (elf_machine_lazy_rel): Properly handle the case when there is a gap between DT_REL and DT_JMPREL sections. * sysdeps/x86_64/Makefile (tests): Add tst-split-dynreloc. (LDFLAGS-tst-split-dynreloc): New. (tst-split-dynreloc-ENV): Likewise. * sysdeps/x86_64/tst-split-dynreloc.c: New file. * sysdeps/x86_64/tst-split-dynreloc.lds: Likewise. --- sysdeps/x86_64/tst-split-dynreloc.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 sysdeps/x86_64/tst-split-dynreloc.c (limited to 'sysdeps/x86_64/tst-split-dynreloc.c') diff --git a/sysdeps/x86_64/tst-split-dynreloc.c b/sysdeps/x86_64/tst-split-dynreloc.c new file mode 100644 index 0000000000..2f9e9b9477 --- /dev/null +++ b/sysdeps/x86_64/tst-split-dynreloc.c @@ -0,0 +1,28 @@ +/* This test will be used to create an executable with a specific + section layout in which .rela.dyn and .rela.plt are not contiguous. + For x86 case, readelf will report something like: + + ... + [10] .rela.dyn RELA + [11] .bar PROGBITS + [12] .rela.plt RELA + ... + + This is important as this case was not correctly handled by dynamic + linker in the bind-now case, and the second section was never + processed. */ + +#include + +const int __attribute__ ((section(".bar"))) bar = 0x12345678; +static const char foo[] = "foo"; + +static int +do_test (void) +{ + printf ("%s %d\n", foo, bar); + return 0; +} + +#define TEST_FUNCTION do_test () +#include "../test-skeleton.c" -- cgit v1.2.3
