(AB(handle_file)): Don't fail if PF_X | PF_W on architectures known to have executable writable PLT. * sysdeps/powerpc/powerpc32/configure.in (HAVE_PPC_SECURE_PLT): New test. * config.h.in (HAVE_PPC_SECURE_PLT): Add. * malloc/malloc.c (MALLOC_ALIGNMENT): Set to __alignof__ (long double) if long double is more aligned than 2 * SIZE_SZ. (misaligned_chunk): Define. (public_rEALLOc, _int_free, _int_realloc): Use it. --- sysdeps/powerpc/powerpc32/configure.in | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'sysdeps/powerpc/powerpc32/configure.in') diff --git a/sysdeps/powerpc/powerpc32/configure.in b/sysdeps/powerpc/powerpc32/configure.in index 6d2c41cb9a..7219ad993e 100644 --- a/sysdeps/powerpc/powerpc32/configure.in +++ b/sysdeps/powerpc/powerpc32/configure.in @@ -16,3 +16,17 @@ rm -f conftest*]) if test $libc_cv_ppc_rel16 = yes; then AC_DEFINE(HAVE_ASM_PPC_REL16) fi + +# See whether GCC uses -msecure-plt. +AC_CACHE_CHECK(for -msecure-plt by default, libc_cv_ppc_secure_plt, [dnl +echo 'int foo (void) { extern int bar; return bar; }' > conftest.c +libc_cv_ppc_secure_plt=no +if AC_TRY_COMMAND(${CC-cc} -S $CFLAGS conftest.c -fpic -o conftest.s 1>&AS_MESSAGE_LOG_FD); then + if grep '_GLOBAL_OFFSET_TABLE_-.*@ha' conftest.s > /dev/null 2>&1; then + libc_cv_ppc_secure_plt=yes + fi +fi +rm -rf conftest*]) +if test $libc_cv_ppc_secure_plt = yes; then + AC_DEFINE(HAVE_PPC_SECURE_PLT) +fi -- cgit 1.4.1
