Replace --enable-static-pie with --disable-default-pie
|
|
|
|
Build glibc programs and tests as PIE by default and enable static-pie
|
|
automatically if the architecture and toolchain supports it.
|
|
|
|
Also add a new configuration option --disable-default-pie to prevent
|
|
building programs as PIE.
|
|
|
|
Only the following architectures now have PIE disabled by default
|
|
because they do not work at the moment. hppa, ia64, alpha and csky
|
|
don't work because the linker is unable to handle a pcrel relocation
|
|
generated from PIE objects. The microblaze compiler is currently
|
|
failing with an ICE. GNU hurd tries to enable static-pie, which does
|
|
not work and hence fails. All these targets have default PIE disabled
|
|
at the moment and I have left it to the target maintainers to enable PIE
|
|
on their targets.
|
|
|
|
build-many-glibcs runs clean for all targets. I also tested x86_64 on
|
|
Fedora and Ubuntu, to verify that the default build as well as
|
|
--disable-default-pie work as expected with both system toolchains.

+executables (PIE). By default, glibc programs and tests are created as
|
|
+position independent executables on targets that support it. If the toolchain
|
|
+and architecture support it, static executables are built as static PIE and the
|
|
+resulting glibc can be used with the GCC option, -static-pie, which is
|
|
+available with GCC 8 or above, to create static PIE.
