Subject: [PATCH 5/5] Enable static-pie on powerpc64
Date: Mon, 24 Jan 2022 14:36:06 +1030 [thread overview]
Message-ID: <Ye4lrkAX7ED7mq0V@squeak.grove.modra.org> (raw)
In-Reply-To: <Ye1NJQwEpe7AyNYD@squeak.grove.modra.org>
Also regenerate another powerpc configure file that wasn't done when
making the corresponding configure.ac change.
With this series and latest gcc + binutils I get mostly working
static-pie on powerpc64le-linux. There are a number of regressions:
FAIL: elf/tst-glibc-hwcaps-cache
FAIL: elf/tst-glibc-hwcaps-prepend-cache
FAIL: elf/tst-ldconfig-bad-aux-cache
FAIL: elf/tst-ldconfig-ld_so_conf-update
FAIL: elf/tst-tlsifunc-static
* sysdeps/powerpc/powerpc64/configure.ac (SUPPORT_STATIC_PIE): Define.
(PI_STATIC_AND_HIDDEN): Define.
* sysdeps/powerpc/powerpc64/configure: Regenerate.
* sysdeps/unix/sysv/linux/powerpc/configure: Regenerate.
