This trips up a couple of tests. --- Evening, This is a re-roll of the following patch series: https://inbox.sourceware.org/libc-alpha/20230302112519.914641-1-arsen@gentoo.org/ Changes from v1: - Dropped -z norelro. This turned out to be unnecessary after Adhemervals removal of --with-default-link and linker script machinery: https://patchwork.sourceware.org/project/glibc/list/?series=17843 See: https://inbox.sourceware.org/libc-alpha/86fsakz5mr.fsf@gentoo.org for an explanation of what caused the need for norelro. That fix was misguided, due to a previous error on my part, too. I applied this patch on top of that patchset and it would appear to resolve all related failures. The above is not applied to Git yet, but should be before this patch is. elf/Makefile | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/elf/Makefile b/elf/Makefile index 0d19964d42..4d0e04b2a2 100644 --- a/elf/Makefile +++ b/elf/Makefile @@ -1190,6 +1190,11 @@ postclean-generated += $(objpfx)/dso-sort-tests-2.generated-makefile \ ifeq (yes,$(have-tunables)) $(eval $(call include_dsosort_tests,dso-sort-tests-1.def)) $(eval $(call include_dsosort_tests,dso-sort-tests-2.def)) + +# BZ15311 is intentionally underlinked. +LDFLAGS-tst-bz15311-b.so += -Wl,-z,lazy +LDFLAGS-tst-bz15311-c.so += -Wl,-z,lazy +LDFLAGS-tst-bz15311-d.so += -Wl,-z,lazy endif check-abi: $(objpfx)check-abi-ld.out \ @@ -1514,6 +1519,20 @@ LDFLAGS-tst-initorderb2.so = -Wl,--no-as-needed LDFLAGS-tst-tlsmod5.so = -nostdlib -Wl,--no-as-needed LDFLAGS-tst-tlsmod6.so = -nostdlib -Wl,--no-as-needed +# The following tests are underlinked, and rely on late loading.
