Since _dl_tlsdesc_dynamic is called via PLT, we need to add 8 bytes for push in the PLT entry to align the stack. [BZ #20309] * configure.ac (have-mtls-dialect-gnu2): Set to yes if -mtls-dialect=gnu2 works. * configure: Regenerated. * elf/Makefile [have-mtls-dialect-gnu2 = yes] (tests): Add tst-gnu2-tls1. (modules-names): Add tst-gnu2-tls1mod. ($(objpfx)tst-gnu2-tls1): New. (tst-gnu2-tls1mod.so-no-z-defs): Likewise. (CFLAGS-tst-gnu2-tls1mod.c): Likewise. * elf/tst-gnu2-tls1.c: New file. * elf/tst-gnu2-tls1mod.c: Likewise. * sysdeps/x86_64/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Add 8 bytes for push in the PLT entry to align the stack.
