[uclibc-ng-devel] [PATCH v2 1/2] ARC: ldso: don't use _DYNAMIC@gotpc construct #1

This converts elf_machine_dynamic() to not use the _DYNAMIC@xx construct which was histroically converted by assembler into _GLOBAL_OFFSET_TABLE Now that "hack" is being removed from assembler, we need to make sure that no code relies on that magic "conversion" Signed-off-by: Vineet Gupta <vgupta(a)synopsys.com> --- ldso/ldso/arc/dl-sysdep.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/ldso/ldso/arc/dl-sysdep.h b/ldso/ldso/arc/dl-sysdep.h index c6086e68e5c6..2b43efde594b 100644 --- a/ldso/ldso/arc/dl-sysdep.h +++ b/ldso/ldso/arc/dl-sysdep.h @@ -119,14 +119,14 @@ extern unsigned __udivmodsi4(unsigned, unsigned) attribute_hidden; | (((type) == R_ARC_COPY) * ELF_RTYPE_CLASS_COPY)) /* - * Get the runtime address of GOT[0] + * Get build time address of .dynamic as setup in GOT[0] + * This is called very early in _dl_start() so it has not been relocated to + * runtime value */ static __always_inline Elf32_Addr elf_machine_dynamic(void) { - Elf32_Addr dyn; - - __asm__("ld %0,[pcl,_DYNAMIC@gotpc]\n\t" : "=r" (dyn)); - return dyn; + extern const Elf32_Addr _GLOBAL_OFFSET_TABLE_[] attribute_hidden; + return _GLOBAL_OFFSET_TABLE_[0]; } /* Return the run-time load address of the shared object. */ -- 2.7.4
