From b8fcdddcbb192fc367ff04bbd753b9deb69b09f3 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 28 May 2016 18:12:58 +0200 Subject: nios2: sync support with glibc Only static linking is supported for now. More debugging and analyzing for ld.so, TLS and NPTL is required. But at least you can bootup a static root fileystem in Qemu. --- include/elf.h | 97 ++++++++++++++++++++++++++++++----------------------------- 1 file changed, 50 insertions(+), 47 deletions(-) (limited to 'include/elf.h') diff --git a/include/elf.h b/include/elf.h index cca3d3832..e0937b732 100644 --- a/include/elf.h +++ b/include/elf.h @@ -3081,53 +3081,56 @@ typedef Elf32_Addr Elf32_Conflict;
