From a6963e69b585107132a602718536b5a9af9bb438 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 28 Feb 2003 04:55:04 +0000 Subject: * sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_rela): Remove special case for dl_rtld_map in R_PPC64_RELATIVE; it's harmless to repeat it and avoids the test for the common case. Clean up and fix calculations for TLS relocs. * sysdeps/powerpc/powerpc64/dl-tls.h: Moved to ... * sysdeps/powerpc/dl-tls.h: ... here. (TLS_TP_OFFSET): New macro. * sunrpc/svc_udp.c (svcudp_recv): Add a cast to last change. --- sysdeps/powerpc/dl-tls.h | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 sysdeps/powerpc/dl-tls.h (limited to 'sysdeps/powerpc/dl-tls.h') diff --git a/sysdeps/powerpc/dl-tls.h b/sysdeps/powerpc/dl-tls.h new file mode 100644 index 0000000000..37b96749f8 --- /dev/null +++ b/sysdeps/powerpc/dl-tls.h @@ -0,0 +1,43 @@ +/* Thread-local storage handling in the ELF dynamic linker.
