From bb0ddc2f1eca652aa8af56825b2ba3182498cc5a Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 2 Mar 2003 11:45:12 +0000 Subject: * sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_fixup_plt): Don't use weak_extern for dl_rtld_map. Instead check only if [SHARED]. (elf_machine_rela): Clean up. * sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela): Clean up. PowerPC TLS support contributed by Paul Mackerras . * sysdeps/powerpc/powerpc32/elf/configure.in: New file. * sysdeps/powerpc/powerpc32/elf/configure: New generated file. * elf/tls-macros.h [__powerpc__ && !__powerpc64__] (TLS_LE, TLS_IE, TLS_LD, TLS_GD): Define them. * sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela): Support new relocs for TLS. * sysdeps/powerpc/dl-tls.h (TLS_TP_OFFSET, TLS_DTV_OFFSET): Move these macros out of [SHARED]. (TLS_TPREL_VALUE, TLS_DTPREL_VALUE): New macros. * elf/elf.h: Define R_PPC_* relocs for TLS support. Clean up R_PPC64_* macro definition comments. --- linuxthreads/descr.h | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) (limited to 'linuxthreads/descr.h') diff --git a/linuxthreads/descr.h b/linuxthreads/descr.h index d266ffb126..2dcb37642a 100644 --- a/linuxthreads/descr.h +++ b/linuxthreads/descr.h @@ -23,6 +23,7 @@ #include #include #include +#include /* Fast thread-specific data internal to libc. */ enum __libc_tsd_key_t { _LIBC_TSD_KEY_MALLOC = 0, @@ -106,11 +107,14 @@ typedef struct _pthread_rwlock_info { union dtv; - -struct _pthread_descr_struct { - /* XXX Remove this union for IA-64 style TLS module */ - union { - struct { +struct _pthread_descr_struct +{ +#if !defined USE_TLS || !TLS_DTV_AT_TP + /* This overlaps tcbhead_t (see tls.h), as used for TLS without threads. */ + union + { + struct + { void *tcb; /* Pointer to the TCB.
