From df9076abf90ec3d9d99be3b7772b8e9d9153bea5 Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Mon, 3 Mar 2003 20:00:35 +0000 Subject: [PATCH] * ldfile.h (struct search_dirs): Added sysrooted field. * ldlang.h (struct lang_input_statement_struct): Likewise. * ldfile.c (ldfile_add_library_path): Mark sysrooted paths. (ldfile_open_file_search): Look for sysrooted filename starting with / in ld_sysroot instead of in the current directory. Clear sysrooted flag if it's found in the current directory. Set it from the search directory's sysrooted flag where it is found otherwise. * ldlang.c (ldlang_sysrooted_script): New static variable. (new_afile): Mark search_file_enums as sysrooted if ldlang_sysrooted_script. (load_symbols): Set ldlang_sysrooted_script according to the script's sysrooted field while processing it. * ld.texinfo: Document INPUT behavior in sysroot. --- ld/ChangeLog | 17 +++++++++++++++++ ld/ld.texinfo | 11 +++++++---- ld/ldfile.c | 31 +++++++++++++++++++++++++++---- ld/ldfile.h | 6 ++++-- ld/ldlang.c | 7 +++++++ ld/ldlang.h | 6 ++++++ 6 files changed, 68 insertions(+), 10 deletions(-) diff --git a/ld/ChangeLog b/ld/ChangeLog index 7db7e0a0f8..fbb39f11cc 100644 --- a/ld/ChangeLog +++ b/ld/ChangeLog @@ -1,3 +1,20 @@ +2003-03-03 Alexandre Oliva + + * ldfile.h (struct search_dirs): Added sysrooted field. + * ldlang.h (struct lang_input_statement_struct): Likewise. + * ldfile.c (ldfile_add_library_path): Mark sysrooted paths. + (ldfile_open_file_search): Look for sysrooted filename starting + with / in ld_sysroot instead of in the current directory.
