2015-02-18Properly place the NULL STT_FILE symbol revistitedAlan Modra29-52/+69
I was having a little closer look at what is going on here and noticed that HJ unconditionally emits a NULL STT_FILE symbol before emitting forced local symbols. That means we really don't need a second pass over forced local symbols. The only reason for two passes is when some forced local symbol can be emitted before the NULL STT_FILE. So I set about removing the second pass, updating the testsuite all over again. It's also unnecessary to emit the NULL STT_FILE when no previous file symbol has been emitted. bfd/ PR ld/17975 * elflink.c (struct elf_outext_info): Remove need_second_pass and second_pass. (elf_link_output_extsym): Delete code handling second forced local pass. Move code emitting NULL STT_FILE symbol later, so that it can be omitted if forced local is stripped.

2015-02-14PR ld/17973 LTO file symsAlan Modra5-5/+29
LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

2015-02-11Merge linker plugin handling into BFD plugin supportH.J. Lu1-32/+73
Linker plugin_maybe_claim is the interface of linker plugin support. This patch extracts linker plugin_maybe_claim into plugin_object_p and makes it available to BFD via a new function: void register_ld_plugin_object_p (const bfd_target *(*) (bfd *)); bfd_plugin_object_p calls plugin_object_p registered by linker first. It adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim to retrieve it later. bfd/ PR ld/17878 * bfd.c (bfd_plugin_format): New.

2015-02-05Add plugin_input_file_tH.J. Lu2-16/+119
This patchs adds plugin_input_file_t to implement get_input_file, get_view and release_input_file. The maximum memeory overhead per IR input file are about 40 bytes for plugin_input_file_t plus the memory to store input IR filename. According to http://gcc.gnu.org/wiki/whopr/driver RELEASE_INPUT_FILE: Function pointer to the linker interface that releases a file descriptor for a claimed input file. The plug-in library must call this interface for each file descriptor obtained by the "get input file" interface. It must release all such file descriptors before returning from the WPA phase. However, GCC plug-in library doesn't use the "get input file" interface. It processed the IR input in the claim file handler. Since the the file descriptor opened for the IR input was unused after the claim file handler returns and GCC plug-in library before GCC 5 doesn't call the RELEASE_INPUT_FILE function pointer, ld closed the file descriptor to avoid leaking file descriptor. But this approach doesn't work with other plug-in libraries which uses the "get input file", "get view" and "release input file" interfaces. To avoid file descriptor leak with GCC prior to GCC 5 and support other plug-in libraries at the same time, we close the file descriptor only if the input IR file is a bfd_object file. This scheme doesn't work when a plug-in library needs the file descriptor and its IR is stored in bfd_object file. PR ld/17878 * plugin.c: Include <errno.h>. (errno): New. Declare if needed.
