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.

2015-01-29Correct PowerPC64 local-dynamic TLS linker optimizationAlan Modra6-2/+189
The linker hardcoded r3 into a local-dynamic to local-exec TLS optimization sequence. This is normally the case since r3 is required as a parameter to (the optimized out) __tls_get_addr call. However, it is possible for a compiler, LLVM in this case, to set up the parameter value in another register then copy it to r3 before the call. When fixing this problem, I noticed that ppc32 had another bug when optimizing away one of the TLS insns to a nop. The patch also tidies a mask used by global-dynamic to initial-exec TLS optimization, to just select the fields needed. Leaving the offset in the instruction wasn't a bug since it will be overwritten anyway. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Correct GOT_TLSLD optimization.

2015-01-20ld: Don't evaluate unneeded PROVIDE expressions.Andrew Burgess11-2/+95
When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined. Display a special message for PROVIDE'd symbols that are not being provided. ld/testsuite/ChangeLog: * ld-scripts/provide-4.d: New file. * ld-scripts/provide-4-map.d: New file. * ld-scripts/provide-4.t: New file. * ld-scripts/provide-5.d: New file. * ld-scripts/provide-5.s: New file. * ld-scripts/provide-5-map.d: New file. * ld-scripts/provide-5.t: New file. * ld-scripts/provide.exp: Run the provide-4.d and provide-5.d tests.
2015-01-20ld/testing: run_dump_test can now check linker mapfiles.Andrew Burgess4-9/+42
Add a new option 'map' to the ld run_dump_test mechanism. When the 'map' option is given run_dump_test will ensure that there is a -Map=MAPFILE present in the linker command line, adding one if needed. The MAPFILE is then compared with the file passed to the new 'map' option using the regexp_diff function. This should make it slightly easier to write tests that check the linker mapfile output. The only test I found that already compares mapfile content is updated to use the new mechanism. ld/testsuite/ChangeLog: * ld-scripts/overlay-size.d: Add 'map' option. * ld-scripts/overlay-size.exp: Remove manual check of mapfile. * lib/ld-lib.exp (run_dump_test): Add support for new 'map' option, checking linker mapfile output.
2015-01-20Reorder more powerpc64 sections for -z relroAlan Modra14-123/+75
This moves .got too, which requires .sdata and .sbss to move with it, because these sections share addressing via the toc pointer and with small-model code must be within a 16-bit signed offset. .plt, .iplt and .branch_lt must also be moved since they are addressed via a 32-bit offset from the toc pointer, and we might have a very large .data section. This change means we may have some bss style sections before the data segment, necessitating another PT_LOAD header. Also, since _edata is defined at the end of the data segment it's possible with an empty .data to have _edata at the end of .plt which looks a little unusual since .plt is a bss style section. That should only happen rarely in real world binaries, but does occur in the ld testsuite. ld/ * emulparams/elf64ppc.sh (BSS_PLT): Don't define. (OTHER_READWRITE_SECTIONS): Move .branch_lt to..

2014-12-24AVR: Assembler now prepares for linker relaxation by default.Andrew Burgess6-7/+16
Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment. (enum options): Add new OPTION_NO_LINK_RELAX. (md_longopts): Add entry for -mno-link-relax. (md_parse_option): Handle OPTION_NO_LINK_RELAX, and update OPTION_LINK_RELAX. (md_begin): Initialise linkrelax from no_link_relax. (md_show_usage): Include -mno-link-relax option.

2014-12-24Don't create .eh_frame_hdr on shared lib bfdAlan Modra2-1/+10
If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data. PR 17742 * ld/emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Exclude shared libraries in loop looking for .eh_frame sections. Similarly for build-id loop.
