ELF/LD: Avoid producing hidden and internal dynamic symbols Always turn hidden and internal symbols which have a dynamic index into local ones. This is required by the the ELF gABI[1]: "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." The ELF linker usually respects this requirement, however in the case where a dynamic symbol has been preallocated due to a reference of the default export class aka visibility from the object being linked, and then merged with a hidden or internal symbol definition from within the same object, then the original export class is carried over to the output dynamic symbol table, because while merging the generic ELF linker only converts affected dynamic symbols to local when they are defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The dynamic symbol produced confuses then the dynamic loader at the run time -- the hidden or internal export class is ignored and the symbol follows preemption rules as with the default export class. In the MIPS target it happens when `mips_elf_record_global_got_symbol' creates a dynamic symbol when a call relocation is encountered. Additionally if the undefined symbol referred by such a relocation does specify the intended export class, then a local dynamic symbol is created instead, which is harmless and allowed, but useless. Normally no local dynamic symbols are created, except for a single dummy one at the beginning. Correct the problem by removing the extra check for a dynamic symbol being defined or referenced by the object being linked and a dynamic object involved in the link both at a time. The test cases included cover the internal and hidden symbol cases, as well as a protected symbol for a reference, the handling of which is unchanged by this fix. Both cases described above are covered, that is where an internal or hidden dynamic symbol is produced and where a local one is. NB this change affects CRIS results where some symbols in the static table produced in a final link are now converted from STV_HIDDEN to STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler is called, so the affected symbols must have been chosen for entering into the dynamic symbol table, except in these test cases no such symbol table is produced. In fully linked binaries the static symbol table is only used for debugging though, so such a change is fine.

arc: Remove EF_ARC_CPU_GENERIC constant. The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h file, and is used in a few places in binutils, however, this constant should never make it into the elf header flags; we always set a valid cpu type in the assembler, which should then be copied over during linking. There are some non-gnu arc compilers that don't write an architecture type into the e_flags field, instead leaving the field as 0, which is the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine type to distinguish between the old and newer arc architectures, setting the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700 architectures, while using EM_ARC_COMPACT2 for newer arcem and archs architectures. Previously when displaying the machine flags for an older EM_ARC_COMPACT machine, if the e_flags had not been filled in, then we relied on the default case statement to display the message "Generic ARCompact", while in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC to print "ARC Generic", leaving the default case to print a message about unrecognised cpu flag. After this commit EF_ARC_CPU_GENERIC has been removed, for both machine types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case statement to handle the situation where the e_flags has not been filled in. The message displayed is now "Unknown ARCompact" (for older arc architectures) and "Unknown ARC" (for the newer architectures). The switch from "Generic" to "Unknown" in the message string is for clarity, calling the file "Generic" can give the impression that the file is compiled for a common sub-set of the architectures, and would therefore run on any type of machine (or at least any type of new or old machine depending on if the machine type is ARC or ARCv2). However, this was not what "Generic" meant, it really meant "Unknown", so that's what we now say. As part of the merging of the readelf flag reading code, I have unified the strings used in displaying the ELF ABI. This means that for older arc machines (arc600, arc601, and arc700) the string used for the original ABI, and ABIv2 have changed, the current ABIv3 remains the same. For the newer architectures (arcem and archs) the abi strings remain unchanged in all cases. bfd/ChangeLog: * elf32-arc.c (arc_elf_print_private_bfd_data): Remove use of EF_ARC_CPU_GENERIC.

Fix v850 bfd arch info printable names Currently, it's not possible to manually set some of the v850 archs in gdb: (gdb) set architecture v850<TAB> v850 (using old gcc ABI) v850-rh850 v850e v850e (using old gcc ABI) v850e1 [...] (gdb) set architecture v850 (using old gcc ABI) Ambiguous item "v850 (using old gcc ABI)". The problem is that "set architecture" is a GDB "enum command", and GDB only considers an enum value to be the string up until the first space. So writing "v850 (using old gcc ABI)" is the same as writing "v850", and then that's not an unambiguous arch printable name prefix. v850 is actually the only arch that has spaces in its printable name. One can conveniently see that with e.g.: (gdb) set max-completions unlimited (gdb) complete set architecture ... Rather than hack GDB into accepting this somehow, make v850 arch printable names more like the printable names of the other archs, and put the abi variant in the "machine" part, after a ':'. We now get: (gdb) set architecture v850<TAB> v850:old-gcc-abi v850:rh850 v850e v850e1 v850e1:old-gcc-abi v850e2 v850e2:old-gcc-abi [...] And now "set architecture v850:old-gcc-abi" works as expected. I ran the binutils/gas/ld testsuites, and found no regressions. I don't have a cross compiler handy, but I ran the gdb tests anyway, which covers at least some snoke testing. I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got broken with the previous 2012 change, since I hacked v850_rh850.sc to output "v850" and ld failed to grok it. I think it only works if the old GCC ABI is the configured v850 default ABI. That's now fixed by changing to use explicit v850:old-gcc-abi. Also, this actually "fixes" an existing GDB test, which isn't likewise expecting spaces in arch names, when GDB is configured for --target=v850: (gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures bfd/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * cpu-v850.c (N): Append ":old-gcc-abi" instead of " (using old gcc ABI)" to printable name. * cpu-v850_rh850.c (bfd_v850_rh850_arch): Use "v850:rh850" instead of "v850-rh850" as printable name. ld/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * scripttempl/v850.sc: Use "v850:old-gcc-abi" as OUTPUT_ARCH. * scripttempl/v850_rh850.sc: Use "v850:rh850" as OUTPUT_ARCH.

If the symbol address is known at the link-time, we can use it directly by changing instruction encoding. Indirect branch can only be converted to PC relative direct branch. MOV can be changed to LEA or encoded differently with signed address. The subset of binary operations can be encoded only with signed address. If undefined weak symbol is resolved to zero link-time, we can use it as address. Zero addresss can't used with PC relative direct branch when PIC is true since the current PC is unknown. In 64-bit, 32-bit relocation for PC relatiave direct branch to zero may also overflow.

[x86] Resolve non-PIC undefweak symbols in executable For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

Fix BFD format matching for x86_64-w64-mingw32 -m32 LTO. In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit 4a07dc81356ed8728e204e9aabeb256703c59aef), Kwok fixed a problem with the template used for a dummy BFD for an IR file for LTO on MinGW, where the input and output formats are not the same. A problem, however, remains in the case of linking for x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity between the pe-i386 and pei-i386 formats. An object (pe-i386) with plugin data is being tested by the linker to see what formats match. The default format initially set by the linker when bfd_check_format_matches is called is pei-i386 (as that's the output format from the linker script), which does not match, so the function goes on to the loop over possible BFD vectors. The pe-i386 vector matches, as it should. One other vector matches: the plugin vector. bfd_check_format_matches tests a vector for matching by temporarily modifying the BFD object to use that vector then using _bfd_check_format on it. So the BFD object is temporarily using plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which succeeds, having created a BFD based on link_info.output_bfd (because srctemplate is the BFD temporarily using plugin_vec, even after Kwok's patch link_info.output_bfd is all that's available to base the dummy BFD on). So we end up with a match from the plugin vector which uses the pei-i386 vector even though the pei-i386 vector itself does not match the input object. (In the i686-mingw32 case, as opposed to this multilib case, pe-i386 is the default BFD target, which would short-circuit that logic.) There are two cases of the linker handling inputs with a plugin: they may be inputs that are also accepted by some non-plugin BFD format, as here, or they may be a format that would not be recognized at all, as with some tests in the ld testsuite. In the former case, there is no need for BFD to accept the objects using the plugin vector, as the linker has its own logic to allow plugins to claim objects accepted by some other BFD vector. Thus, this patch arranges for the plugin vector to have the lowest match priority, and for the priority from that vector to be used in the relevant case (the attempted match to the plugin vector results in TEMP pointing to the pei-i386 vector). Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as well as verifying that it fixes the observed LTO issue for x86_64-w64-mingw32. * plugin.c (plugin_vec): Set match priority to 255. * format.c (bfd_check_format_matches) [BFD_SUPPORTS_PLUGINS]: When matching against the plugin vector, take priority from there not from TEMP.

bfd/arc: Add R_ prefix to all relocation names The convention within for relocation names is that they start with the string "R_", however, this is not so for ARC for the display names of relocations, however, internally, the names for the relocations types do have the 'R_' prefix. I suspect that the missing 'R_' on the output strings was an oversight, as I can't see any comment to the contrary.

MIPS/BFD: Move attribute check after ELF file header flag check We have a problem in that in making compatibility checks while merging private BFD data on the MIPS target we give priority to the attribute check, which may fail and cause the function to abort early on. The problem with this is the ABI compatibility aspect recorded in the attributes is relatively minor compared to aspects recorded in the ELF file header. However the premature exit causes any more important compatibility aspect violated to be masked and not reported to the user once a problem with attributes has been noticed. So move the attribute check after the ELF file header flag check in `_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely there. Take advantage of the resulting grouping of ELF file header handling together and remove the premature success return point for the first input object being handled, letting the code later on figure out output ABI flags even for this object. Update LD test cases according to messages from ELF file header checks now preceding ones from attribute checks. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Move attribute check after ELF file header flag check. ld/ * testsuite/ld-mips-elf/attr-gnu-4-14.d: Update the order of messages expected according to MIPS BFD private data merge changes. * testsuite/ld-mips-elf/attr-gnu-4-24.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-34.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-41.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-42.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-43.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-45.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-46.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-47.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-48.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-49.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-54.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-64.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-74.d: Likewise.
