2016-06-14Set my_archive for thin archivesAlan Modra9-11/+35
LTO plugin support in plugin_maybe_claim wants to close the IR bfd after replacing it with the recompiled object, but can't do so for archive elements due to various pointers that access the archive bfd. Thin archives have the same problem. They too cannot have their element bfds closed.

2016-06-08Support i386 TLS code sequences without PLTH.J. Lu2-65/+197
We can generate i386 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *___tls_get_addr@GOT(%reg) where EBX register isn't required as GOT base, instead of direct call: call ___tls_get_addr[@PLT] which requires EBX register as GOT base. Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, 7-byte lea instruction before call instruction is replaced by 6-byte one to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte lea instruction. Since linker may convert call ___tls_get_addr[@PLT] to addr32 call ____tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-i386.c (elf_i386_link_hash_entry): Add tls_get_addr.

2016-06-07PowerPC VLEAlan Modra7-33/+128
VLE is an encoding, not a particular processor architecture, so it isn't really proper to select insns based on PPC_OPCODE_VLE. For example {"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}}, {"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}}, shows two insns that have the same encoding, both available with VLE. Enabling both with VLE means we can't disassemble the second variant even if -Maltivec is given rather than -Mspe. Also, we don't check user assembly against the processor type as well as we could. Another problem is that when using the VLE encoding, insns from the main ppc opcode table are not available, except those using opcode 4 and 31. Correcting this revealed two errors in the ld testsuite, use of "nop" and "rfmci" when -mvle. This patch fixes those problems in the opcode table, and removes PPCNONE. I find a plain 0 distracts less from other values. In addition, I've implemented code to recognize some machine values from the apuinfo note present in ppc32 objects. It's not a complete disambiguation since we're lacking info to detect newer chips, but what we have should help with disassembly. include/ * elf/ppc.h (APUINFO_SECTION_NAME, APUINFO_LABEL, PPC_APUINFO_ISEL, PPC_APUINFO_PMR, PPC_APUINFO_RFMCI, PPC_APUINFO_CACHELCK, PPC_APUINFO_SPE, PPC_APUINFO_EFS, PPC_APUINFO_BRLOCK, PPC_APUINFO_VLE: Define. opcodes/ * ppc-dis.c (ppc_opts): Delete extraneous parentheses.

2016-05-28MIPS/BFD: Enable local R_MIPS_26 overflow detectionMaciej W. Rozycki2-8/+16
The original MIPS SVR4 psABI defines the calculation for the R_MIPS_26 relocation in a complex way, as follows[1]: Name Value Field Symbol Calculation R_MIPS_26 4 T-targ26 local (((A << 2) | \ (P & 0xf0000000)) + S) >> 2 4 T-targ26 external (sign-extend(A << 2) + S) >> 2 This is further clarified, by correcting typos (already applied in the excerpt above) in the 64-bit psABI extension[2]. A note is included in both documents to specify that for the purpose of relocation processing a local symbol is one with binding STB_LOCAL and type STT_SECTION, and otherwise, a symbol is external. We have both calculations implemented for the R_MIPS_26 relocation, and by extension also for the R_MIPS16_26 and R_MICROMIPS_26_S1 relocations, from now on collectively called jump relocations. However our code uses a different condition to tell local and external symbols apart, that is it only checks for the STB_LOCAL binding and ignores the symbol type, however for REL relocations only. The external calculation is used for all RELA jump relocations. In reality the difference matters for jump relocations referring local MIPS16 and, as from recent commit 44d3da233815 ("MIPS/GAS: Treat local jump relocs the same no matter if REL or RELA"), also local microMIPS symbols. Such relocations are not converted to refer to corresponding section symbols instead and retain the original local symbol reference. It can be inferred from the relocation calculation definitions that the addend is effectively unsigned for the local case and explicitly signed for the external case. With the REL relocation format it makes sense given the limited range provided for by the field being relocated: the use of an unsigned addend expands the range by one bit for the local case, because a negative offset from a section symbol makes no sense, and any usable negative offset from the original local symbol will have worked out positive if converted to a section-relative reference. In the external case a signed addend gives more flexibility as offsets both negative and positive can be used with a symbol. Any such offsets will typically have a small value. The inclusion of the (P & 0xf0000000) component, ORed in the calculation in the local case, seems questionable as bits 31:28 are not included in the relocatable field and are masked out as the relocation is applied. Their value is therefore irrelevant for output processing, the relocated field ends up the same regardless of their value. They could be used for overflow detection, however this is precluded by adding them to bits 31:28 of the symbol referred, as the sum will not correspond to the value calculated by the processor at run time whenever bits 31:28 of the symbol referred are not all zeros, even though it is valid as long they are the same as bits 31:28 of P. We deal with this problem by ignoring any overflow resulting from the local calculation. This however makes us miss genuine overflow cases, where 31:28 of the symbol referred are different from bits 31:28 of P, and non-functional code is produced. Given the situation, for the purpose of overflow detection we can change our code to follow the original psABI and only treat the in-place addend as unsigned in the section symbol case, permitting jumps to offsets 128MiB and above into section. Sections so large may be uncommon, but still a reasonable use case. On the other hand such large offsets from regular local symbols are not expected and it makes sense to support (possibly small) negative offsets instead, also in consistency with what we do for global symbols. Drop the (P & 0xf0000000) component then, treat the addend as signed with local non-section symbols and also detect an overflow in the result of such calculation with local symbols. NB it does not affect the value computed for the relocatable field, it only affects overflow detection.

2016-05-28Return void from linker callbacksAlan Modra95-1388/+953
The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure". This patch removes the status return on the callbacks that always return true. I kept the return status for "notice" because that one does happen to need to return "out of memory". include/ * bfdlink.h (struct bfd_link_callbacks): Update comments.

2016-05-27MIPS/BFD: Fix section symbol name fetching in relocationMaciej W. Rozycki2-1/+7
Symbol table entries for section symbols are different between IRIX and traditional MIPS ELF targets in that IRIX entries have their `st_name' member pointing at the section's name in the string table section, while traditional entries have 0 there and the section header string table has to be referred via the relevant section header's `shn_name' member instead. This is chosen with the `elf_backend_name_local_section_symbols' backend and can be observed with `readelf -s' output for an IRIX object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 .text 2: 00000000 0 SECTION LOCAL DEFAULT 3 .data 3: 00000000 0 SECTION LOCAL DEFAULT 4 .bss 4: 00000000 0 SECTION LOCAL DEFAULT 5 .reginfo 5: 00000000 0 SECTION LOCAL DEFAULT 6 .MIPS.abiflags 6: 00000000 0 SECTION LOCAL DEFAULT 7 .pdr 7: 00000000 0 SECTION LOCAL DEFAULT 9 .gnu.attributes 8: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 9: 00004008 0 FUNC LOCAL DEFAULT 1 abar 10: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar and a corresponding traditional object: Symbol table '.symtab' contains 12 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 2: 00000000 0 SECTION LOCAL DEFAULT 3 3: 00000000 0 SECTION LOCAL DEFAULT 4 4: 00004008 0 FUNC LOCAL DEFAULT 1 abar 5: 00002008 0 FUNC LOCAL DEFAULT 1 afoo 6: 00000000 0 SECTION LOCAL DEFAULT 5 7: 00000000 0 SECTION LOCAL DEFAULT 6 8: 00000000 0 SECTION LOCAL DEFAULT 7 9: 00000000 0 SECTION LOCAL DEFAULT 9 10: 00002000 16 FUNC GLOBAL DEFAULT 1 foo 11: 00004000 16 FUNC GLOBAL DEFAULT 1 bar respectively. Consequently the right way to retrieve a section symbol's name has to be chosen in `mips_elf_calculate_relocation' for the purpose of error reporting. Originally we produced symbol tables in the traditional object format only and we handled it correctly until it was lost in a rewrite with: commit 7403cb6305f5660fccc8869d3333a731102ae978 Author: Mark Mitchell <mark@codesourcery.com> Date: Wed Jun 30 20:13:43 1999 +0000 probably because of the extra pointer indirection added which made the same expression have a different meaning. With the addition of IRIX symbol table format with: commit 174fd7f9556183397625dbfa99ef68ecd325c74b Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Mon Feb 9 08:04:00 2004 +0000 the bug has been partially covered and now when a relocation error is triggered with an IRIX object the offending section symbol is correctly reported: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `.text' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `.text' because `bfd_elf_string_from_elf_section' retrieves the name from the string table section. With a traditional object however the function returns an empty string and consequently `no symbol' is printed instead: tmpdir/dump0.o: In function `foo': (.text+0x2000): relocation truncated to fit: R_MIPS_26 against `no symbol' tmpdir/dump0.o: In function `bar': (.text+0x4000): relocation truncated to fit: R_MIPS_26 against `no symbol' Restore the original semantics so that the section name is always correctly retrieved. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Also use the section name if `bfd_elf_string_from_elf_section' returns an empty string. ld/ * testsuite/ld-mips-elf/reloc-local-overflow.d: New test. * testsuite/ld-mips-elf/reloc-local-overflow.s: Source for the new test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

2016-05-25MIPS/BFD: Report `bfd_reloc_outofrange' errors as suchMaciej W. Rozycki2-2/+9
A `bfd_reloc_outofrange' condition from `mips_elf_calculate_relocation' currently triggers the warning callback, which in the case of LD prints messages like: foo.o: In function `foo': (.text+0x0): warning: JALX to a non-word-aligned address or: foo.o: In function `foo': (.text+0x0): warning: PC-relative load from unaligned address and nothing else, which suggests this is a benign condition and link has otherwise successfully run to completion. This is however not the case, the link terminates right away with no further messages and no output produced. Use the general error or warning info callback then, preserving the message format. Also set a BFD error condition so that a failure is unambiguously reported. Complement the change with a set of suitable test suite additions. bfd/ * elfxx-mips.c (_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Call `->einfo' rather than `->warning'.
