2016-09-30Make bfd_error_handler_type like vprintfAlan Modra1-5/+2
It was like printf, which means you can't use bfd_set_error_handler to hook in a function to do something and then call the original handler.

(_bfd_error_internal): Rename from _bfd_error_handler. Make static. (error_handler_internal): New function, split out from.. (_bfd_default_error_handler): ..here. Rename to _bfd_error_handler.

2016-06-17bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine ↵Jose E. Marchesi1-2/+18
numbers. This patch adds support for the opcode architectures SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}. Note that for arches up to v9b (UltraSPARC III), the detection of the BFD machine type was based on the bits in the e_machine field of the ELF header. However, there are no more available bits in that field, so this patch takes the approach of using the hardware capabilities stored in the object attributes HWCAPS/HWCAPS2 in order to characterize the machine the object was built for. bfd/ChangeLog: 2016-06-17 Jose E.

2016-06-07PowerPC VLEAlan Modra1-7/+0
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.

2016-05-03[AArch64] Also puts value in place for R_AARCH64_RELATIVEJiong Wang1-2/+2
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added.

2016-03-21arc: Add nps400 machine type, and assembler flag.Andrew Burgess1-0/+1
This commit introduces the nps400 machine type as a variant of arc. There's a new flag in the assembler to select this machine type. All other changes are just adding handling of the new machine type into the relevant places. The nps400 is an arc700 variant with some vendor specific instructions added into the instruction set. This commit does not add any of the new instructions, this is just laying the groundwork for future commits. However, in preparation for these new instructions a new opcode define for nps400 has been added to include/opcode/arc.h, this new opcode define is used in the assembler and disassembler along with the existing define for arc700 such that when assembling and disassembling for nps400 the user will have access to all arc700 instructions and all the nps400 vendor extension instructions. bfd/ChangeLog: * archures.c (bfd_mach_arc_nps400): Define. * bfd-in2.h: Regenerate. * cpu-arc.c (arch_info_struct): New entry for nps400, renumber some existing entries to make space. * elf32-arc.c (arc_elf_object_p): Add nps400 case.

2015-12-16[ARM] Add support for thumb1 pcrop relocations.Mickael Guene1-0/+6
To support thumb1 execute-only code we need to support four new relocations (R_ARM_THM_ALU_ABS_G0_NC, R_ARM_THM_ALU_ABS_G1_NC, R_ARM_THM_ALU_ABS_G2_NC and R_ARM_THM_ALU_ABS_G3_NC). These relocations allow the static linker to finalize construction of symbol address. Typical sequence of code to get address of the symbol foo is then the following : movs r3, #:upper8_15:#foo lsls r3, #8 adds r3, #:upper0_7:#foo lsls r3, #8 adds r3, #:lower8_15:#foo lsls r3, #8 adds r3, #:lower0_7:#foo This will give following sequence of text and relocations after assembly : 4: 2300 movs r3, #0 4: R_ARM_THM_ALU_ABS_G3_NC foo 6: 021b lsls r3, r3, #8 8: 3300 adds r3, #0 8: R_ARM_THM_ALU_ABS_G2_NC foo a: 021b lsls r3, r3, #8 c: 3300 adds r3, #0 c: R_ARM_THM_ALU_ABS_G1_NC foo e: 021b lsls r3, r3, #8 10: 3300 adds r3, #0 10: R_ARM_THM_ALU_ABS_G0_NC foo

This patch adds support for the R_386_GOT32X relocation proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I to gas and ld.

2015-09-29Don't use the output section size to copy input sectionH.J. Lu1-1/+2
We can't use the output section size to copy input section since --interleave will shrink the output section. Instead, we change bfd_convert_section_contents to return the updated input section size. When we do that, we don't need to adjust the output section size to skip gap fills. bfd/ PR binutils/19020 * bfd.c (bfd_convert_section_contents): Add ptr_size parameter. * bfd-in2.h: Regenerated. binutils/ PR binutils/19020 * objcopy.c (copy_object): Don't adjust the output section size when copying from input sections.
