2016-02-17xtensa: fix .init/.fini literals movingMax Filippov1-2/+10
Despite the documentation and the comment in xtensa_move_literals, in the presence of --text-section-literals and --auto-litpools literals are moved from the separate literal sections into .init and .fini, because the check in the xtensa_move_literals is incorrect. This moving was broken with introduction of auto litpools: some literals now may be lost. This happens because literal frags emitted from .init and .fini are not closed when new .literal_position marks new literal pool. Then frag_align(2, 0, 0) changes type of the last literal frag to rs_align. rs_align frags are skipped in the xtensa_move_literals. As a result fixups against such literals are not moved out of .init.literal/ .fini.literal sections producing the following assembler error: test.S: Warning: fixes not all moved from .init.literal test.S: Internal error! Fix check for .init.literal/.fini.literal in the xtensa_move_literals and don't let it move literals from there in the presence of --text-section-literals or --auto-litpools. 2016-02-17 Max Filippov <jcmvbkbc@gmail.com> gas/ * config/tc-xtensa.c (xtensa_move_literals): Fix check for .init.literal/.fini.literal section name. * testsuite/gas/xtensa/all.exp: Add init-fini-literals to the list of xtensa tests. * testsuite/gas/xtensa/init-fini-literals.d: New file: init-fini-literals test result patterns. * testsuite/gas/xtensa/init-fini-literals.s: New file: init-fini-literals test.

2016-02-03Add -mrelax-relocations= to x86 assemblerH.J. Lu1-3/+27
The x86 relax relocations introduced in binutils 2.26 aren't supported by linker on Solaris older than Solaris 12. To use x86 assembler with older Solaris linker, this patch adds 1. A command line option -mrelax-relocations= to x86 assembler to control whether to generate relax relocations. 2. A configure option --enable-x86-relax-relocations to decide whether x86 assembler should generate relax relocations by default. It is defaulted to yes, except for x86 Solaris targets older than Solaris 12. gas/ PR gas/19520 * NEWS: Mention new command line option -mrelax-relocations and new configure option --enable-x86-relax-relocations for x86 target. * config.in: Regenerated. * configure.ac: Add --enable-x86-relax-relocations.

2016-02-03msp430: Set DWARF2_ADDR_SIZE to 4.Kevin Buettner1-0/+2
This change makes gas's notion of the msp430 dwarf2 address size match that of gcc and gdb. This is needed so that the format of addresses generated for DW_LNE_set_address in .debug_line will match the address size for the compilation unit. In gcc/config/msp430/msp430.h, it's set to 4: #define DWARF2_ADDR_SIZE 4 Likewise in gdb/msp430-tdep.c: set_gdbarch_dwarf2_addr_size (gdbarch, 4); (As far as I can tell, however, GDB doesn't use this value when decoding .debug_line. Instead, GDB uses the Pointer Size from the compilation unit.) readelf is able to seamlessly handle mismatches between these various sizes by using the size of the DW_LNE_set_address instruction to determine the address size. Another way to fix this problem is to make GDB behave in a similar manner. In my opinion, GDB should detect and inform the user about these mismatches; it's not clear to me if it's correct for GDB to go ahead and read the address anyway when a size mismatch is detected. Without this change, addresses in .debug_line are encoded in two bytes for some multilibs. When GDB reads the address for DW_LNE_set_address, it uses the pointer size provided by the CU. When these values don't match, GDB reads the wrong number of bytes. In the cases that I've looked at, GDB is reading 4 bytes from a 2 byte container, which results in a garbage address. GDB discards lines which have a bogus address; the end result is that GDB records no line number information for CUs which have a mismatch between the address size (from the CU) and the format of the address used by DW_LNE_set_address. gas/ChangeLog: * config/tc-msp430.h (DWARF2_ADDR_SIZE): Set to 4.

2015-12-14[AArch64][PATCH 11/14] Add support for the 2H vector type.Matthew Wahab1-7/+6
ARMv8.2 adds 16-bit floating point operations as an optional extension to the floating point and Adv.SIMD support. The FP16 additions to the scalar pairwise group introduce a new vector type, 2H. This patch adds support for this vector type to binutils. The patch adds a new operand qualifier to the enum aarch64.h:aarch64_opnd_qualifier. This interferes with the calculation used by aarch64-dis.c:get_vreg_qualifier_from_value, called when decoding an instruction. Since the new vector type is only used in FP16 scalar pairwise instructions which do not require the function, this patch adjusts the function to ignore the new qualifier. gas/ 2015-12-14 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (parse_neon_type_for_operand): Adjust to take into account new vector type 2H.

2015-12-14[AArch64][PATCH 10/14] Rework code mapping vector types to operand qualifiers.Matthew Wahab1-6/+30
ARMv8.2 adds 16-bit floating point operations as an optional extension to the floating point and Adv.SIMD support. The FP16 additions to the scalar pairwise group introduce a new vector type. This patch reworks code in the assembler to allow the addition of the new type. The new vector type requires the addtion of a new operand qualifier to the enum aarch64_opnd_qualifier which is defined include/opcodes/aarch64.h, in the group prefixed by AARCH64_OPN_QLF_V_. The correctness of the GAS utility function tc-aarch64.c:vectype_to_qualifier is heavily dependent on the number and ordering of this group. In particular, it makes assumptions about the positions of the members of the group that are not true if a qualifier for type 2H is added before the qualifier for 4H. This patch reworks the function to weaken its assumptions, making it calculate positions in the group from the type (B, H, S, D, Q) and register width. gas/ 2015-12-14 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (vectype_to_qualifier): Calculate operand qualifier from per-type base and offet.

2015-12-11[AArch64][Patch 5/5] Add instruction PSB CSYNCMatthew Wahab1-1/+55
The Statistical Profile Extension adds the instruction PSB CSYNC as an alias for the HINT #17 instruction. This patch adds the instruction to binutils as a HINT alias that takes an operand. A new operand type, AARCH64_OPND_BARRIER_PSB, is added to represent the operand to PSB. A parser for the operand type is added to the assembler and a printer to the disassembler. The operand name "csync" is added to the list of HINT options with HINT number #17. Encoding and decoding of the operand is handled by the ins_hint/ext_hint functions added in the preceding patches. gas/ 2015-12-11 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_hint_opt_hsh): New.

The Statistical Profile extension included in the ARMv8.2 architecture adds a number of system registers and a new instruction. This patch set adds support for the extension to binutils, enabled when -march=armv8.2-a+profile is given. The patches in this series: - Add the new command line option and feature flags. - Add the new system registers. - Adjust the maximum number of aliases permitted for an instruction. - Add support for HINT aliases which take operands. - Add the new instruction, an alias of the HINT instruction.

2015-12-10arc/gas: Accept, but ignore, dummy arguments.Andrew Burgess1-1/+2
There's a set of legacy command line arguments that the arc assembler still accepts, however, these arguments not longer have any effect on the assembler. Currently we return false from md_parse_option for all of these arguments, with the result that the assembler terminates with an error message. We should return true indicating that the argument has been accepted, even though we ignore it. gas/ChangeLog: * config/tc-arc.c (md_parse_option): Return 1 in order to accept dummy arguments.

2015-12-09sparc: support %dN and %qN syntax for FP registers.Jose E. Marchesi1-5/+11
The SPARC Refence Manual documents the %dN and %qN syntax to refer to double and quad-precision floating-point registers, respectively. See OSA2015 Appendix C, Assembly Language Syntax, C1.1 Register Names. This patch adds support for these names to GAS. This eases the porting of software from Solaris to GNU/Linux, as these register names have been supported by the Solaris linker for a long time and many assembler require that support. gas/ChangeLog: 2015-12-09 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (sparc_ip): Support %dN and %qN notation for double and quad-precision floating-point registers.
