* [Patch ARM] Fix build attributes for armv8-a in case of assembler files that ↵Ramana Radhakrishnan2015-12-171-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | contain no directives. There is currently a problem in the way in which we produce build attributes for simple assembler files that have armv8-a instructions. In these case we need to generate TAG_ISA_THUMB_Use to be Thumb-2 and set the architecture profile to be 'A' rather than not setting architecture profile to be 'A' and setting TAG_ISA_THUMB_Use to be Thumb-1. This is a pre-requisite for any v8-m patches that have been posted. arm-none-eabi gas testsuite run. no regressions. 2015-12-17 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> * gas/config/tc-arm.c (aeabi_set_public_attributes): Adjust TAG_ARCH_profile for armv8-a. * gas/testsuite/gas/arm/armv8a-automatic-hlt.d: New test. * gas/testsuite/gas/arm/armv8a-automatic-hlt.s: New test. * gas/testsuite/gas/arm/armv8a-automatic-lda.d: New test. * gas/testsuite/gas/arm/armv8a-automatic-lda.s: New test.

* [ARM] Add support for thumb1 pcrop relocations.Mickael Guene2015-12-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* [AArch64][PATCH 11/14] Add support for the 2H vector type.Matthew Wahab2015-12-142-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv8.2 adds the new system instruction DC CVAP.

* [AArch64][PATCH 1/2] Add support for RAS instruction ESB.Matthew Wahab2015-12-102-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARMv8.2 RAS extension adds a new barrier instruction ESB as an alias and the preferred form of HINT 16. This patch adds an architectural feature flag for the RAS extension and includes it in the features selected enabled by -march=armv8.2-a. It also adds the ESB instruction, making it available whenever the RAS feature is enabled. Because ESB is the preferred form and because the target architecture isn't available to the disassembler, HINT 16 will be disassembled as ESB even when the target has no support for the RAS extension. gas/testsuite/ 2015-12-10 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/system-2.d: New. * gas/aarch64/system-2.s: New. * gas/aarch64/system.d: Adjust expected output for HINT 16. include/opcode/ 2015-12-10 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (AARCH64_FEATURE_RAS): New.

For example, with: template<int> struct A {}; template <typename Y> void function_temp(A<sizeof ((Y)(999))>) {} template void function_temp<int>(A<sizeof (int)>); The 'function_temp<int>' instantiation above mangles to: _Z13function_tempIiEv1AIXszcvT_Li999EEE The demangler parses this as: typed name template name 'function_temp' template argument list builtin type int function type builtin type void argument list template (*) name 'A' template argument list unary operator operator sizeof unary operator cast template parameter 0 (**) literal builtin type int name '999' And after the fix for 59195, due to: static void d_print_cast (struct d_print_info *dpi, int options, const struct demangle_component *dc) { ... /* For a cast operator, we need the template parameters from the enclosing template in scope for processing the type. */ if (dpi->current_template != NULL) { dpt.next = dpi->templates; dpi->templates = &dpt; dpt.template_decl = dpi->current_template; } when printing the template argument list of A (what should be "<sizeof (int)>"), the template parameter 0 (that is, "T_", the '**' above) now refers to the first parameter of the the template argument list of the 'A' template (the '*' above), exactly what we were already trying to print. This leads to infinite recursion, and stack exaustion. The template parameter 0 should actually refer to the first parameter of the 'function_temp' template. Where it reads "for the cast operator" in the comment in d_print_cast (above), it's really talking about a conversion operator, like: struct A { template <typename U> explicit operator U(); }; We don't want to inject the template parameters from the enclosing template in scope when processing a cast _expression_, only when handling a conversion operator. The problem is that DEMANGLE_COMPONENT_CAST is currently ambiguous, and means _both_ 'conversion operator' and 'cast expression'. Fix this by adding a new DEMANGLE_COMPONENT_CONVERSION component type, which does what DEMANGLE_COMPONENT_CAST does today, and making DEMANGLE_COMPONENT_CAST just simply print its component subtree. I think we could instead reuse DEMANGLE_COMPONENT_CAST and in d_print_comp_inner still do: @@ -5001,9 +5013,9 @@ d_print_comp_inner (struct d_print_info *dpi, int options, d_print_comp (dpi, options, dc->u.s_extended_operator.name); return; case DEMANGLE_COMPONENT_CAST: d_append_string (dpi, "operator "); - d_print_cast (dpi, options, dc); + d_print_conversion (dpi, options, dc); return; leaving the unary cast case below calling d_print_cast, but seems to me that spliting the component types makes it easier to reason about the code. g++'s testsuite actually generates three symbols that crash the demangler in the same way. I've added those as tests in the demangler testsuite as well. And then this fixes PR other/61233 too, which happens to be a demangler crash originally reported to GDB, at: https://sourceware.org/bugzilla/show_bug.cgi?id=16957 Bootstrapped and regtested on x86_64 Fedora 20. Also ran this through GDB's testsuite.

* [AArch64] Add ARMv8.2 instructions BFC and REV64.Matthew Wahab2015-11-272-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as an alias for REV. This patch set adds support for these to binutils, enabled when the -march=armv8.2-a is given. It depends on the support for an instruction being its preferred form which was added in an earlier patch. This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred form for BFM when the source is a zero register and the conditions for using the BFI form are met (in other words, BFC is the preferred form for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register). gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/alias-2.d: New. * gas/aarch64/alias-2.s: New. include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (aarch64_op): Add OP_BFC. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-asm.c (convert_bfc_to_bfm): New.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv8.2 adds optional support for 16-bit operations to the FP and Adv.SIMD instructions.

Although the command line option is added as an architecture extension, it only affects instructions available with when +fp or +simd is enabled. If +fp16 is specified then it will also enable +fp. There are currently no FP16 instructions implemented in binutils, this patch is to enable subsequent work on supporting the extension. gas/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * config/tc-aarch64.c (aarch64_features): Add "fp16". * doc/c-aarch64.texi (Architecture Extensions): Add "fp16". include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (AARCH64_FEATURE_F16): New.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nowadays aarch64_decode_insn is a public interface used by both opcodes and gdb. However, its behaviour relies on a global variable no_aliases, which isn't a good practise. On the other hand, In default, no_aliases is zero, but in GDB, we do want no alias when decoding instructions for prologue analysis (patches to be posted), so that we can handle both instructions "add" and "mov" (an alias of "add") as "add". The code in GDB can be simplified. This patch adds a new argument in aarch64_decode_insn, and pass no_aliases to it. In GDB side, always pass 1 to it. include/opcode: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64.h (aarch64_decode_insn): Update declaration. opcodes: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64-dis.c (aarch64_decode_insn): Add one argument noaliases_p.

It updates gas to generate R_X86_64_GOTPCRELX, R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory operand, foo@GOTPCREL(%rip). With the locally defined symbol, foo, we convert mov foo@GOTPCREL(%rip), %reg to lea foo(%rip), %reg and convert call/jmp *foo@GOTPCREL(%rip) to nop call foo/jmp foo nop When PIC is false, convert test %reg, foo@GOTPCREL(%rip) to test $foo, %reg and convert binop foo@GOTPCREL(%rip), %reg to binop $foo, %reg where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions. bfd/ * elf64-x86-64.c: Include opcode/i386.h.
