2020-02-11[binutils][gas] Fix build failure with -std=c89Matthew Malcomson1-0/+5
My previous patch introduced the use of a C99 feature. C99 standard is not required for gas, so this feature should be removed. Committed as obvious. gas/ChangeLog: 2020-02-11 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-arm.c (vcx_handle_register_arguments): Remove `for` loop initial declaration.
2020-02-10[binutils][arm] Implement Custom Datapath Extensions for MVEMatthew Malcomson1-0/+38
Here we implement the custom datapath extensions for MVE. This required the following changes: - Adding a new register argument type (that takes either an MVE vector or a Neon S or D register). - Adding two new immediate operands types (0-127 and 0-4095). - Using the Neon type machinery to distinguish between instruction types. This required the introduction of new neon shapes to account for the coprocessor operands to these instructions. - Adding a new disassembly character to `print_insn_cde` to handle the new register types. Specification can be found at https://developer.arm.com/docs/ddi0607/latest Successfully regression tested on arm-none-eabi, and arm-wince-pe. gas/ChangeLog: 2020-02-10 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-arm.c (NEON_MAX_TYPE_ELS): Increment to account for instructions that can have 5 arguments.

2020-02-10[binutils][arm] arm support for ARMv8.m Custom Datapath ExtensionMatthew Malcomson1-0/+44
This patch is part of a series that adds support for the Armv8.m ARMv8.m Custom Datapath Extension to binutils. This patch introduces the Custom Instructions Class 1/2/3 (Single/ Dual, Accumulator/Non-accumulator varianats) to the arm backend. The following Custom Instructions are added: cx1, cx1a, cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da. Specification can be found at https://developer.arm.com/docs/ddi0607/latest This patch distinguishes between enabling CDE for different coprocessor numbers by defining multiple architecture flags. This means that the parsing of the architecture extension flags is kept entirely in the existing code path. We introduce a new IT block state to indicate the behaviour of these instructions. This new state allows being used in an IT block or outside an IT block, but does not allow the instruction to be used inside a VPT block. We need this since the CX*A instruction versions can be used in IT blocks, but they aren't to have the conditional suffixes on them. Hence we need to mark an instruction as allowed in either position. We also need a new flag to objdump, in order to determine whether to disassemble an instruction as CDE related or not.

2020-02-06ELF: Support the section flag 'o' in .section directiveH.J. Lu1-0/+24
As shown in https://sourceware.org/bugzilla/show_bug.cgi?id=25490 --gc-sections will silently remove __patchable_function_entries section and generate corrupt result. This patch adds the section flag 'o' to .section directive: .section __patchable_function_entries,"awo",@progbits,foo .section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat .section __patchable_function_entries,"awo",@progbits,bar,unique,4 .section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat,unique,1 which specifies the symbol name which the section references.

2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu1-0/+38
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.

2020-01-30x86: prevent undue use of GOT32X and alike relocationsJan Beulich1-0/+7
Comparison of i.tm.base_opcode against particular but not sufficiently specific values needs to be accompanied by other qualification. Exclude VEX and alike encodings here, and also exclude all forms of prefixes explicitly specified in the opcodes table. While using @GOT with such insns may not be very useful, it also isn't with e.g. ADC and SBB, yet these get explicitly listed in comments as supported.

Other than near returns these default to 32-bit operand size, and hence it isn't really unlikely that 64-bit forms are meant. Hence these should have disambiguating suffixes. In Intel mode, however, don't error in these cases unconditionally - MASM accepts these without suffix _and_ without warning.
2020-01-30x86: drop further pointless/bogus DefaultSizeJan Beulich1-0/+5
- 64-bit CALL permitting just a single operand size doesn't need it. - FLDENV et al should never have had it. It remains suspicious that a number of 64-bit only insns continue to have the attribute, despite this being intended for .code16gcc handling only.
2020-01-27x86-64: Properly encode and decode movsxdH.J. Lu1-0/+19
movsxd is a 64-bit only instruction. It supports both 16-bit and 32-bit destination registers. Its AT&T mnemonic is movslq which only supports 64-bit destination register. There is also a discrepancy between AMD64 and Intel64 on movsxd with 16-bit destination register. AMD64 supports 32-bit source operand and Intel64 supports 16-bit source operand. This patch updates movsxd encoding and decoding to alow 16-bit and 32-bit destination registers. It also handles movsxd with 16-bit destination register for AMD64 and Intel 64. gas/ PR binutils/25445 * config/tc-i386.c (check_long_reg): Also convert to QWORD for movsxd. * doc/c-i386.texi: Add a node for AMD64 vs. Intel64 ISA differences.

2020-01-27AArch64: Fix cfinv disassembly issuesTamar Christina1-0/+6
This fixes the preferred disassembly for cfinv. The Armv8.4-a instruction overlaps with the possible encoding space for msr. This because msr allows you to use unallocated encoding space using the general sA_B_cC_cD_E form. However when an encoding does become allocated then we need to ensure that it's used as the preferred disassembly. The problem with cfinv is that its mask has all bits sets because it has no arguments. This causes issues for the Alias resolver in gas as it uses the mask to build alias graph. In this case it can't do it since it thinks almost everything would alias with cfinv. So instead we can only fix this by moving cfinv before msr. gas/ChangeLog: PR 25403 * testsuite/gas/aarch64/armv8_4-a.d: Add cfinv. * testsuite/gas/aarch64/armv8_4-a.s: Likewise. opcodes/ChangeLog: PR 25403 * aarch64-tbl.h (struct aarch64_opcode): Re-order cfinv. * aarch64-asm-2.c: Regenerate * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise.

2020-01-21x86: replace adhoc ambiguous operand checking for CRC32Jan Beulich1-0/+14

2020-01-21x86: improve handling of insns with ambiguous operand sizesJan Beulich1-0/+45
Commit b76bc5d54e ("x86: don't default variable shift count insns to 8-bit operand size") pointed out a very bad case, but the underlying problem is, as mentioned on various occasions, much larger: Silently selecting a (nowhere documented afaict) certain default operand size when there's no "sizing" suffix and no suitable register operand(s) is simply dangerous (for the programmer to make mistakes). While in Intel syntax mode such mistakes already lead to an error (which is going to remain that way), AT&T syntax mode now gains warnings in such cases by default, which can be suppressed or promoted to an error if so desired by the programmer. Furthermore at least general purpose insns now consistently have a default applied (alongside the warning emission), rather than accepting some and refusing others. No warnings are (as before) to be generated for "DefaultSize" insns as well as ones acting on selector and other fixed-width values. For SYSRET, however, the DefaultSize needs to be dropped - it had been wrongly put there in the first place, as it's unrelated to .code16gcc (no stack accesses involved). As set forth as a prereq when I first mentioned this intended change a few years back, Linux as well as gcc have meanwhile been patched to avoid (emission of) ambiguous operands (and hence triggering of the new warning). Note that I think that in 64-bit mode IRET and far RET would better get a diagnostic too, as it's reasonably likely that a suffix-less instance really is meant to be a 64-bit one. But I guess I better make this a separate follow-on patch. Note further that floating point operations with integer operands are an exception for now: They continue to use short (16-bit) operands by default even in 32- and 64-bit modes. Finally note that while {,V}PCMPESTR{I,M} would, strictly speaking, also need to be diagnosed, with their 64-bit forms not being very useful I think it is better to continue to avoid warning about them (by way of them carrying IgnoreSize attributes).
2020-01-21x86: VCVTNEPS2BF16{X,Y} should permit broadcastingJan Beulich1-0/+9
Just like other VCVT*{X,Y} templates do, and to allow the programmer flexibility (might be relevant in particular when heavily macro-izing code), the two templates should also have Broadcast set, just like their X/Y-suffix-less counterparts. This in turn requires them to also have * Dword set on their memory operands, to cover the logic added to i386gen by 4a1b91eabbe7 ("x86: Expand Broadcast to 3 bits"), * RegXMM/RegYMM set on their source operands, to satisfy broadcast sizing logic in gas itself. Otherwise ATTSyntax templates wouldn't need such operand size attributes. While extending the test cases, also add Intel syntax broadcast forms without explicit size specifiers.

For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix even if it isn't required. Otherwise linker can’t safely perform GDesc -> IE/LE optimization. X32 TLSDESC sequences can be: 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg ... 67 ff 10 call *x@TLSCALL(%eax) or the same sequence as LP64: 48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg ... ff 10 call *foo@TLSCALL(%rax) We need to support both sequences for x32.

This patch moves MVE feature bits into the CORE_HIGH section. This makes sure .fpu and -mfpu does not reset the bits set by MVE. This is important because .fpu has no option to "set" these same bits and thus, mimic'ing GCC, we choose to define MVE as an architecture extension rather than put it together with other the legacy fpu features.

2020-01-13[gas][aarch64] Turn on SVE when using f32mm or f64mm extensionsMatthew Malcomson1-0/+5
There are no instructions under these matrix multiply extensions that can be used without having SVE enabled. Since these extensions require SVE, we make that explicit in the options table. Tested on aarch64-none-elf without regressions. gas/ChangeLog: 2020-01-13 Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-aarch64.c (f64mm, f32mm): Add sve as a feature dependency.
