2020-07-08x86: FMA4 scalar insns ignore VEX.LJan Beulich4-0/+110
Just like other VEX-encoded scalar insns do. Besides a testcase for this behavior also introduce one to verify that XOP scalar insns don't honor -mavxscalar=256, as they don't ignore XOP.L.

2020-07-06x86: AVX512 extract/insert insns need to honor EVEX.L'LJan Beulich5-36/+44
Just like their AVX counterparts do for VEX.L. At this occasion also make EVEX.W have the same effect as VEX.W on the printing of VPINSR{B,W}'s operands, bringing them also in sync with VPEXTR{B,W}.
2020-07-06x86: replace EXqScalarS by EXqVexScalarSJan Beulich7-4/+21
There's only a single user, that that one can do fine with the alternative, as the "Vex" aspect of the other operand kind is meaningful only on 3-operand insns. While doing this I noticed that I didn't need to do the same adjustment in the EVEX tables, and voilà - there was a bug, which gets fixed at the same time (see the testsuite changes).

This patch fixes a segfault which occurs when the AArch64 backend parses a symbol operand that begins with a register name and ends with a unicode byte (byte value > 127).

2020-07-01obsolete xc16xAlan Modra2-0/+6
The xc16x md_apply_fix code is just so broken that in my opinion the target should never have been accepted, and from a quick look at commit logs for the target it appears that no one has ever contributed fixes for anything. This target has just been a 14 year burden on global binutils and cgen maintainers. That's not how free software is supposed to work. bfd/ * config.bfd: Obsolete xc16x. gas/ * config/tc-xc16x.c (md_apply_fix): Add FIXME.

2020-06-30RISC-V: Support debug and float CSR as the unprivileged ones.Nelson Chu17-188/+208
The unprivileged CSR should be controlled by other specific specs rather than the privileged spec. For example, the debug CSR should be controlled by the debug spec, and the float CSR should be controlled by the float spec. User may use assembler options to choose what the debug and other specs they want, or may encode the versions of specs into the architecture string directly. Since we haven't decided which one is better, we set the defined and aborted versions of unprivileged CSR to PRIV_SPEC_CLASS_NONE in the include/opcode/riscv-opc.h, to tell assembler don't check priv spec versions for them. However, these PRIV_SPEC_CLASS_NONE will be changed to FLOAT_SPEC_CLASS_* and DEBUG_SPEC_CLASS_* in the future. gas/ * config/tc-riscv.c (riscv_csr_class_check): Removed.

2020-06-25x86: operand sizing prefixes can disambiguate insnsJan Beulich13-447/+1193
Use of an explicit data size or REX.W prefix is sufficient indication of the intended operation when operand size can't be derived from suffix or register operands. Avoid the ambiguity warning and make in particular immediate handling (sizing) cope with explicitly specified prefixes. Extending/reusing the noreg16 test made me notice a few cases of unintentional 32-bit addressing, which gets corrected at the same time.
2020-06-25x86: fix SYSRET disassembly, improve {,V}CVTSI2S{S,D} and PTWRITEJan Beulich17-225/+240
SYSRET can't use the same macro as IRET, since there's no 16-bit operand size form of it. Re-use LQ for it instead. Doing so made obvious that outside of 64-bit mode {,V}CVTSI2S{S,D} and PTWRITE should have an 'l' suffix printed only in suffix-always mode.
2020-06-25x86-64: REX prefix is invalid with VEX etcJan Beulich6-15/+29
Just like for the data size prefix (see commit 7a8655d2bbdc ["x86: don't abort() upon DATA16 prefix on (E)VEX encoded insn"]), any form of REX prefix is invalid with VEX/XOP/EVEX.
2020-06-25x86-64: honor REX prefixes for SSE2AVXJan Beulich4-29/+112
Legacy encoded insns do so, and their automatic conversion to AVX ones ought to produce functionally identical code. Therefore explicit REX prefixes cannot simply be ignored. This is in particular relevant because at least PCMPESTR{I,M}'s 64-bit forms couldn't be expressed in older gas by other than using a REX64 prefix.
2020-06-25x86: also refuse data size prefix on SIMD insnsJan Beulich8-14/+37
The data size prefix alters the meaning of legacy encoded SIMD insns, and hence shouldn't be accepted there. Use of it also leads to inconsistencies in SSE2AVX mode. Don't match insns with data size prefix against SSE2AVX templates.

2020-06-23RISC-V: Generate ELF priv attributes if priv instruction are explicited used.Nelson Chu9-6/+123
We should generate the ELF priv attributes only if, 1. The priv attributes are already set in the assembly file. 2. The CSR are explicited used. 3. The privileged instruction are explicited used. * There are four privileged instruction defined in the v1.11 priv spec: `mret`, `sret`, `wfi` and `sfence.vma`. * `sfence.vm` is dropped in the v1.10 priv spec. * `uret` is actually a N-ext instruction. So it is better to regard it as an user instruction rather than the priv instruction. * `hret` is used to return from traps in H-mode. H-mode is removed since the v1.10 priv spec, but probably be added in the new hypervisor spec. Therefore, `hret` should be controlled by the hypervisor spec rather than priv spec in the future. * `dret` is a debug instruction.

2020-06-22RISC-V: Report warning when linking the objects with different priv specs.Nelson Chu2-27/+15
We do know some conflicts among different privileged specs. For linker, the safest approach is that don't allow the object linked with others which may cause conflicts. But this may cause inconvenience since not all objects with conflicting priv specs are linked will cause problems. But it is hard to know the detailed conflict cases for linker, so we probably need a option to tell linker that we do know there are no conflicts, or we are willing to take risks to link the objects with conflicted priv specs. But the option is still under discussion. Therefore, we can report warnings rather than errors when linking the objects with conflicted priv specs. This not only makes the linker more flexible, but also warns people that the conflicts may happen. We also need to update the output priv spec version once the input priv spec is newer. bfd/ * elfxx-riscv.c (struct priv_spec_t priv_specs[]): Move them from opcodes/riscv-opc.c to bfd/elfxx-riscv.c, since we need it in linker.

2020-06-12RISC-V: Drop the privileged spec v1.9 support.Nelson Chu4-298/+6
There is a conflict between v1.9 and v1.9.1 - CSR MISA address. MISA is 0xf10 in v1.9, but change to 0x301 in v1.9.1. The change made MISA writable, but may also cause risk of compatibility. Binutils already support the -mpriv-spec options and ELF priv attributes, which can used to choose what privileged spec you want, and then give a correponding CSR name and address to use. But Gdb and other tools don't have the simialr mechanism for now. However, there are two things can be confirmed, 1. If we don't have a way to control the priv specs, then the changes, like MISA, will cause risk and hard to maintain. 2. We get the guarantee that the CSR address won't be reused in the future specs, even if it is dropped. I'm not sure if Gdb needs to care about the priv spec versions, it is still discussing. But drop the priv spec v1.9, and make sure that we won't reuse the CSR address is a useful solution for now. Also, we might drop the v1.9.1 in a year or two. After that, specs above v1.10 should be compatible anyway. gas/ * testsuite/gas/riscv/priv-reg-fail-version-1p9.d: Removed. * testsuite/gas/riscv/priv-reg-fail-version-1p9.l: Likewise. * testsuite/gas/riscv/priv-reg-version-1p9.d: Likewise. include/ * opcode/riscv-opc.h: Update the defined versions of CSR from PRIV_SPEC_CLASS_1P9 to PRIV_SPEC_CLASS_1P9P1.
