2018-03-08x86: fold several AVX512VL templatesJan Beulich2-6/+47
The differences between some of the register and memory forms of the same insn often don't really require the templates to be separate. For example, Disp8MemShift is simply irrelevant to register forms. Fold these as far as possible, and also fold register-only forms. Further folding is possible, but needs other prereq work done first. A note regarding EVEXDYN: This is intended to be used only when no other properties of the template would make is_evex_encoding() return true. In all "normal" cases I think it is preferable to omit this indicator, to keep the table half way readable.
2018-03-08x86: fold certain AVX512 rotate and shift templatesJan Beulich2-3/+9
Their memory forms were bogusly using VexLWP instead of VexNDD. Adjust VexNDD handling to cope with these, allowing their register and memory forms to be folded.
2018-03-08x86: drop {X,Y,Z}MMWORD_MNEM_SUFFIXJan Beulich3-43/+32
They aren't really useful (anymore?): The conflicting operand size check isn't applicable to any insn validly using respective memory operand sizes (and if they're used wrongly, another error would result), and the logic in process_suffix() can be easily changed to work without them. While re-structuring conditionals in process_suffix() also drop the CMPXCHG8B special case in favor of a NoRex64 attribute in the opcode table.
2018-03-08x86: correct operand size match checks for BMI/BMI2 insnsJan Beulich5-7/+64
Some BMI/BMI2 insns allow their middle operands to be a memory one. In such a case, matching register types between operands 0 and 1 as well as 1 and 2 won't help - operands 0 and 2 also need to be checked.
2018-03-08x86: fold redundant expressions in process_suffix()Jan Beulich2-20/+18
There's no point repeatedly evaluating i.types[op].bitfield.reg.
2018-03-08x86: simplify result processing of cpu_flags_match()Jan Beulich2-24/+21
Make more obvious what the success and failure paths are, and in particular that what used to be at the "skip" label can't be reached by what used to be straight line code.
2018-03-08x86: add GFNI, VAES, and VPCLMUL checking to cpu_flags_match()Jan Beulich19-2/+177
Just like for the AVX/AES and AVX/PCLMUL combinations, AVX/GFN, AVX512F/GFNI, AVX512F/VAES, and AVX512F/PCLMUL need special handling to deal with the pair of required checks specified in the templates.
2018-03-08x86: change AVX512VL handling in cpu_flags_match()Jan Beulich2-11/+9
In order to add an AVX512F counterpart to the present AVX checking, it is better to move the AVX512VL check out of the conditional it's currently in.
2018-03-08x86: drop CPU_FLAGS_32BIT_MATCHJan Beulich2-5/+10
It has become a plain alias of CPU_FLAGS_ARCH_MATCH now.
2018-03-08x86: simplify AVX checks in cpu_flags_match()Jan Beulich2-22/+14
No caller cares about the specifics of CPU_FLAGS_{AES,AVX,PCLMUL}_MATCH, so drop those and fold the nested if()-s.
2018-03-08x86: avoid cpu_flags_match() bogusly setting CPU_FLAGS_ARCH_MATCHJan Beulich2-6/+5
2018-03-08x86: extend SSE check to PCLMULQDQ, AES, and GFNI insnsJan Beulich16-126/+88
When aiming at not mixing SSE and AVX insns, these should be warned about the same way other non-AVX ones are treated.
2018-03-08x86: drop FloatDJan Beulich2-7/+12
It can be expressed by D, when making the consumer look at operand size to tell apart both uses.
2018-03-08x86/Intel: correct disassembly of fsub*/fdiv*Jan Beulich3-0/+716
fsub/fsubr/fsubp/fsubrp as well as fdiv/fdivr/fdivp/fdivrp disassembly should match (a) the Intel SDM and (b) respective input fed to gas (both of course with the exception of when we intentionally convert bogus insns, accompanied by a warning).
2018-03-08x86: adjust 4-XMM-register-group related warningJan Beulich4-30/+39
Drop "second": For one there's no other source register (the other source operand is in memory), and in Intel syntax such numbering would also be wrong. Take the opportunity and also - properly place declarations ahead of statements - use %u format for unsigned int arguments - fix indentation
2018-03-08x86: bogus VMOVD with 64-bit operands should only allow for registersJan Beulich4-6/+6
These templates exist solely to satisfy gcc's needs, and gcc only produces these with register operands.
2018-03-08x86: fold AVX vcvtpd2ps memory formsJan Beulich2-10/+42
This requires a change to ModR/M handling: Recording of displacement types must not discard operand size information. Change the respective code to alter only .disp<N>.
2018-03-08Really remove unnecessary power9 group terminating nopAlan Modra2-4/+8
Oops, not tested well enough. -mpower9 sets all the PPC_OPCODE_POWERn for n <= 9. * config/tc-ppc.c (ppc_handle_align): Correct last patch. Really don't emit a group terminating nop for power9. Simplify cpu tests.
2018-03-08Remove unnecessary power9 group terminating nopAlan Modra2-10/+13
Power9 doesn't have a group terminating nop, so we may as well emit a normal nop for power9. Not that it matters a great deal, I believe ori 2,2,0 will be treated exactly as ori 0,0,0 by the hardware. * config/tc-ppc.c (ppc_handle_align): Don't emit a group terminating nop for power9.
2018-03-07x86: Rewrite NOP generation for fill and alignmentH.J. Lu65-3363/+2392
Rewrite NOP generation for fill and code alignment by: 1. Add a 11-byte NOP with another 0x66 prefix. 2. Remove the multi-byte NOP entries which consist of 2 instructions. 3. Select proper NOPs based on ISA and processor tuning. 4. Generate multiple NOPs with the longer NOPs first followed by the shorter NOP. 5. Use jump for larger NOP padding: a. > 8 bytes (2 NOPs) in 16-bit mode. b. > 14 bytes (2 NOPs) for older processors. c. > 77 bytes (7 NOPs) for newer processors. 6.

2018-03-01[ARM] Clean up selection of feature bitsThomas Preud'homme2-111/+171
I've always found the code in ARM backend of gas to control what CPU/architecture and FPU are selected by the user and to support autodetection of features complex and confusing. Chief among the issues I have with that code is the lack of comments to explain the meaning of the various variables. This patch addresses that and much more: - add comments to explain meaning of all arm_feature_set variables - keep track of currently selected CPU, extensions and FPU in a separate set of new variables - make naming of variable more consistent - remove dead code - simplify handling of extensions The overall approach is as follows: * restrict m*_opt variable to hold the feature bits of the corresponding mcpu/march/mfpu command-line options * record selected CPU, extensions and FPU in new selected_* during md_begin * whenever a .cpu/.arch/.arch_extension/.fpu directive is met, update the corresponding selected_* variables (eg. selected_arch, then selected_cpu for a .cpu or .arch directive) and then finally cpu_variant from them * pass extension feature set pointer by value to arm_parse_extension since it's only ever called from arm_parse_cpu and arm_parse_arch which allocate the extension feature set themselves * likewise, remove allocation from s_arm_arch_extension since the use of arm_feature_set structure for selected_ext rather than a pointer alleviate the need for it * in autodetection mode, only set all CPU fits in cpu_variant but leave selected_cpu* variables unset * in md_begin, remove dead "else if" to set a default FPU when no FPU was selected. Setting a default FPU based on CPU as did the code before it turn dead should be based on the default FPU field of the CPU and architecture table as will be done in a separate patch. Logic is wrong anyway since it sets VFP2 as default FPU for Armv6-M and Armv7-M Hopefully that should be enough to understand the change but if not feel free to ask questions about the patch. While I believe the new code is easier to understand, it remains complex and the old one was even more complex so the change is difficult to understand. 2018-03-01 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (cpu_variant, arm_arch_used, thumb_arch_used, legacy_cpu, legacy_fpu, mcpu_cpu_opt, dyn_mcpu_ext_opt, mcpu_fpu_opt, march_cpu_opt, dyn_march_ext_opt, march_fpu_opt, mfpu_opt, object_arch, selected_cpu): Comment meaning of variables.

2018-02-27x86: Add -O[2|s] assembler command-line optionsH.J. Lu21-2/+773
On x86, some instructions have alternate shorter encodings: 1. When the upper 32 bits of destination registers of andq $imm31, %r64 testq $imm31, %r64 xorq %r64, %r64 subq %r64, %r64 known to be zero, we can encode them without the REX_W bit: andl $imm31, %r32 testl $imm31, %r32 xorl %r32, %r32 subl %r32, %r32 This optimization is enabled with -O, -O2 and -Os. 2. Since 0xb0 mov with 32-bit destination registers zero-extends 32-bit immediate to 64-bit destination register, we can use it to encode 64-bit mov with 32-bit immediates. This optimization is enabled with -O, -O2 and -Os. 3. Since the upper bits of destination registers of VEX128 and EVEX128 instructions are extended to zero, if all bits of destination registers of AVX256 or AVX512 instructions are zero, we can use VEX128 or EVEX128 encoding to encode AVX256 or AVX512 instructions. When 2 source registers are identical, AVX256 and AVX512 andn and xor instructions: VOP %reg, %reg, %dest_reg can be encoded with VOP128 %reg, %reg, %dest_reg This optimization is enabled with -O2 and -Os. 4. 16-bit, 32-bit and 64-bit register tests with immediate may be encoded as 8-bit register test with immediate. This optimization is enabled with -Os. This patch does: 1. Add {nooptimize} pseudo prefix to disable instruction size optimization. 2. Add optimize to i386_opcode_modifier to tell assembler that encoding of an instruction may be optimized. gas/ PR gas/22871 * NEWS: Mention -O[2|s]. * config/tc-i386.c (_i386_insn): Add no_optimize.
