2019-07-09Re: gas/ELF: don't accumulate .type settingsAlan Modra5-29/+42
git commit f2d4ba38f5 caused many failures for mips-sgi-irix targets, and added a new test that failed for aarch64, nds32, and rl78. The mips failures are due to BSF_OBJECT being set in many cases for symbols by the mips .global/.globl directive. This patch removes that code and instead sets BSF_OBJECT in a target frob_symbol function, also moving the mips hacks in elf_frob_symbol to the new function. Note that common symbols are handled fine in elf.c:swap_out_syms without needing to set BSF_OBJECT, so that old code can disappear. * config/obj-elf.c (elf_frob_symbol): Remove mips hacks. * config/tc-mips.h (tc_frob_symbol): Define.

2019-07-04x86: correct "-Q" option handlingJan Beulich2-1/+9
For another patch I wanted to use a sufficiently benign option (simply to be able to specify one, which certain test case invocations require), and I stumbled across -Q in the --help output. Before realizing that this is x86-specific anyway, I've tried and and ran into a mysterious testsuite failure, until I further realized that other than the help text suggests the option requires an argument. Correct the help text, and make the implementation actually match what the comment there has been describing (and what the help text now says).
2019-07-04gas/ELF: don't accumulate .type settingsJan Beulich8-1/+118
Recently a patch was submitted for a Xen Project test harness binary to override the compiler specified @object to @func (see [1]). In a reply I suggested we shouldn't make ourselves dependent on currently unspecified behavior of gas here: It accumulates all requests, and then bfd/elf.c:swap_out_syms(), in an apparently ad hoc manner, prioritizes certain flags over others. Make the behavior predictable: Generally the last .type is what counts. Exceptions are directives which set multiple bits (TLS, IFUNC, and UNIQUE): Subsequent directives requesting just the more generic bit (i.e. FUNC following IFUNC) won't clear the more specific one. Warn about incompatible changes, except from/to STT_NOTYPE. Also add a new target hook, which hppa wants to use right away afaict. In the course of adding the warning I ran into two ld testsuite failures. I can only assume that it was a copy-and-paste mistake that lead to the same symbol having its type set twice.

2019-07-02This patch fixes a bug in the AArch64 assembler where an incorrect ↵Barnaby Wilks6-1/+29
structural load/store by element instruction would generate the wrong error message. For example, when provided with the (incorrect) instruction st4 {v0.16b-v3.16b}[4],[x0] currently assembler provides the following error message "Error: comma expected between operands at operand 2 -- `st4 {v0.16b-v3.16b}[4],[x0]'". This was due to the assembler consuming the {v0.16b-v3.16b} as the first operand leaving [4],[x0] as what it believed to be the second operand. The actual error is that the first operand should be of element type and not vector type (as provided). The new diagnostic for this error is "Error: expected element type rather than vector type at operand 1 -- `st4 {v0.16b-v3.16b}[4],[x0]'. Added testcases to check for the correct diagnostic message as well as checking that variations of the structural load/store by element instruction also generate the error when they have the same problem. * config/tc-aarch64.c (parse_operands): Add error check. * testsuite/gas/aarch64/diagnostic.l: New test. * testsuite/gas/aarch64/diagnostic.s: New test. * testsuite/gas/aarch64/illegal.l: New tests. * testsuite/gas/aarch64/illegal.s: New tests.

2019-07-01[gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AESMatthew Malcomson7-11/+43
I had mistakenly given all variants of the new SVE2 instructions pmull{t,b} a dependency on the feature +sve2-aes. Only the variant specifying .Q -> .D sizes should have that restriction. This patch fixes that mistake and updates the testsuite to have extra tests (matching the given set of tests per line in aarch64-tbl.h that the rest of the SVE2 tests follow). We also add a line in the documentation of the command line to clarify how to enable `pmull{t,b}` of this larger size. This is needed because all other instructions gated under the `sve2-aes` architecture extension are marked in the instruction documentation by an `HaveSVE2AES` check while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.

2019-07-01x86: drop Vec_Imm4Jan Beulich2-25/+19
It is pretty wasteful to have a per-operand flag which is used in exactly 4 cases. It can be relatively easily replaced, and by doing so I've actually found some dead code to remove at the same time (there's no case of ImmExt set at the same time as Vec_Imm4).
2019-07-01x86: limit ImmExt abuseJan Beulich2-13/+17
In quite a few cases ImmExt gets used when there's not really any immediate, but rather a degenerate ModR/M byte. ENCL{S,U} show how this case is supposed to be dealt with. Eliminate most abuses, leaving in place (for now) only ones where process_immext() is involved.
2019-07-01x86: optimize AND/OR with twice the same registerJan Beulich10-1/+435
It seems to be not uncommon for people to use AND or OR in this form for just setting the status flags. TEST, which doesn't write to any register other than EFLAGS, ought to be preferred. Make the change only for -O2 and above though, at least for now.
2019-07-01x86-64: optimize certain commutative VEX-encoded insnsJan Beulich14-1246/+1048
When they're in the 0F opcode space, swapping their source operands may allow switching from 3-byte to 2-byte VEX prefix encoding. Note that NaN behavior precludes us doing so for many packed and scalar floating point insns; such an optimization would need to be done by the compiler instead in this case, when it knows that NaN-s have undefined behavior anyway. While for explicitly specified AVX/AVX2 insns the optimization (for now at least) gets done only for -O2 and -Os, it is utilized by default in SSE2AVX mode, as there we're re-writing the programmer's specified insns anyway. Rather than introducing a new attribute flag, the change re-uses one which so far was meaningful only for EVEX-encoded insns.
2019-07-01x86: StaticRounding implies SAEJan Beulich2-6/+8
This implication allows to simplify some conditionals, thus slightly improving performance. This change also paves the way for re-using StaticRounding for non-EVEX insns.
2019-07-01x86: optimize EVEX packed integer logical instructionsJan Beulich24-17/+955
As long as there's no write mask as well as no broadcast, and as long as the scaled Disp8 wouldn't result in a shorter EVEX encoding, encode VPAND{D,Q}, VPANDN{D,Q}, VPOR{D,Q}, and VPXOR{D,Q} acting on only the lower 16 XMM/YMM registers using their VEX equivalents with -O1. Also take the opportunity and avoid looping twice over all operands when dealing with memory-with-displacement ones.
2019-07-01x86: add missing pseudo ops for VPCLMULQDQ ISA extensionJan Beulich19-18/+145
While the ISA extensions doc suggests them to be made available just like the SDM does for the PCLMULQDQ ISA extension, these weren't added when supposrt for the new extension was introduced. Also make sure the 64-bit non-AVX512 test actually tests VEX encodings, not EVEX ones.

4 bits (0xF) could be passed to the SMC (Secure Monitor Call) instruction. For example, this code is invalid: smc #0x6951 The code would previously check for and encode for up to 16 bit immediate values, however this immediate should instead be only a 4 bit value (as documented herehttps://static.docs.arm.com/ddi0406/c/DDI0406C_C_arm_architecture_reference_manual.pdf ).

2019-06-27x86: allow VEX et al encodings in 16-bit (protected) modeJan Beulich15-4/+16793
These encodings aren't valid in real and VM86 modes, but they are very well usable in 16-bit protected mode. A few adjustments in the disassembler tables are needed where Ev or Gv were wrongly used. Additionally an adjustment is needed to avoid printing "addr32" when that's already recognizable by the use of %eiz. Furthermore the Iq operand template was wrong for XOP:0Ah encoding insns: They're having a uniform 32-bit immediate. Drop Iq and introduce Id instead. Clone a few existing test cases to exercise assembler and disassembler.

When MTHC1 instruction is paired with MTC1 to write a value to a 64-bit FPR, the MTC1 must be executed first, because the semantic definition of MTC1 is not aware that software will be using an MTHC1 to complete the operation, and sets the upper half of the 64-bit FPR to an UNPREDICTABLE value[1].

2019-06-25x86: correct / adjust debug printingJan Beulich2-9/+19
For quite some time we've been using combinations of bits for specifying various registers in operands and templates. I think it was Alan who had indicated that likely the debug printing would need adjustment as a result. Here we go. Accumulator handling for GPRs gets changed to match that for FPU regs. For this to work, OPERAND_TYPE_ACC{32,64} get repurposed, with their original uses replaced by direct checks of the two bits of interest, which is cheaper than operand_type_equal() invocations. For SIMD registers nothing similar appears to be needed, as respective operands get stripped from the (copy of the) template before pt() is reached. The type change on pi() is to silence a compiler diagnostic. Arguably its other parameter could also be const-qualified.
