2020-01-21x86: replace adhoc ambiguous operand checking for CRC32Jan Beulich13-50/+60
There's no need (anymore?) to heavily special case this - just make generic logic consider only its first operand, and deal with the case of an 'l' suffix not being allowed in a pattern.
2020-01-21x86: improve handling of insns with ambiguous operand sizesJan Beulich49-130/+1075
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 Beulich8-8/+40
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.

2020-01-20x86-64: Fix TLSDESC relaxation for x32H.J. Lu23-21/+579
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. For both GDesc -> IE/LE transitions, 67 ff 10 call *x@TLSCALL(%eax) should relaxed to 0f 1f 00 nopl (%rax) For GDesc -> LE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg For GDesc -> IE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 8b 05 00 00 00 00 rex movl x@gottpoff(%rip), %eax bfd/ PR ld/25416 * elf64-x86-64.c (elf_x86_64_check_tls_transition): Support "rex leal x@tlsdesc(%rip), %reg" and "call *x@tlsdesc(%eax)" in X32 mode.

2020-01-19sim: don't rely on inferior_ptid in gdbsim_target::waitSimon Marchi2-1/+6
When running a program with the simulator target, I get: /home/simark/src/binutils-gdb/gdb/inferior.c:279: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed. This can be reproduced by building a GDB for --target=arm-none-gnueabi, and running with $ ./gdb -nx --data-directory=data-directory a.out -ex "target sim" -ex load -ex "b main" -ex r Where a.out is any program with a main. The problem is that gdbsim_target::wait assumes that inferior_ptid has the value of the thread it wants to report an event for. Actually, it's the target's responsibility to come up with the ptid of the thread the event is for. In the sim target, that ptid is stored in sim_inferior_data::remote_sim_ptid, so return that instead of inferior_ptid. ChangeLog: * remote-sim.c (gdbsim_target::wait): Return sim_data->remote_sim_ptid instead of inferior_ptid.

Use range-based for instead of iterate_over_inferiors in one spot in the Python code. gdb/ChangeLog: * python/py-inferior.c (build_inferior_list): Remove. (gdbpy_ref): Use range-based for loop to iterate over inferiors.

2020-01-16Support for DWARF5 location lists entriesNitika Achra2-0/+44
This patch handles DW_LLE_base_addressx, DW_LLE_startx_length and DW_LLE_start_length. Tested by running the testsuite before and after the patch and there is no increase in the number of test cases that fails. Tested with both -gdwarf-4 and -gdwarf-5 flags. Also tested -gslit-dwarf along with -gdwarf-4 as well as -gdwarf5 flags. This is an effort to support DWARF5 in gdb. gdb/ChangeLog: * dwarf2loc.c (decode_debug_loclists_addresses): Handle DW_LLE_base_addressx, DW_LLE_startx_length, DW_LLE_start_length.
2020-01-16[binutils][arm] PR25376 Change MVE into a CORE_HIGH featureAndre Vieira6-243/+275
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. This will enable the following behavior: .arch armv8.1-m.main .arch mve .fpu fpv5-sp-d16 #does not disable mve. vadd.i32 q0, q1, q2 This patch also makes sure MVE is not taken into account during auto-detect. This was already the case, but because we moved the MVE bits to the architecture feature space we must make sure ARM_ANY does not include MVE. gas/ChangeLog: 2020-01-16 Andre Vieira <andre.simoesdiasvieira@arm.com> PR 25376 * config/tc-arm.c (mve_ext, mve_fp_ext): Use CORE_HIGH.
