2025-01-14ld: Update mixed LTO and non-LTO relocatable output testsH.J. Lu1-40/+42
Since mixed LTO and non-LTO relocatable output is only supported on ELF platforms, limit these tests to ELF targets. Since powerpc64 elfv1 defines a function symbol on its procedure descriptor, which is in a data section, rather than on the code for that function, allow both D and T for nm test on mixed object. * testsuite/ld-plugin/lto.exp: Limits mixed LTO and non-LTO relocatable output tests to ELF targets. Allow both D and T for nm test on mixed object. Signed-off-by: H.J. Lu <hjl.tools@gmail.com>
2025-01-14aarch64 SFrame: skip with warning new CFI directive used with pauth_lrMatthieu Longo4-0/+65
Today, SFrame v2 specification does not describe how to encode the information corresponding to the PAuth_LR PAC signing method (it only supports PAuth PAC signing method). SFrame v3 specification should hopefully specify it. In the meantime, if the GNU assembler finds .cfi_negate_ra_state_with_pc and --gsframe is specified, it will output a warning to the user and will fail to generate the FDE entry. A new SFrame test for .cfi_negate_ra_state_with_pc is also added to reflect this issue. Approved-by: Indu Bhagat <indu.bhagat@oracle.com>
2025-01-14aarch64 DWARF: add new CFI directive for PAuth_LRMatthieu Longo5-1/+22
This patch adds a new CFI directive (cfi_negate_ra_state_with_pc) which set an additional bit in the RA state to inform that RA was signed with SP but also PC as an additional diversifier. RA state | Description 0b00 | Return address not signed (default if no cfi_negate_ra_state*) 0b01 | Return address signed with SP (cfi_negate_ra_state) 0b10 | Invalid state 0b11 | Return address signed with SP+PC (cfi_negate_ra_state_with_pc) Approved-by: Indu Bhagat <indu.bhagat@oracle.com> Approved-by: Jan Beulich <jbeulich@suse.com>
2025-01-14aarch64 SFrame: use preferred CFI directive for AArch64 PACMatthieu Longo4-4/+51
ARMv8.3 addded support for a new security feature named Pointer Authentication. Support for this feature in SFrame already exists. In GCC 14 and older, the Sparc DWARF extension .cfi_gnu_window_save is emitted instead of .cfi_negate_ra_state. GCC 15 fixed this issue, but this behavior is preserved for backward compatibility. The existing sframe test for AArch64 PAC was using .cfi_gnu_window_save. This patch replaces this CFI in the existing test by the preferred one, and adds a new test to check for backward compatibility when using .cfi_gnu_window_save.

2025-01-14aarch64: make explicit that CFI gnu_window_save is for Sparc, not AArch64Matthieu Longo4-3/+73
- add a detailed comment when parsing DW_CFA_GNU_window_save in SFrame to explain why we are checking whether the targeted architecture is AArch64, whereas this CFI is a Sparc extension. - replace .cfi_gnu_window_save by .cfi_negate_ra_state in existing AArch64 DWARF tests as this is the preferred directive since GCC 15. - add a new AArch64 test to check backward compatibility with old GCC versions that emits .cfi_gnu_window_save.

2025-01-14gdbserver: remove handling of the 'L' tracepoint actionTankut Baris Aktemur1-46/+0
Now that static tracepoint support is removed from gdbserver, it makes sense to remove handling of the 'L' tracepoint action, too. The code that checks received actions already has a default case that tolerates unrecognized actions: default: trace_debug ("unknown trace action '%c', ignoring...", *act); In case 'L' is unexpectedly received, we would at least be able to see this in the logs.

2025-01-14gdbserver: remove the static_tracepoint enum valueTankut Baris Aktemur1-143/+36
As a continuation of the previous patches that remove UST from gdbserver, remove the `static_tracepoint` enum value from `tracepoint_type` and all the associated code. Now that the last use of `write_e_static_tracepoints_not_supported` is gone, also remove that function. The handling of the 'S' option, where the `static_tracepoint` enum value was being used, is removed completely, because recognizing that option makes sense only when static tracepoint support is announced. This patch is easier to view with "git show -w". Approved-By: Simon Marchi <simon.marchi@efficios.com>
2025-01-14gdbserver: do not announce static tracepoint supportTankut Baris Aktemur3-125/+0

2025-01-14gdbserver: remove UST (static tracepoint) support (part 1)Tankut Baris Aktemur9-901/+6
UST support in gdbserver is substantially outdated. Simon says: ...[having HAVE_UST defined] never happens nowadays because it used a version of lttng-ust that has been deprecated for a loooong time (the 0.x series). So everything in HAVE_UST just bitrots. It might be possible to update all this code to use lttng-ust 2.x (1.x never existed), but I don't think it's going to happen unless somebody specifically asks for it. I would suggest removing support for UST from gdbserver. ...If we ever want to resurrect the support for UST and port to 2.x, we can get the code from the git history. This patch removes the support, mostly mechanically by deleting code guarded by `#ifdef HAVE_UST`. After these removals, `struct static_tracepoint_ctx` becomes unused. So, remove it, too. The following patches remove more code. Reviewed-By: Eli Zaretskii <eliz@gnu.org> Approved-By: Simon Marchi <simon.marchi@efficios.com>

2025-01-14gdb, doc: mention the 'S' option for the QTDP packetTankut Baris Aktemur1-2/+3
I noticed that gdbserver accepts an 'S' option for the QTDP packet to create a static tracepoint, but this is not mentioned in the document. Update the document. I first thought about updating the argument as `[:Flen|:S]`, but then opted for `[:Flen][:S]`. Although it is odd that ':F' and ':S' are allowed to co-exist, the implementation at the gdbserver side allows this and handles the packet arguments so that the right-most positioned ':F' or ':S' overwrites the final tracepoint type. When the documentation is missing, the implementation usually determines the behavior. Reviewed-By: Eli Zaretskii <eliz@gnu.org>

2025-01-14x86: Remove "NE" in mnemonics for convert insns related to AI data typesHaochen Jiang28-2893/+2893
NE is quite ambiguous and misleading in mnemonics since it should be Rounding to Nearest Even, but could be mis-interpretated to No Exception. Under its correct meaning, which means rounding, it should only be used in down-convert, since up-convert is always exact for normal values It could be difficult to judge which kind of convert it is if we have the convert between same bit float types. For all AI data types including BF16 and FP8, the default rounding is Rounding to Nearest Even. So removing them in mnemonics would reduce burden for programmers to consider whether it should be added or not in mnemonics and stop the ambiguous meaning on "NE" itself. If the convert itself is using a rounding mode other than RNE, it would be explicitly added in mnemonics (e.g., Long used "T" and "BIAS" introduced in AVX10.2). gas/ChangeLog: * testsuite/gas/i386/avx10_2-256-cvt-intel.d: Refine testcases according to mnemonics change. * testsuite/gas/i386/avx10_2-256-cvt.d: Ditto. * testsuite/gas/i386/avx10_2-256-cvt.s: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-256-satcvt.s: Ditto. * testsuite/gas/i386/avx10_2-512-cvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-512-cvt.d: Ditto. * testsuite/gas/i386/avx10_2-512-cvt.s: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt-intel.d: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/avx10_2-512-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-cvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-256-satcvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-cvt.s: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt-intel.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.d: Ditto. * testsuite/gas/i386/x86-64-avx10_2-512-satcvt.s: Ditto. opcodes/ChangeLog: * i386-dis-evex-prefix.h: Remove ne in mnemonics for convert insns. * i386-opc.tbl: Ditto. * i386-mnem.h: Regenerated. * i386-tbl.h: Ditto.

2025-01-14x86: Remove "P" and "NE" in mnemonics for BF16 arithmetic insnsHaochen Jiang28-4386/+4386
Since the bf16 is an AI data types, it will be implicitly packed. Thus, "P" (for packed) is omitted in mnemonics from its introduction. AVX10.2 BF16 arithmetic insns are introduced with "P" in mnemonics with packed. This patch will remove them for consistency. NE is quite ambiguous and misleading in mnemonics since it should be Rounding to Nearest Even, but could be mis-interpretated to No Exception. While AI data types like BF16 and FP8 are using Rounding to Nearest Even as default rounding modes. There is no need to use the ambiguous mnemonics in AVX10.2 insns. This patch will also remove them.

2025-01-14Support Intel AMX-MOVRSHu, Lin123-2625/+3020
This patch will support AMX-MOVRS feature. Unlike all the other AMX insns in vector space where we pass vex_len_table before vex_w_table, we first pass vex_w_table for tileloaddrs[,t1] to align with the order in EVEX space. The reason why we first pass vex_w_table in EVEX space is due to AMX-AVX512, where tcvtrowd2ps and tilemovrow with r32 shares the same opcode with tileloaddrs[,t1]. All of them have evex.w = 0 but with different evex.length. Re-doing that shortly is not ideal. APX_F extension is also implemented in this patch. The encoding will be: - EVEX.128.NP/66.MAP5.W0 F8/F9 !(11):rrr:100 for T2RPNTLVW[Z0,Z1]RS[,T1] with NF=0. - EVEX.128.F2/66.0F38.W0 4A !(11):rrr:100 FOR TILELOADDRS[,T1] with NF=0. For APX_F extension, we could not use APX_F(AMX_TRANSPOSE&AMX_MOVRS) since the transformation could not be done. Instead, we will use AMX_TRANSPOSE & APX_F(AMX_MOVRS). Thus, we should set AMX_TRANSPOSE for "any" for cpu_flags in assembler. Since it will only affect the cpu_flags_match, handle that there. gas/ChangeLog: * config/tc-i386.c (cpu_arch): Add amx_movrs.

2025-01-14x86: Remove mod_table pass for MVexSIBMEMHaochen Jiang1-28/+18
When using MVexSIBMEM, OP_M will help check modrm. Thus, no need to pass mod_table. Since we have OP_M do the work, from now on, mod_table[] should not gain any new entries, unless both slots of them are populated, e.g., different modrm leading to different insns could not be combined (Bad_Opcode is not the case since OP_M could handle that). opcodes/ChangeLog: * i386-dis.c: Remove mod_table pass for MVexSIBMEM.

While we don't want to revert back to original behavior, apply the same alignment "capping" as done originally in two other places also for "ordinary" sections.

This results in an array view of size 1. The assertion in `frame_register_unwind` that verifies the passed in buffer is larger enough to hold the unwound register value then fails. Fix this by explicitly creating an array view of the right size. Change-Id: Ie170da438ec9085863e7be8b455a067b531635dc Reviewed-by: Thiago Jung Bauermann <thiago.bauermann@linaro.org>

2025-01-12Add an option with a color type.Andrei Pikas34-172/+2437
Colors can be specified as "none" for terminal's default color, as a name of one of the eight standard colors of ISO/IEC 6429 "black", "red", "green", etc., as an RGB hexadecimal tripplet #RRGGBB for 24-bit TrueColor, or as an integer from 0 to 255. Integers 0 to 7 are the synonyms for the standard colors. Integers 8-15 are used for the so-called bright colors from the aixterm extended 16-color palette. Integers 16-255 are the indexes into xterm extended 256-color palette (usually 6x6x6 cube plus gray ramp). In general, 256-color palette is terminal dependent and sometimes can be changed with OSC 4 sequences, e.g. "\033]4;1;rgb:00/FF/00\033\\". It is the responsibility of the user to verify that the terminal supports the specified colors. PATCH v5 changes: documentation fixed. PATCH v6 changes: documentation fixed.

2025-01-10GDB: Use gdb::array_view for buffers used in register reading and unwindingThiago Jung Bauermann4-39/+48
This allows checking the size of the given buffer. Changes frame_register_unwind (), frame_unwind_register (), get_frame_register () and deprecated_frame_register_read (). As pointed out by Baris, in the case of MIPS target code this is best done by changing a couple of alloca-based buffers in mips_read_fp_register_single and mips_print_fp_register to gdb::byte_vector instances.

2025-01-10GDB: frame: Make VALUEP argument optional in frame_register_unwindThiago Jung Bauermann3-5/+5
It already accepts a nullptr value and a couple of places were always calling it that way, so make it possible to omit the argument entirely. Approved-By: Simon Marchi <simon.marchi@efficios.com>
