This conventionis used by GAS in similar contexts already,e.g. [1]: Note on targets where the @ character is the start of a comment (eg ARM) then another character is used instead. For example the ARM port uses the % character.In practice, this unfortunately means that all such .seh_handlerdirectives will need ifdefs for ARM.Contrary to ARM64, on ARM, it's quite common that we can't evaluatee.g. the function length at this point, due to instructions whoselength is finalized later. (Also, inline jump tables end witha ".p2align 1".)If unable to to evaluate the function length immediately, emitit as an MCExpr instead. If we'd implement splitting the unwindinfo for a function (which isn't implemented for ARM64 yet either),we wouldn't know whether we need to split it though.Avoid calling getFrameIndexOffset() on an unsetFuncInfo.UnwindHelpFrameIdx, to avoid triggering asserts in thepreexisting testcase CodeGen/ARM/Windows/wineh-basic.ll. (OnceMSVC exception handling is fully implemented, those changescan be reverted.)[1] https://sourceware.org/binutils/docs/as/Section.html#SectionDifferential Revision: https://reviews.llvm.org/D125645 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Thu, 11 Nov 2021 10:06:49 +0000 Martin Storsjö <martin@martin.st> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#051deb2d [ARM] add Armv9 build attributeThe build attribute number can be found in the Arm ABI addenda32 document:https://github.com/ARM-software/abi-aa/blob/main/addenda32/addenda32.rst#335target-related-attributesReviewed By: tmathesonDifferential Revision: https://reviews.llvm.org/D124090 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Thu, 28 Apr 2022 09:23:54 +0000 Ties Stuij <ties@stuij.se> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#b430782b [ARM] emit PACBTI-M build attributesThis patch is part of a series that adds support for the PACBTI-M extension ofthe Armv8.1-M architecture, as detailed here:https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/armv8-1-m-pointer-authentication-and-branch-target-identification-extensionThe PACBTI-M specification can be found in the Armv8-M Architecture ReferenceManual:https://developer.arm.com/documentation/ddi0553/latestThe following people contributed to this patch:- Victor Campos- Ties StuijReviewed By: ostannardDifferential Revision: https://reviews.llvm.org/D112425 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Wed, 01 Dec 2021 10:52:31 +0000 Ties Stuij <ties.stuij@arm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#ad253446 [MC][CodeGen] Emit constant pools earlierPreviously we would emit constant pool entries for ldr inline asm at thevery end of AsmPrinter::doFinalization().

This is good, but there was an oversight in theimplementation: the behavior of VFPv2 was changed. In particular, the"vfp2" feature was changed to imply "d32". This is wrong: VFPv2 onlysupports 16 D registers.In practice, this means if you specify -mfpu=vfpv2, the compiler willgenerate illegal instructions.This patch gets rid of "vfp2d16" and "vfp2d16sp", and fixes "vfp2" and"vfp2sp" so they don't imply "d32".Differential Revision: https://reviews.llvm.org/D67375llvm-svn: 372186 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Tue, 17 Sep 2019 21:42:38 +0000 Eli Friedman <efriedma@quicinc.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#930dee2c [ARM] add target arch definitions for 8.1-M and MVEThis adds:- LLVM subtarget features to make all the new instructions conditional on,- CPU and FPU names for use on clang's command line, with default FPUs set so that "armv8.1-m.main+fp" and "armv8.1-m.main+fp.dp" will select the right FPU features,- architecture extension names "mve" and "mve.fp",- ABI build attribute support for v8.1-M (a new value for Tag_CPU_arch) and MVE (a new actual tag).Patch mostly by Simon Tatham.Differential Revision: https://reviews.llvm.org/D60698llvm-svn: 362090 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Thu, 30 May 2019 12:57:04 +0000 Sjoerd Meijer <sjoerd.meijer@arm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#760df47b [ARM] Replace fp-only-sp and d16 with fp64 and d32.Those two subtarget features were awkward because their semantics arereversed: each one indicates the _lack_ of support for something inthe architecture, rather than the presence. As a consequence, youdon't get the behavior you want if you combine two sets of featurebits.Each SubtargetFeature for an FP architecture version now comes in fourversions, one for each combination of those options. So you can stillsay (for example) '+vfp2' in a feature string and it will mean whatit's always meant, but there's a new string '+vfp2d16sp' meaning theversion without those extra options.A lot of this change is just mechanically replacing positive checksfor the old features with negative checks for the new ones. But onemore interesting change is that I've rearranged getFPUFeatures() sothat the main FPU feature is appended to the output list *before*rather than after the features derived from the Restriction field, sothat -fp64 and -d32 can override defaults added by the main feature.Reviewers: dmgreen, samparker, SjoerdMeijerSubscribers: srhines, javed.absar, eraman, kristof.beyls, hiraditya, zzheng, Petar.Avramovic, cfe-commits, llvm-commitsTags: #clang, #llvmDifferential Revision: https://reviews.llvm.org/D60691llvm-svn: 361845 List of files: /llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp Tue, 28 May 2019 16:13:20 +0000 Simon Tatham <simon.tatham@arm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/lib/Target/ARM/MCTargetDesc/ARMTargetStreamer.cpp#2946cd70 Update the file headers across all of the LLVM projects in the monorepoto reflect the new license.We understand that people may be surprised that we're moving the headerentirely to discuss the new license.

This removes theneed for checks that the provided values map to a proper enum value,allows us to get rid of AK_LAST and prevents comparing values fromdifferent enums. It also removes a bunch of static_castfrom unsigned to enum values and vice versa, at the cost of introducingstatic casts to access AArch64ARCHNames and ARMARCHNames by ArchKind.FPUKind and ArchExtKind are the only remaining old-style enum inTargetParser.h. I think it's beneficial to keep ArchExtKind as old-styleenum, but FPUKind can be converted too, but this patch is quite big, socould do this in a follow-up patch.

However, if the constant pool is explicitly flushed with a .ltorg directive, we should not try to reference constants in the previous pool any longer, since they may be out of range. This fixes assembling hand-written assembler source which repeatedly loads the same constant value, across a binary size larger than the pc-relative fixup range for ldr instructions (4096 bytes). Such assembler source already uses explicit .ltorg instructions to emit constant pools with regular intervals. However if we try to reuse constants emitted in earlier pools, they end up out of range.

This matches the GNU assembler'sbehaviour. We only do this for build attributes which describe thehardware that is expected to be available, not the ones that describeABI compatibility.This is done by moving some of the attribute emission code toARMTargetStreamer, so that it can be shared between the assembly andcode-generation code paths. Since the assembler only creates aMCSubtargetInfo, not an ARMSubtarget, the code had to be changed tocheck raw features, and not use the convenience functions inARMSubtarget.If different attributes are later specified using the .eabi_attributedirective, then they will take precedence, as happens when the same.eabi_attribute is specified twice.This must be enabled by an option, because we don't want to do this whenparsing inline assembly. The attributes would match the ones emitted atthe start of the file, so wouldn't actually change the emitted objectfile, but the extra directives would be added to every inline assemblyblock when emitting assembly, which we'd like to avoid.The majority of the changes in the build-attributes.ll test are justre-ordering the directives, because the hardware attributes are nowemitted before the ABI ones.
