2025-06-09Remove GlobalObject::getAlign/setAlignment (#143188)Eli Friedman
Currently, GlobalObject has an "alignment" property... but it's basically nonsense: alignment doesn't mean the same thing for variables and functions, and it's completely meaningless for ifuncs. This "removes" (actually marking protected) the methods from GlobalObject, adds the relevant methods to Function and GlobalVariable, and adjusts the code appropriately. This should make future alignment-related cleanups easier.
2025-01-20[SystemZ] Add support for new cpu architecture - arch15Ulrich Weigand
This patch adds support for the next-generation arch15 CPU architecture to the SystemZ backend. This includes: - Basic support for the new processor and its features. - Detection of arch15 as host processor. - Assembler/disassembler support for new instructions. - Exploitation of new instructions for code generation. - New vector (signed|unsigned|bool) __int128 data types. - New LLVM intrinsics for certain new instructions. - Support for low-level builtins mapped to new LLVM intrinsics. - New high-level intrinsics in vecintrin.h. - Indicate support by defining __VEC__ == 10305. Note: No currently available Z system supports the arch15 architecture. Once new systems become available, the official system name will be added as supported -march name.

2022-06-30[SystemZ] Add support for tune-cpu attributeKai Nacke
clang (like gcc) has the `-mtune=` command line option. This option adds the `"tune-cpu"` attribute to a function. The intended functionality is that the scheduling model of that cpu is used. E.g. `-mtune=z15 -march=z14` generates only instructions supported on z14 but uses the scheduling model of z15 for it. This PR adds the infrastructure to support this.

2020-08-14[X86][MC][Target] Initial backend support a tune CPU to support -mtuneCraig Topper
This patch implements initial backend support for a -mtune CPU controlled by a "tune-cpu" function attribute. If the attribute is not present X86 will use the resolved CPU from target-cpu attribute or command line. This patch adds MC layer support a tune CPU. Each CPU now has two sets of features stored in their GenSubtargetInfo.inc tables . These features lists are passed separately to the Processor and ProcessorModel classes in tablegen. The tune list defaults to an empty list to avoid changes to non-X86. This annoyingly increases the size of static tables on all target as we now store 24 more bytes per CPU. I haven't quantified the overall impact, but I can if we're concerned. One new test is added to X86 to show a few tuning features with mismatched tune-cpu and target-cpu/target-feature attributes to demonstrate independent control. Another new test is added to demonstrate that the scheduler model follows the tune CPU. I have not added a -mtune to llc/opt or MC layer command line yet. With no attributes we'll just use the -mcpu for both. MC layer tools will always follow the normal CPU for tuning. Differential Revision: https://reviews.llvm.org/D85165
2020-07-23[SystemZ] Ensure -mno-vx disables any use of vector featuresUlrich Weigand
When passing the -vector feature to LLVM (or equivalently the -mno-vx command line argument to clang), the intent is that generated code must not use any vector features (in particular, no vector registers must be used). However, there are some cases where we still could generate such uses; these are all related to some of the additional vector features (like +vector-enhancements-1). Since none of those features are actually usable with -vector, just make sure we disable them all if -vector is given.
2020-06-23Remove GlobalValue::getAlignment().Eli Friedman
This function is deceptive at best: it doesn't return what you'd expect. If you have an arbitrary GlobalValue and you want to determine the alignment of that pointer, Value::getPointerAlignment() returns the correct value. If you want the actual declared alignment of a function or variable, GlobalObject::getAlignment() returns that. This patch switches all the users of GlobalValue::getAlignment to an appropriate alternative. Differential Revision: https://reviews.llvm.org/D80368

This is how it should've been and brings it more in line with std::string_view. There should be no functional change here. This is mostly mechanical from a custom clang-tidy check, with a lot of manual fixups. It uncovers a lot of minor inefficiencies. This doesn't actually modify StringRef yet, I'll do that in a follow-up.

to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license.

Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

2015-05-05[SystemZ] Add z13 vector facility and MC supportUlrich Weigand
This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520
2015-04-01[SystemZ] Support transactional execution on zEC12Ulrich Weigand
The zEC12 provides the transactional-execution facility. This is exposed to users via a set of builtin routines on other compilers. This patch adds LLVM support to enable those builtins. In partciular, the patch: - adds the transactional-execution and processor-assist facilities - adds MC support for all instructions provided by those facilities - adds LLVM intrinsics for those instructions and hooks them up for CodeGen - adds CodeGen support to optimize CC return value checking Since this is first use of target-specific intrinsics on the platform, the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix to return "s390" instead of "systemz", since the naming convention for GCC intrinsics uses "s390" on the platform, and it neemed more straight- forward to use the same convention for LLVM IR intrinsics. An associated clang patch makes the intrinsics (and command line switches) available at the source-language level. For reference, the transactional-execution instructions are documented in the z/Architecture Principles of Operation for the zEC12: http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf The associated builtins are documented in the GCC manual: http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html Index: llvm-head/lib/Target/SystemZ/SystemZOperators.td =================================================================== --- llvm-head.orig/lib/Target/SystemZ/SystemZOperators.td +++ llvm-head/lib/Target/SystemZ/SystemZOperators.td @@ -79,6 +79,9 @@ def SDT_ZI32Intrinsic : SDTypeProf def SDT_ZPrefetch : SDTypeProfile<0, 2, [SDTCisVT<0, i32>, SDTCisPtrTy<1>]>;

2015-03-31[SystemZ] Support RISBGN instruction on zEC12Ulrich Weigand
So far, we do not yet support any instruction specific to zEC12. Most of the facilities added with zEC12 are indeed not very useful to compiler code generation, but there is one exception: the miscellaneous-extensions facility provides the RISBGN instruction, which is a variant of RISBG that does not set the condition code. Add support for this facility, MC support for RISBGN, and CodeGen support for prefering RISBGN over RISBG on zEC12, unless we can actually make use of the condition code set by RISBG. llvm-svn: 233690
2015-03-31[SystemZ] Use POPCNT instruction on z196Ulrich Weigand
We already exploit a number of instructions specific to z196, but not yet POPCNT. Add support for the population-count facility, MC support for the POPCNT instruction, CodeGen support for using POPCNT, and implement the getPopcntSupport TargetTransformInfo hook. llvm-svn: 233689
