* CMake: Make most target symbols hidden by defaultTom Stellard2020-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: For builds with LLVM_BUILD_LLVM_DYLIB=ON and BUILD_SHARED_LIBS=OFF this change makes all symbols in the target specific libraries hidden by default. A new macro called LLVM_EXTERNAL_VISIBILITY has been added to mark symbols in these libraries public, which is mainly needed for the definitions of the LLVMInitialize* functions. This patch reduces the number of public symbols in libLLVM.so by about 25%. This should improve load times for the dynamic library and also make abi checker tools, like abidiff require less memory when analyzing libLLVM.so One side-effect of this change is that for builds with LLVM_BUILD_LLVM_DYLIB=ON and LLVM_LINK_LLVM_DYLIB=ON some unittests that access symbols that are no longer public will need to be statically linked.

* ARM: Don't emit R_ARM_NONE relocations to compact unwinding decoders in ↵Peter Collingbourne2019-11-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | .ARM.exidx on Android. These relocations are specified by the ARM EHABI (section 6.3). As I understand it, their purpose is to accommodate unwinder implementations that wish to reduce code size by placing the implementations of the compact unwinding decoders in a separate translation unit, and using extern weak symbols to refer to them from the main unwinder implementation, so that they are only linked when something in the binary needs them in order to unwind. However, neither of the unwinders used on Android (libgcc, LLVM libunwind) use this technique, and in fact emitting these relocations ends up being counterproductive to code size because they cause a copy of the unwinder to be statically linked into most binaries, regardless of whether it is actually needed. Furthermore, these relocations create circular dependencies (between libc and the unwinder) in cases where the unwinder is dynamically linked and libc contains compact unwind info. Therefore, deviate from the EHABI here and stop emitting these relocations on Android. Differential Revision: https://reviews.llvm.org/D70027

* [ARM] Add the non-MVE instructions in Arm v8.1-M.Simon Tatham2019-06-111-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the new family of conditional selection / increment / negation instructions; the low-overhead branch instructions (e.g. BF, WLS, DLS); the CLRM instruction to zero a whole list of registers at once; the new VMRS/VMSR and VLDR/VSTR instructions to get data in and out of 8.1-M system registers, particularly including the new VPR register used by MVE vector predication. To support this, we also add a register name 'zr' (used by the CSEL family to force one of the inputs to the constant 0), and operand types for lists of registers that are also allowed to include APSR or VPR (used by CLRM). The VLDR/VSTR instructions also need a new addressing mode. The low-overhead branch instructions exist in their own separate architecture extension, which we treat as enabled by default, but you can say -mattr=-lob or equivalent to turn it off.

| | | | | | | | | | | | | | | This reverts r362990 (git commit 374571301dc8e9bc9fdd1d70f86015de198673bd) This was causing linker warnings on Darwin: ld: warning: direct access in function 'llvm::initializeEvexToVexInstPassPass(llvm::PassRegistry&)' from file '../../lib/libLLVMX86CodeGen.a(X86EvexToVex.cpp.o)' to global weak symbol 'void std::__1::__call_once_proxy<std::__1::tuple<void* (&)(llvm::PassRegistry&), std::__1::reference_wrapper<llvm::PassRegistry>&&> >(void*)' from file '../../lib/libLLVMCore.a(Verifier.cpp.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings. llvm-svn: 363028

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.

* Fix ARMv4 supportJoerg Sonnenberger2017-08-281-2/+2
| | | | | | | | | | | | | | | | | | ARMv4 doesn't support the "BX" instruction, which has been introduced with ARMv4t. Adjust the call lowering and tail call implementation accordingly. Further changes are necessary to ensure that presence of the v4t feature is correctly set. Most importantly, the "generic" CPU for thumb-* triples should include ARMv4t, since thumb mode without thumb support would naturally be pointless. Add a couple of asserts to ensure thumb instructions are not emitted without CPU support. Differential Revision: https://reviews.llvm.org/D37030 llvm-svn: 311921

* [TargetParser] Use enum classes for various ARM kind enums.Florian Hahn2017-07-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Using c++11 enum classes ensures that only valid enum values are used for ArchKind, ProfileKind, VersionKind and ISAKind. This removes the need for checks that the provided values map to a proper enum value, allows us to get rid of AK_LAST and prevents comparing values from different enums. It also removes a bunch of static_cast from unsigned to enum values and vice versa, at the cost of introducing static casts to access AArch64ARCHNames and ARMARCHNames by ArchKind. FPUKind and ArchExtKind are the only remaining old-style enum in TargetParser.h. I think it's beneficial to keep ArchExtKind as old-style enum, but FPUKind can be converted too, but this patch is quite big, so could do this in a follow-up patch. I could also split this patch up a bit, if people would prefer that.

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

| | | | | | | | | | | | | | | | | Different MCInstrAnalysis classes for arm and thumb mode, each with their own evaluateBranch implementation. I added a test case and fixed the coff-relocations test to use '<label>:' rather than '<label>' in the CHECK-LABEL entries, since the ones without the colon would match branch targets. Might be worth noticing that llvm-objdump does not lookup the relocation and thus assigns it a target depending on the encoded immediate which #0, so it thinks it branches to the next instruction.

| | | | | | | | | | | | Previously, subtarget features were a bitfield with the underlying type being uint64_t. Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset. No functional change. The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures. Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables. This should now be fixed. llvm-svn: 238192
* [ARM] Fix typo in subtarget feature list for 7em tripleJohn Brawn2015-05-221-1/+1
| | | | | | | | | | | The list of subtarget features for the 7em triple contains 't2xtpk', which actually disables that subtarget feature. Correct that to '+t2xtpk' and test that the instructions enabled by that feature do actually work. Differential Revision: http://reviews.llvm.org/D9936 llvm-svn: 238022
