Wed, 18 Jun 2025 10:06:25 +0000

src.conf: Add WITH_LLVM_LINK_STATIC_LIBRARIES build knobIn commit 2e47f35be5dc libllvm, libclang and liblldb were converted intoprivate shared libraries. This allowed clang, lld, lldb, and other llvmtools to be linked against these shared libraries, which makes themsmaller and avoids duplication.However, this also comes at the cost of some performance, since thedynamic libraries are quite large, and contain lots of long symbols(mangled C++ identifiers).Add a WITH_LLVM_LINK_STATIC_LIBRARIES build knob that can be used to goback to the previous behavior: libllvm, libclang and liblldb are builtas internal static libraries, i.e. only available during buildworld, andfully linked into the various executables such as clang, lld, etc.PR: 287447Reviewed by: emasteMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D50956 List of files: /src/usr.bin/clang/lld/Makefile

2e47f35be5dc61945afdbd1a70e8fd505c032c94 - Convert libllvm, libclang and liblldb into private shared libraries

Fri, 25 Apr 2025 17:56:39 +0000

Convert libllvm, libclang and liblldb into private shared librariesThis allows clang, lld, lldb, and other llvm tools to be linked againstthese shared libraries, which makes them smaller and avoids duplication.Since these are not quite the same as the shared libraries shipped bythe upstream llvm build system, and we do not want to expose the ABI toexternal programs such as ports, make them private libraries.Note that during the cross-tools stage they are still built as staticlibraries, so the cross compiler and linker are static binaries, as theyhave always been.This also requires a depend-cleanup.sh kludge which will be added in afollow-up commit, to ensure binaries are rebuilt against the sharedlibraries in case of incremental builds.MFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D49967 List of files: /src/usr.bin/clang/lld/Makefile

Revert "Ensure .inc files are regenerated when llvm/clang tblgen binaries change"This reverts commit ab80f0b21fbb9c44d40e6f7a99090188f4ed2f71. The intentof this change was to avoid possible compilation errors when certain.inc files were not regenerated, but the method turns out to cause waymore rebuilds than anticipated. Another method will have to be found,and in the mean time, WITH_CLEAN is the solution that always works.Fixes: ab80f0b21fbb List of files: /src/usr.bin/clang/lld/Makefile

Rework {clang,lldb,llvm}-tblgen invocations to add --write-if-changedThis flag ensures that the tblgen tools do not actually touch theproduced .inc file, if there are no changes to the contents. In turn,this may prevent a number of rebuilds of files that include such .incfiles, saving build time.While here, ensure that the shell invocations to locate the used tblgenbinary do not show unnecessary error messages.Reported by: desMFC after: 1 week List of files: /src/usr.bin/clang/lld/Makefile

ab80f0b21fbb9c44d40e6f7a99090188f4ed2f71 - Ensure .inc files are regenerated when llvm/clang tblgen binaries change

Sat, 25 Feb 2023 15:25:57 +0000

Ensure .inc files are regenerated when llvm/clang tblgen binaries changeWhen doing a fully incremental build (with WITHOUT_CLEAN enabled), froma commit before llvm 15 was merged (3264f6b88fce), to a commit afterthat, a number of .inc files were not regenerated. This could lead tounexpected compilation errors when these .inc files were included fromllvm-project sources, similar to: In file included from /usr/src/contrib/llvm-project/clang/lib/CodeGen/CGBuiltin.cpp:8268: /usr/obj/usr/src/amd64.amd64/lib/clang/libclang/clang/Basic/arm_mve_builtin_cg.inc:279:18: error: no matching constructor for initialization of 'clang::CodeGen::Address' Address Val2 = Address(Val1, CharUnits::fromQuantity(2)); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Work around this by making the .inc files dependent on the tblgen binaryused for generating them. E.g., we can relatively safely assume that ifthe binary gets updated, the .inc files must also be updated. (Althoughthis is not 100% optimal, the gain by complicating things even more isprobaby not worth the effort.)MFC after: 3 daysReviewed by: emasteDifferential Revision: https://reviews.freebsd.org/D38770 List of files: /src/usr.bin/clang/lld/Makefile
