[CMake] Split the target side of runtimes build Previously, llvm/runtimes/CMakeLists.txt played two different roles: 1. host side which could used to set up the build of runtimes for different targets in the right order; 2. target side to build the runtimes for the specified target. This change splits llvm/runtimes/CMakeLists.txt and moves the target side to runtimes/CMakeLists laying down the foundation for the "A vision for building the runtimes" proposal.

# TODO: Selecting runtimes should be always performed inside the runtimes

[CMake] Add LLVM runtimes directory Summary: There are a few LLVM projects that produce runtime libraries. Ideally runtime libraries should be built differently than other projects, specifically they should be built using the just-built toolchain. There is support for building compiler-rt in this way from the clang build. Moving this logic into the LLVM build is interesting because it provides a simpler way to extend the just-built toolchain to include LLD and the LLVM object file tools. Once this functionality is better fleshed out and tested we’ll want to encapsulate it in a module that can be used for clang standalone builds, and we’ll want to make it the default way to build compiler-rt. With this patch applied there is no immediate change in the build. Moving compiler-rt out from llvm/projects into llvm/runtimes enables the functionality. This code has a few improvements over the method provided by LLVM_BUILD_EXTERNAL_COMPILER_RT. Specifically the sub-ninja command is always invoked, so changes to compiler-rt source files will get built properly, so this patch can be used for iterative development with just-built tools. This first patch only works with compiler-rt. Support for other runtime projects will be coming in follow-up patches.

[runtimes] Allow LLVM_BUILTIN_TARGETS to include Darwin We have two ways of using the runtimes build setup to build the builtins. You can either have an empty LLVM_BUILTIN_TARGETS (or have it include the "default" target), in which case builtin_default_target is called to set up the default target, or you can have actual triples in LLVM_BUILTIN_TARGETS, in which case builtin_register_target is called for each triple. builtin_default_target lets you build the builtins for Darwin (assuming your default triple is Darwin); builtin_register_target does not. I don't understand the reason for this distinction. The Darwin builtins build is special in that a single CMake configure handles building the builtins for multiple platforms (e.g. macOS, iPhoneSimulator, and iOS) and architectures (e.g. arm64, armv7, and x86_64). Consequently, if you specify multiple Darwin triples in LLVM_BUILTIN_TARGETS, expecting each configure to only build for that particular triple, it won't work. However, if you specify a *single* x86_64-apple-darwin triple in LLVM_BUILTIN_TARGETS, that single configure will build the builtins for all Darwin targets, exactly the same way that the default target would. The only difference between the configuration for the default target and the x86_64-apple-darwin triple is that the latter runs the configuration with `-DCOMPILER_RT_DEFAULT_TARGET_ONLY=ON`, but that makes no difference for Apple targets (none of the CMake codepaths which have different behavior based on that variable are run for Apple targets). I tested this by running two builtins builds on my Mac, one with the default target and one with the x86_64-apple-darwin19.5.0 target (which is the default target triple for my clang). The only relevant CMakeCache.txt difference was the following, and as discussed above, it has no effect on the actual build for Apple targets: ``` -//Default triple for which compiler-rt runtimes will be built. -COMPILER_RT_DEFAULT_TARGET_TRIPLE:STRING=x86_64-apple-darwin19.5.0 +//No help, variable specified on the command line. +COMPILER_RT_DEFAULT_TARGET_ONLY:UNINITIALIZED=ON ``` Furthermore, when I add the `-D` flag to compiler-rt's libtool invocations, the libraries produced by the two builds are *identical*. If anything, I would expect builtin_register_target to complain if you tried specifying a triple for a particular Apple platform triple (e.g. macosx), since that's the scenario in which it won't work as you want. The generic darwin triple should be fine though, as best as I can tell. I'm happy to add the error for specific Apple platform triples, either in this diff or in a follow-up.

[runtimes] Allow LLVM_BUILTIN_TARGETS to include Darwin We have two ways of using the runtimes build setup to build the builtins. You can either have an empty LLVM_BUILTIN_TARGETS (or have it include the "default" target), in which case builtin_default_target is called to set up the default target, or you can have actual triples in LLVM_BUILTIN_TARGETS, in which case builtin_register_target is called for each triple. builtin_default_target lets you build the builtins for Darwin (assuming your default triple is Darwin); builtin_register_target does not. I don't understand the reason for this distinction. The Darwin builtins build is special in that a single CMake configure handles building the builtins for multiple platforms (e.g. macOS, iPhoneSimulator, and iOS) and architectures (e.g. arm64, armv7, and x86_64). Consequently, if you specify multiple Darwin triples in LLVM_BUILTIN_TARGETS, expecting each configure to only build for that particular triple, it won't work. However, if you specify a *single* x86_64-apple-darwin triple in LLVM_BUILTIN_TARGETS, that single configure will build the builtins for all Darwin targets, exactly the same way that the default target would. The only difference between the configuration for the default target and the x86_64-apple-darwin triple is that the latter runs the configuration with `-DCOMPILER_RT_DEFAULT_TARGET_ONLY=ON`, but that makes no difference for Apple targets (none of the CMake codepaths which have different behavior based on that variable are run for Apple targets). I tested this by running two builtins builds on my Mac, one with the default target and one with the x86_64-apple-darwin19.5.0 target (which is the default target triple for my clang).

[CMake] Add LLVM runtimes directory Summary: There are a few LLVM projects that produce runtime libraries. Ideally runtime libraries should be built differently than other projects, specifically they should be built using the just-built toolchain. There is support for building compiler-rt in this way from the clang build. Moving this logic into the LLVM build is interesting because it provides a simpler way to extend the just-built toolchain to include LLD and the LLVM object file tools. Once this functionality is better fleshed out and tested we’ll want to encapsulate it in a module that can be used for clang standalone builds, and we’ll want to make it the default way to build compiler-rt. With this patch applied there is no immediate change in the build. Moving compiler-rt out from llvm/projects into llvm/runtimes enables the functionality. This code has a few improvements over the method provided by LLVM_BUILD_EXTERNAL_COMPILER_RT. Specifically the sub-ninja command is always invoked, so changes to compiler-rt source files will get built properly, so this patch can be used for iterative development with just-built tools. This first patch only works with compiler-rt. Support for other runtime projects will be coming in follow-up patches.

[CMake] Prefer multi-target variables over generic target variables in runtimes build Runtimes variables in a multi-target environment are defined like: RUNTIMES_target_VARIABLE_NAME RUNTIMES_target+multi_VARIABLE_NAME In my case, I have a downstream runtimes cache that does the following: set(RUNTIMES_${target}+except_LIBCXXABI_ENABLE_EXCEPTIONS ON CACHE BOOL "") set(RUNTIMES_${target}_LIBCXX_ENABLE_EXCEPTIONS OFF CACHE BOOL "") I found that I was always getting the 'target' variable value (OFF) in my 'target+except' build, which was unexpected. This behavior was caused by the loop in llvm/runtimes/CMakeLists.txt that runs through all variable names, adding '-DVARIABLE_NAME=' options to the subsequent external project's cmake command. The issue is that the loop does a single pass, such that if the 'target' value appears in the cache after the 'target+except' value, the 'target' value will take precedence. I suggest in my change here that the more specific 'target+except' value should take precedence always, without relying on CMake cache ordering.

[CMake] Support stripping and linking output to .build-id directory When installing runtimes with install-runtimes-stripped, we don't want to just strip them, we also want to preserve the debugging information for potential debugging. To make it possible to later find the stripped debugging information, we want to use the .build-id layout: https://fedoraproject.org/wiki/RolandMcGrath/BuildID#Find_files_by_build_ID That is, for libfoo.so with build ID abcdef1234, the debugging information will be installed into lib/debug/.build-id/ab/cdef1234. llvm-objcopy already has support for stripping files and linking the debugging stripped output into the right location. However, CMake doesn't support customizing strip invocation for the *-stripped targets. So instead, we replace CMAKE_STRIP with a custom script that invokes llvm-objcopy with the right command line flags. Differential Revision: https://reviews.llvm.org/D59127 llvm-svn: 355765

[CMake] Support multi-target runtimes build This changes adds support for building runtimes for multiple different targets using LLVM runtimes directory. The implementation follow the model used already by the builtins build which already supports this option. To specify the runtimes targets to be built, use the LLVM_RUNTIME_TARGETS variable, where the valuae is the list of targets to build runtimes for. To pass a per target variable to the runtimes build, you can set RUNTIMES_<target>_<variable> where <variable> will be passed to the runtimes build for <target>. Each runtime target (except for the default one) will be installed into lib/<target> subdirectory. Build targets will be suffixed with the target name.

[CMake] Make the runtimes directory work with bootstrap builds This patch builds on clang r284648, and allows the runtime directory to make the bootstrap builds depend on the builtin libraries. This patch also make the bootstrap build depend on configuring the other runtimes because the libcxx headers are copied during configuration. I have left a TODO in the code to remove that once I come up with a better solution. llvm-svn: 284650

[CMake] Add LLVM runtimes directory Summary: There are a few LLVM projects that produce runtime libraries. Ideally runtime libraries should be built differently than other projects, specifically they should be built using the just-built toolchain. There is support for building compiler-rt in this way from the clang build. Moving this logic into the LLVM build is interesting because it provides a simpler way to extend the just-built toolchain to include LLD and the LLVM object file tools. Once this functionality is better fleshed out and tested we’ll want to encapsulate it in a module that can be used for clang standalone builds, and we’ll want to make it the default way to build compiler-rt. With this patch applied there is no immediate change in the build. Moving compiler-rt out from llvm/projects into llvm/runtimes enables the functionality. This code has a few improvements over the method provided by LLVM_BUILD_EXTERNAL_COMPILER_RT. Specifically the sub-ninja command is always invoked, so changes to compiler-rt source files will get built properly, so this patch can be used for iterative development with just-built tools. This first patch only works with compiler-rt. Support for other runtime projects will be coming in follow-up patches.
