Previously if the user configured their build but then changed LLVM_ENABLED_PROJECT and reconfigured it had no effect on what projects were actually built. This was very confusing behaviour. The reason for this is that the value of the `LLVM_TOOL_<PROJECT>_BUILD` variables are already set. The problem here is that we have two sources of truth: * The projects listed in LLVM_ENABLE_PROJECTS. * The projects enabled/disabled with LLVM_TOOL_<PROJECT>_BUILD. At configure time we have no real way of knowing which source of truth the user wants so we apply the following heuristic: If the user ever sets `LLVM_ENABLE_PROJECTS` in the CMakeCache then that is used as the single source of truth and we force the `LLVM_TOOL_<PROJECT>_BUILD` CMake cache variables to have the appropriate values that match the contents of the `LLVM_ENABLE_PROJECTS`. If the user never sets `LLVM_ENABLE_PROJECTS` then they can continue to use and set the `LLVM_TOOL_<PROJECT>_BUILD` variables as the "source of truth". The problem with this approach is that if the user ever tries to use both `LLVM_ENABLE_PROJECTS` and `LLVM_TOOL_<PROJECT>_BUILD` for the same build directory then any user set value for `LLVM_TOOL_<PROJECT>_BUILD` variables will get overwriten, likely without the user noticing. Hopefully the above shouldn't matter in practice because the LLVM_TOOL_<PROJECT>_BUILD variables are not documented, but LLVM_ENABLE_PROJECTS is. We should probably deprecate the `LLVM_TOOL_<PROJECT>_BUILD` variables at some point by turning them into to regular CMake variables that don't live in the CMake cache.

# * The case where the user previously had `LLVM_ENABLE_PROJECTS` set to a
# non-empty list but now the user wishes to disable building all other projects
# by setting `LLVM_ENABLE_PROJECTS` to an empty string. In that case we still

Add PerfJITEventListener for perf profiling support. This new JIT event listener supports generating profiling data for the linux 'perf' profiling tool, allowing it to generate function and instruction level profiles. Currently this functionality is not enabled by default, but must be enabled with LLVM_USE_PERF=yes. Given that the listener has no dependencies, it might be sensible to enable by default once the initial issues have been shaken out. I followed existing precedent in registering the listener by default in lli. Should there be a decision to enable this by default on linux, that should probably be changed. Please note that until https://reviews.llvm.org/D47343 is resolved, using this functionality with mcjit rather than orcjit will not reliably work. Disregarding the previous comment, here's an example: $ cat /tmp/expensive_loop.c bool stupid_isprime(uint64_t num) { if (num == 2) return true; if (num < 1 || num % 2 == 0) return false; for(uint64_t i = 3; i < num / 2; i+= 2) { if (num % i == 0) return false; } return true; } int main(int argc, char **argv) { int numprimes = 0; for (uint64_t num = argc; num < 100000; num++) { if (stupid_isprime(num)) numprimes++; } return numprimes; } $ clang -ggdb -S -c -emit-llvm /tmp/expensive_loop.c -o /tmp/expensive_loop.ll $ perf record -o perf.data -g -k 1 ./bin/lli -jit-kind=mcjit /tmp/expensive_loop.ll 1 $ perf inject --jit -i perf.data -o perf.jit.data $ perf report -i perf.jit.data - 92.59% lli jitted-5881-2.so [.] stupid_isprime stupid_isprime main llvm::MCJIT::runFunction llvm::ExecutionEngine::runFunctionAsMain main __libc_start_main 0x4bf6258d4c544155 + 0.85% lli ld-2.27.so [.] do_lookup_x And line-level annotations also work: │ for(uint64_t i = 3; i < num / 2; i+= 2) { │1 30: movq $0x3,-0x18(%rbp) 0.03 │1 38: mov -0x18(%rbp),%rax 0.03 │ mov -0x10(%rbp),%rcx │ shr $0x1,%rcx 3.63 │ ┌──cmp %rcx,%rax │ ├──jae 6f │ │ if (num % i == 0) 0.03 │ │ mov -0x10(%rbp),%rax │ │ xor %edx,%edx 89.00 │ │ divq -0x18(%rbp) │ │ cmp $0x0,%rdx 0.22 │ │↓ jne 5f │ │ return false; │ │ movb $0x0,-0x1(%rbp) │ │↓ jmp 73 │ │ } 3.22 │1 5f:│↓ jmp 61 │ │ for(uint64_t i = 3; i < num / 2; i+= 2) { Subscribers: mgorny, llvm-commits Differential Revision: https://reviews.llvm.org/D44892 llvm-svn: 337789

[RFC] Build LLVM-C.dll on MSVC that exports only the C API Summary: Hello! This commit adds a LLVM-C target that is always built on MSVC. A big fat warning, this is my first cmake code ever so there is a fair bit of I-have-no-idea-what-I'm-doing going on here. Which is also why I placed it outside of llvm-shlib as I was afraid of breaking things of other people. Secondly llvm-shlib builds a LLVM.so which exports all symbols and then does a thin library that points to it, but on Windows we do not build a LLVM.dll so that would have complicated the code more. The patch includes a python script that calls dumpbin.exe to get all of the symbols from the built libraries. It then grabs all the symbols starting with LLVM and generates the export file from those. The export file is then used to create the library just like the LLVM-C that is built on darwin. Improvements that I need help with, to follow up this review. - Get cmake to make sure that dumpbin.exe is on the path and wire the full path to the script. - Use LLVM-C.dll when building llvm-c-test so we can verify that the symbols are exported. - Bundle the LLVM-C.dll with the windows installer. Why do this? I'm building a language frontend which is self-hosting, and on windows because of various tooling issues we have a problem of consuming the LLVM*.lib directly on windows. Me and the users of my projects using LLVM would be greatly helped by having LLVM-C.dll built and shipped by the Windows installer. Not only does LLVM takes forever to build, you have to run a extra python script in order to get the final DLL. Any comments, thoughts or help is greatly appreciated. Cheers, Jakob.

Add PerfJITEventListener for perf profiling support. This new JIT event listener supports generating profiling data for the linux 'perf' profiling tool, allowing it to generate function and instruction level profiles. Currently this functionality is not enabled by default, but must be enabled with LLVM_USE_PERF=yes. Given that the listener has no dependencies, it might be sensible to enable by default once the initial issues have been shaken out. I followed existing precedent in registering the listener by default in lli. Should there be a decision to enable this by default on linux, that should probably be changed. Please note that until https://reviews.llvm.org/D47343 is resolved, using this functionality with mcjit rather than orcjit will not reliably work.
