[Flang-RT] Fix GCC 15.1 Fortran Runtime libstdc++ Undefined Symbols (#157385) Define the _GLIBCXX_THROW_OR_ABORT macro to not use its _EXC argument. _EXC may contain an expression constructing an std::exception object which is non-inline and therefore require a link dependency on the libstdc++ runtime. In -fno-exceptions builds it is typically optimized away when appearing in unreachable code, but is still present when compiling with -O0 when compiling with Clang. --------- Co-authored-by: Michael Kruse <github@meinersbur.de> | 9 个月前 | |
[Flang] LLVM_ENABLE_RUNTIMES=flang-rt (#110217) Extract Flang's runtime library to use the LLVM_ENABLE_RUNTIME mechanism. It will only become active when LLVM_ENABLE_RUNTIMES=flang-rt is used, which also changes the FLANG_INCLUDE_RUNTIME to OFF so the old runtime build rules do not conflict. This also means that unless LLVM_ENABLE_RUNTIMES=flang-rt is passed, nothing changes with the current build process. Motivation: * Consistency with LLVM's other runtime libraries (compiler-rt, libc, libcxx, openmp offload, ...) * Allows compiling the runtime for multiple targets at once using the LLVM_RUNTIME_TARGETS configuration options * Installs the runtime into the compiler's per-target resource directory so it can be automatically found even when cross-compiling Also see RFC discussion at https://discourse.llvm.org/t/rfc-use-llvm-enable-runtimes-for-flangs-runtime/80826 | 1 年前 | |
[flang] Generate quadmath_wrapper.h for Flang Evaluate. (#132817) When building Flang with Clang, we need to do the same quadmath.h wrapping as we do for flang-rt. I extracted the CMake code into FlangCommon.cmake, and cleaned up the arguments passing to execute_process (note that -### was treated as - in the original code, because # starts a comment). I believe the Clang command does not require the input source file, so I removed it as well. | 1 年前 |
