<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-flang-runtime @llvm/pr-subscribers-flang-codegen Author: Michael Kruse (Meinersbur) <details> <summary>Changes</summary> Split some headers into headers for public and private declarations in preparation for #<!-- -->110217. Moving the runtime-private headers in runtime-private include directory will occur in #<!-- -->110298. * Do not use `sizeof(Descriptor)` in the compiler. The size of the descriptor is target-dependent while `sizeof(Descriptor)` is the size of the Descriptor for the host platform which might be too small when cross-compiling to a different platform. Another problem is that the emitted assembly ((cross-)compiling to the same target) is not identical between Flang's running on different systems. Moving the declaration of `class Descriptor` out of the included header will also reduce the amount of #included source. * Do not use `sizeof(ArrayConstructorVector)` and `alignof(ArrayConstructorVector)` in the compiler. Same reason as with `Descriptor`. * Compute the descriptor's extra flags without instantiating a Descriptor. `Fortran::runtime::Descriptor` is defined in the runtime, not the compiler. * Move `InquiryKeywordHashDecode` into runtime-private header. The function is defined in the runtime and trying to call it in the compiler will lead to a link-error. * Move allocator kind magic numbers into common header. They are the only declarations out of `allocator-registry.h` in the compiler as well. --- Patch is 30.29 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/112188.diff 30 Files Affected: -

It is updated by the runtime after each successful allocation or -// reallocation.
