1. We don’t accept, and have never accepted, patches by e-mail. Please familiarize yourself with this project’s own README.md. For an expanded description of the process, consult the Chromium development and contribution process. It would also behoove you to consider the structure of other changes on this mailing list (noting no patches by e-mail) and the method of review linked on every other commit in the repository, going back years.

2. I’m not interested in reviewing changes to add this new architecture to Breakpad.

+ *
+ * (This is C99 source, please don't corrupt it with C++.)
+ *
+ * This file contains the necessary definitions to read minidump files
+ * produced on LOONGARCH. These files may be read on any platform provided
+ * that the alignments of these structures on the processing system are
+ * identical to the alignments of these structures on the producing system.
+ * For this reason, precise-sized types are used. The structures defined
+ * by this file have been laid out to minimize alignment problems by
+ * ensuring that all members are aligned on their natural boundaries.
+ * In some cases, tail-padding may be significant when different ABIs specify
+ * different tail-padding behaviors. To avoid problems when reading or
+ * writing affected structures, MD_*_SIZE macros are provided where needed,
+ * containing the useful size of the structures without padding.
+ *
+ * Structures that are defined by Microsoft to contain a zero-length array
+ * are instead defined here to contain an array with one element, as
+ * zero-length arrays are forbidden by standard C and C++. In these cases,
+ * *_minsize constants are provided to be used in place of sizeof. For a
+ * cleaner interface to these sizes when using C++, see minidump_size.h.
+ *
+ * These structures are also sufficient to populate minidump files.
+ *
+ * Because precise data type sizes are crucial for this implementation to
+ * function properly and portably, a set of primitive types with known sizes
+ * are used as the basis of each structure defined by this file.
