* First working hack of adding 64-bit. Don't judge :) * Made vector_downward work on 64 bit types * vector_downward uses size_t, added offset64 to reflection * cleaned up adding offset64 in parser * Add C++ testing skeleton for 64-bit * working test for CreateVector64 * working >2 GiB buffers * support for large strings * simplified CreateString<> to just provide the offset type * generalize CreateVector template * update test_64.afb due to upstream format change * Added Vector64 type, which is just an alias for vector ATM * Switch to Offset64 for Vector64 * Update for reflection bfbs output change * Starting to add support for vector64 type in C++ * made a generic CreateVector that can handle different offsets and vector types * Support for 32-vector with 64-addressing * Vector64 basic builder + tests working * basic support for json vector64 support * renamed fields in test_64bit.fbs to better reflect their use * working C++ vector64 builder * Apply --annotate-sparse-vector to 64-bit tests * Enable Vector64 for --annotate-sparse-vectors * Merged from upstream * Add `near_string` field for testing 32-bit offsets alongside * keep track of where the 32-bit and 64-bit regions are for flatbufferbuilder * move template<> outside class body for GCC * update run.sh to build and run tests * basic assertion for adding 64-bit offset at the wrong time * started to separate `FlatBufferBuilder` into two classes, 1 64-bit aware, the other not * add test for nested flatbuffer vector64, fix bug in alignment of big vectors * fixed CreateDirect method by iterating by Offset64 first * internal refactoring of flatbufferbuilder * block not supported languages in the parser from using 64-bit * evolution tests for adding a vector64 field * conformity tests for adding/removing offset64 attributes * ensure test is for a big buffer * add parser error tests for `offset64` and `vector64` attributes * add missing static that GCC only complains about * remove stdint-uintn.h header that gets automatically added * move 64-bit CalculateOffset internal * fixed return size of EndVector * various fixes on windows * add SizeT to vector_downward * minimze range of size changes in vector and builder * reworked how tracking if 64-offsets are added * Add ReturnT to EndVector * small cleanups * remove need for second Array definition * combine IndirectHelpers into one definition * started support for vector of struct * Support for 32/64-vectors of structs + Offset64 * small cleanups * add verification for vector64 * add sized prefix for 64-bit buffers * add fuzzer for 64-bit * add example of adding many vectors using a wrapper table * run the new -bfbs-gen-embed logic on the 64-bit tests * remove run.sh and fix cmakelist issue * fixed bazel rules * fixed some PR comments * add 64-bit tests to cmakelist
