* Adjustments to "decomp" language * Fix a comment * Fix accidental clang-formatting * Fix order * Fix order * Remove junk * Fix OFFSET * Adjustments based on new suggestions * Annotate globals * Globals in ISLE * More globals * Merge from parser2 branch * Allow prepending space for exact marker match * To eliminate noise, require the 0x prefix on offset for marker match * fix test from previous * Count tab stops for indented functions to reduce MISSED_END_OF_FUNCTION noise * FUNCTION to SYNTHETIC where needed * Missed marker conversion on SetAtomId * pylint cleanup, remove unused code * Fix unexpected function end, add more unit tests * Be more strict about synthetic name syntax * Revert "Missed marker conversion on SetAtomId" This reverts commitd87d665127. * Revert "FUNCTION to SYNTHETIC where needed" This reverts commit8c815418d2. * Implicit lookup by name for functions * Fix VTABLE SYNTHETIC and other decomp markers * Get vtable class name * Vtable marker should identify struct * No colon for SIZE comment * Update README.md * Update README.md * Update CONTRIBUTING.md * Update README.md * Update README.md * Update CONTRIBUTING.md * Update README.md * Update CONTRIBUTING.md * Fix destructor/annotation * Update README.md * Update README.md * Update README.md * Update README.md * Update README.md --------- Co-authored-by: disinvite <disinvite@users.noreply.github.com>
