* Fix CID 508418 - Uninitialized struct * Fix CID 509089 - Fix OOB read and write * Fix CID 509088 - OOB. Also adds tests and to ensure no OOB access. * Fix CID 509085 - Resource leak. * Fix CID 508414 and companions - Using undefined values. * Fix CID 508405 - Use of uninitialized value * Remove unnecessary and badly implemented dev fuzz code. * Fix CID 508396 - Uninitialzied variable. * Fix CID 508393, 508365 -- OOB read. * Fix CID 432207 - OVerlapping memory access. * Remove unused functions * Fix CID 432170 - Overlapping memory access. * Fix CID 166022 - Check for negative index * Let strncat not depend n src operand. * Fix 509083 and 509084 - NULL dereference * Remove duplicated code. * Initialize sysop * Fix resource leak * Remove unreachable code. * Remove duplicate code. * Add assert to check return value of cmoack * Fixed: d should be a signed value, since it is checked against < 0 * Add missing break. * Add NULL check * Fix signs of binary search comparisons. * Add explicit cast of or result * Fix correct scope of case. * Handle invalid integer type. * Return UINT_MAX instead of implicitly casted -1 * Remove dead code * Fix type of im * Fix type of d * Remove duplicated code. * Add returns after CS_ASSERTS * Check for len == 0 case. * Ensure shift operates on uint64 * Replace strcpy with strncpy. * Handle edge cases for 32bit rotate * Fix some out of enum warnings * Replace a strcpy with strncpy. * Fix increment of address * Skip some linting * Fix: set instruction id * Remove unused enum * Replace the last usages of strcpy with SStream functions. * Increase number of allowed AArch64 operands. * Check safety of incrementing t the next operand. * Fix naming of operand * Update python constants * Fix option setup of CS_OPT_DETAIL_REAL * Document DETAIL_REAL has to be used with CS_OPT_ON. * Run Coverity scan every Monday. * Remove dead code * Fix OOB read * Rename macro to reflect it is only used with sstreams * Fix rebase issues
