Sunflower Full-System Hardware Emulator and Physical System Simulator for Sensor-Driven Systems. Built-in architecture modeling of Hitachi SH (j-core), RISC-V, and more.
Add support for 64-bit native execution.
`lex-hitachi-sh.c` and `lex-riscv.c` differ only in the tokens for their assembly instructions, so the rest (tokens for Sunflower commands and the lexical analyser function) is all duplicated.
`SF_BITFLIP_ANALYSIS` only supported on SuperH. This issue is related to #176, since the bit flip analysis is currently tied to a number of superH structures, including the `S->N` numa structure.
Use C99 platform-independent formatting specifiers throughout (e.g., `%zu` for `size_t` and `%"PRIu32"` for `uint32_t`), replacing the current mix of `%d` and `UH8LONGFMT` etc.
Wrong size in `snprintf` in `uncertain_upe.c`: ``` uncertain_upe.c:589:49: warning: ‘%-*d’ directive output truncated writing between 5 and 11 bytes into a region of size 4 [-Wformat-truncation=] result = snprintf(buffer, PRINT_DIGITS...
The constants in the enum should be named based on the coding conventions (e.g., `kSunflowerInstructionLatencyIndexIF`) to make their use left confusing, since the pipeline structure (`P`) also has fields called...

Missing function prototypes and wrong return types in `memory-hierarchy-riscv.c` ``` memory-hierarchy-riscv.c:204:3: warning: implicit declaration of function ‘write_2’; did you mean ‘mwrite’?
