For Tricore Fixed — Tasking Vx-toolset

The typical build pipeline is: C/C++ source → Compiler → Assembly (.s) → Assembler → Object (.o) → Linker/Locator → ELF → Hex Key compiler options (ccTC) | Option | Effect | |--------|--------| | -O2 | High optimization (most common for TriCore) | | --tradeoff=4 | Aggressive loop unrolling & instruction scheduling | | --no-inline-stack | Use call/return instructions instead of stack frames | | --dsp | Enable DSP instruction generation for multiply-accumulate | | --cpu=tc39x | Target specific core (e.g., AURIX TC399) | | --iso | Strict C11 compliance |

__interrupt(0) void reset_handler(void) /* ... */ __interrupt(0x20) void service_request_line_20(void) /* ... */ For writing to special function registers (SFRs), use intrinsic functions:

for a release build:

cctc --debug-info myapp.elf # produce DWARF-2/3 task-debug --device=tc399 --interface=DAP myapp.elf TriCore uses trap vector tables (BIV, BTV). The toolset provides a built-in interrupt macro: The typical build pipeline is: C/C++ source →
