Lots of development and debugging tools require a binary to be instrumented with compiler flags. Trick does compiling and linking steps separately and uses several variables to propogate flags to different parts of the build. The following is a convenience function that can be added to your bashrc to easily modify the flags in your environment:
|
||
|
|
|
||
|
|
```
|
||
|
|
add-trickenv () {
|
||
|
|
export CFLAGS="$CFLAGS $1"
|
||
|
|
export CXXFLAGS="$CXXFLAGS $1"
|
||
|
|
export LDFLAGS="$LDFLAGS $1"
|
||
|
|
export TRICK_CFLAGS="$TRICK_CFLAGS $1"
|
||
|
|
export TRICK_CXXFLAGS="$TRICK_CXXFLAGS $1"
|
||
|
|
export TRICK_LDFLAGS="$TRICK_LDFLAGS $1"
|
||
|
|
export TRICK_SYSTEM_CFLAGS="$TRICK_SYSTEM_CFLAGS $1"
|
||
|
|
export TRICK_SYSTEM_CXXFLAGS="$TRICK_SYSTEM_CXXFLAGS $1"
|
||
|
|
export TRICK_SYSTEM_LDFLAGS="$TRICK_SYSTEM_LDFLAGS $1"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
To debug a sim, you will likely need to run a clean build of all of Trick with these flags set.

## Tools that are known to work well with Trick
|
||
|
|
|
||
|
|
GDB/LLDB: `-g`
|
||
|
|
|
||
|
|
gcov: `-fprofile-arcs -ftest-coverage -O0`
|
||
|
|
|
||
|
|
tsan: `-g -fsanitize=thread`
|
||
|
|
|
||
|
|
asan: `-g -fsanitize=address -fsanitize-recover=address`
|
||
|
|
|
||
|
|
Suggest running asan instrumented sims with:
|
||
|
|
|
||
|
|
`ASAN_OPTIONS=halt_on_error=0 ./S_main* <your args>`
