ssadump(1) a tool for displaying and interpreting the SSA form of Go programs


ssadump [flags] args ...


SSA builder and interpreter.

When -run is specified, ssadump will find the first package that defines a main function and run it in the interpreter. If none is found, the tests of each package will be run instead.


Options controlling the SSA builder. The value is a sequence of zero or more of these letters:

C       perform sanity [C]hecking of the SSA form.
D       include [D]ebug info for every function.
P       log [P]ackage inventory.
F       log [F]unction SSA code.
S       log [S]ource locations as SSA builder progresses.
G       use binary object files from gc to provide imports (no code).
L       build distinct packages seria[L]ly instead of in parallel.
N       build [N]aive SSA form: don't replace local loads/stores with registers.

write cpu profile to file

Options controlling the SSA test interpreter. The value is a sequence of zero or more more of these letters:
R       disable [R]ecover() from panic; show interpreter crash instead.
T       [T]race execution of the program.  Best for single-threaded programs!

Invokes the SSA interpreter on the program.


Quickly dump SSA form of a single package:

      ssadump -build=FPG hello.go

Interpret a program, with tracing:

      ssadump -run -interp=T hello.go

Interpret the unicode package's tests, verbosely:

      ssadump -run unicode -- -test.v
