NAME¶
ssadump - a tool for displaying and interpreting the SSA form of Go programs
SYNOPSIS¶
ssadump [
flags]
args ...
DESCRIPTION¶
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¶
- -build
- 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.
- -cpuprofile
- write cpu profile to file
- -interp
- 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!
- -run
- Invokes the SSA interpreter on the program.
EXAMPLES¶
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
