|
|
--
|
|
-- This module can be used to debug the JIT compiler itself. It dumps the
|
|
-- code representations and structures used in various compiler stages.
|
|
--
|
|
-- Example usage:
|
|
--
|
|
-- luajit -jdump -e "local x=0; for i=1,1e6 do x=x+i end; print(x)"
|
|
-- luajit -jdump=im -e "for i=1,1000 do for j=1,1000 do end end" | less -R
|
|
-- luajit -jdump=is myapp.lua | less -R
|
|
-- luajit -jdump=-b myapp.lua
|
|
-- luajit -jdump=+aH,myapp.html myapp.lua
|
|
-- luajit -jdump=ixT,myapp.dump myapp.lua
|
|
--
|
|
-- The first argument specifies the dump mode. The second argument gives
|
|
-- the output file name. Default output is to stdout, unless the environment
|
|
-- variable LUAJIT_DUMPFILE is set. The file is overwritten every time the
|
|
-- module is started.
|
|
--
|
|
-- Different features can be turned on or off with the dump mode. If the
|
|
-- mode starts with a '+', the following features are added to the default
|
|
-- set of features; a '-' removes them. Otherwise the features are replaced.
|
|
--
|
|
-- The following dump features are available (* marks the default):
|
|
--
|
|
-- * t Print a line for each started, ended or aborted trace (see also -jv).
|
|
-- * b Dump the traced bytecode.
|
|
-- * i Dump the IR (intermediate representation).
|
|
-- r Augment the IR with register/stack slots.
|
|
-- s Dump the snapshot map.
|
|
-- * m Dump the generated machine code.
|
|
-- x Print each taken trace exit.
|
|
-- X Print each taken trace exit and the contents of all registers.
|
|
-- a Print the IR of aborted traces, too.
|
|
--
|
|
-- The output format can be set with the following characters:
|
|
--
|
|
-- T Plain text output.
|
|
-- A ANSI-colored text output
|
|
-- H Colorized HTML + CSS output.
|
|
--
|
|
-- The default output format is plain text. It's set to ANSI-colored text
|
|
-- if the COLORTERM variable is set. Note: this is independent of any output
|
|
-- redirection, which is actually considered a feature.
|
|
--
|
|
-- You probably want to use less -R to enjoy viewing ANSI-colored text from
|
|
-- a pipe or a file. Add this to your ~/.bashrc: export LESS="-R"
