This file is a complement of sparse's man page meant to
document options only useful for development on sparse itself.
## Developer options:
### Select the passes
* '-f\<name-of-the-pass\>[-disable|-enable|=last]'
If '=last' is used, all passes after the specified one are disabled.
By default all passes are enabled.
The passes currently understood are:
* 'mem2reg'
* 'optim'
### Debugging
* '-fdump-ir[=\<pass\>[,\<pass\>...]]'
Dump the IR at each of the given passes.
The passes currently understood are:
* 'linearize'
* 'mem2reg'
* 'final'
* '-v<debug-flag>'
Add or display some debug info. The flag can be one of:
* 'dead': annotate dead pseudos.
* 'entry': dump the IR after all optimization passes.
