[LLVMdev] [LLVMDev] llc and -debug-only?

[Jeff Kunkel]

Many places in the documentation says the -debug and the
-debug-only=... can be used to debug modules. However, I cannot find
this option in llc (llvm version 2.8rc, DEBUG build).

This doc explicitly uses -debug/-debug-only:
http://llvm.org/docs/ProgrammersManual.html#DEBUG_TYPE

Thanks,
Jeff Kunkel

llc -help-hidden

Ciao,

Thanks Duncan,

I assume the debug-pass option (the only option with "debug"
prepending it) is the correct option.

Thanks,

with latest svn I get:

-debug - Enable debug output
-debug-buffer-size=<uint> - Buffer the last N characters of
debug outputuntil program termination. [default 0 -- immediate print-out]
-debug-only=<debug string> - Enable a specific type of debug output
-debug-pass - Print PassManager debugging information
=None - disable debug output
=Arguments - print pass arguments to pass to 'opt'
=Structure - print pass structure before run()
=Executions - print pass name before it is executed
=Details - print pass details when it is
executed

Note that these will only be enabled in an assert or debug build.
