Jakub,
this patch augments the lto wrapper to print out the arguments to spawned
commands when verbose. I found this useful in debugging recent development.
ok for trunk?
Err - fork_execute through collect_execute already does this if
verbose || debug.
So better figure out why this doesn't work.
All I can add is that it really doesn't work, so far to get at the arguments
passed to the offloading cc1/cc1plus/f951, I had to strace -s 1024 -v and
capture what has been passed to the compiler and the content of the
temporary file with options.
Is this because collect_execute prints the variant with the response file?
Then better fix that. Of course we only print the driver invocation - but
that's the same with the proposed patch.
It did surprise me that the usual machinery wasn't printing this stuff, but I
didn't investigate why.
