Hi all,
This patch adds an -mverbose-cost-dump option, similar to the one in
aarch64.
It makes the RTX cost dump print the RTX we're costing in the backend,
as well as its cost.
This can be distracting in other cost-related RTL dumps like combine's.
So now we don't dump the backend information by default, but provide the
power-user option -mverbose-cost-dump
to enable the old verbose dumping.
This option is for GCC developers debugging the compiler only, so no
documentation are added.
No, it doesn't work that way. There is a section in invoke.texi "GCC
Developer Options" that is specifically for options that are only
interesting to GCC developers debugging the compiler. Please document
this new option there.
