[PATCH] Make disabled-optimization warning more informative; increase default max-gcse-memory
* gcc/cprop.c (is_too_expensive): Remove.
(gcse.h): Include.
(one_cprop_pass): Call gcse_or_cprop_is_too_expensive, not
is_too_expensive.
* gcc/gcse.h (gcse_or_cprop_is_too_expensive): Declare.
* gcc/gcse.c (is_too_expensive): Rename to ...
(gcse_or_cprop_is_too_expensive): ... this.
Expand warning to add required size of max-gcse-memory.
(one_pre_gcse_pass): Use it.
(one_code_hoisting_pass): Use it.
* gcc/params.def (max-gcse-memory): Increase from 50MB to 128MB.
