I just updated to fpc trunk 45658
It seems sometime in the last 3 or 4 month a change was made that
leads to "parentfp" being optimized away.
Even with -O- or -O1 (many users do O1 for debugging)
I've turned off optimization of parentfp when -O- in r45661.
Maybe it can be tied to the -Oostackframe optimisation setting.
Some CPU targets - jvm at least - doesn't support cs_opt_stackframe, but the parentfp optimization applies for any CPU
target.
The parentfp optimization need to be tied to some generic optimization.
cs_opt_remove_empty_proc looks good for this.
