The flag -frtl-abstract-sequences was removed and the relevant testcases
deleted. Should we resolve this PR as WONTFIX ?

Any progress on this patch? IMHO an option that doesn't work on most of the
primary and secondary arches deserves to be disabled.

(In reply to comment #10)
It fails on arm-eabi with -mthumb and/or -fPIC.
Currently -fPIC is not well tested.
I have created a separate PR36240 to track all PIC issues.

The failure was introduced between r132949 and r132965. The two mainline
patches during that time were Richi's alias change and Kenny's dataflow change.
Given the RTL failure, it more likely is caused by the dataflow

Sorry, the range is r132891 to r132965. So this is likely due to Loko's patch.

-frtl-abstract-sequences
It is a size optimization method. This option is to find identical
sequences of code, which can be turned into pseudo-procedures and then replace
all occurrences with calls to the newly
