Mark, this is a new wrong-code bug.
Could you look at it and set a priority please.

wtf:
- # SFT.1_22 = V_MUST_DEF <SFT.1_19>;
+ # SFT.1_22 = V_MUST_DEF <SFT.1_11>;
work.Ul_i.Xl_ui = D.1298_21;
...
- # SFT.1_10 = PHI <SFT.1_12(0), SFT.1_9(11)>;
That is just wrong. DCE is doing something wrong, very wrong.

Eliminating unnecessary statements:
Deleting : SFT.1_10 = PHI <SFT.1_12(0), SFT.1_9(11)>;
Deleting : work.Ul_i.Xl_ui = 0;
Deleting : work.Ul_i.Xl_ui = 0;
Deleting : work.Ul_f.Xl_uf = D.1302_36;
Deleting : work.Ul_f.Xl_uf = D.1302_44;
No SFT.1_10 = PHI <SFT.1_12(0), SFT.1_9(11)>; is not useless

The -fno-tree-sra is need as otherwise SRA actually does it work and renames
the PHIs correctly.
