Returns a 2-tuple of (variable definition map, variable deletion map) which indicates variables defined and deleted in each block. The algorithm avoids relying on explicit knowledge on loops and distinguish between variables that are defined locally vs variables that come from incoming blocks. We start with simple usage (variable reference) and definition (variable creation) maps on each block. Propagate the liveness info to predecessor blocks until it stabilize, at which point we know which variables must exist before entering each block. Then, we compute the end of variable lives and insert del statements accordingly. Variables are deleted after the last use. Variable referenced by terminators (e.g. conditional branch and return) are deleted by the successors or the caller. rPN)rKrR_patch_var_delsrCinternalescaping)rrNr[s rrZPostProcessor._insert_var_delssB"ll,, S\\22CLL4I4I.>  @rc zURRR5GHupEXR5n/n[ UR SS5H|n[ SUR555n X-n [R5H'up[X5(dMU "X5n X-n Xm-nM) URX45 Xj-nM~ /nURn/n[ U5HunnU(aUR SRnO URn[U[R5(dURU5 [USS9HCn[R"UUS9nU(aURU5 M2URU5 ME M U(aURU5 URUR S5 XlX$n[U5H>nUR![R"UUR SRS95 M@ GM g)z Insert delete in each block Nc38# UHoRv M g7fr )rs).0vs r 0PostProcessor._patch_var_dels..s@/?!vv/?sT)reverse)locr)rKr1rUcopyreversedrcrn list_varsir_extension_insert_delsr appendrrrtrvextendprepend)rinternal_dead_mapescaping_dead_maprNr]r^internal_dead_set delete_ptsrzlive_setdead_setTdef_func done_delsrclastloc del_store delete_setvar_namedelnodeescape_dead_sets rr~PostProcessor._patch_var_delss !% 3 3 9 9 ; F 1 9 > > @ J s!34@t~~/?@@#7#;#A#A#CKA!$**$,T$<  -)6) $D !!4"23!-!5DllGI$,Z$8 j$&mmB/33G"hhG!$//KK%!'z4 @H ffX7;G'!((1 G, !A%9&  I& KK b) * M07O"?3  hmmA6F6J6J!KL4a!rsH%99## *F *?v?:p2Fp2r
