These edges must remain for the current assembler code to work. If they are removed, the dfs_postorder gets things in weird orders. However, they shouldn't be there for other purposes, e.g. conversion to SSA form.

Here's a brief recap: For each SET_LINENO instruction after the first one, two bytes are added to lnotab. (In some cases, multiple two-byte entries are added.) The first byte is the distance in bytes between the instruction for the last SET_LINENO and the current SET_LINENO. The second byte is offset in line numbers. If either offset is greater than 255, multiple two-byte entries are added -- see compile.c for the delicate details. cCs:g|_d|_d|_d|_d|_g|_dS(Ni(tcodet codeOffsetRtlastlinetlastoffR(R ((s&/usr/lib/python2.6/compiler/pyassem.pyRs      cGsAx$|D]}|iit|qW|it||_dS(N(RR)tchrRR!(R RnR`((s&/usr/lib/python2.6/compiler/pyassem.pyRscCs|idjo||_||_n|i|i}||i}|djo|ii}x0|djo"|d|d|d8}q_Wx6|djo(|||d|d8}d}qW|djp |djo||||n||_|i|_ndS(Nii(RRRRRR)(R tlinenotaddrtlinetpush((s&/usr/lib/python2.6/compiler/pyassem.pyRs.            cCsdi|iS(NRK(RTR(R ((s&/usr/lib/python2.6/compiler/pyassem.pyRscCsditt|iS(NRK(RTRRRR(R ((s&/usr/lib/python2.6/compiler/pyassem.pyRs(RHRIRRRRRR(((s&/usr/lib/python2.6/compiler/pyassem.pyRs     tStackDepthTrackercBseZddZh$dd6dd6dd6dd6dd 6dd 6dd 6dd 6dd 6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd6dd 6dd!6dd"6dd#6dd$6dd%6d&d'6d&d(6dd)6dd*6Zd8d9gZd-Zd.Zd/Zd0Zd1Z d2Z d3Z d4Z d5Z d6Zd7ZRS(:ic Cs#d}d}x|D]}|d}|o|Gn|ii|d}|dj o||}nxC|iD]8\}} |t| |jo| }||}PqlqlW|djo;t||d} | dj o|| |d}qn||jo |}n|o |G|GHqqW|S(Nii(teffectRRtpatternsR!tgetattr( R R;tdebugRtmaxDepthR3Rtdeltatpatt pat_deltatmeth((s&/usr/lib/python2.6/compiler/pyassem.pyRs2         itPOP_TOPitDUP_TOPit LIST_APPENDsSLICE+1sSLICE+2sSLICE+3s STORE_SLICE+0s STORE_SLICE+1s STORE_SLICE+2is STORE_SLICE+3sDELETE_SLICE+0sDELETE_SLICE+1sDELETE_SLICE+2sDELETE_SLICE+3t STORE_SUBSCRt DELETE_SUBSCRt PRINT_ITEMRRt EXEC_STMTt BUILD_CLASSt STORE_NAMEt STORE_ATTRt DELETE_ATTRt STORE_GLOBALt BUILD_MAPt COMPARE_OPt STORE_FASTt IMPORT_STARt IMPORT_NAMEt IMPORT_FROMt LOAD_ATTRit SETUP_EXCEPTt SETUP_FINALLYtFOR_ITERt WITH_CLEANUPtBINARY_tLOAD_cCs|dS(Ni((R R((s&/usr/lib/python2.6/compiler/pyassem.pytUNPACK_SEQUENCEscCs | dS(Ni((R R((s&/usr/lib/python2.6/compiler/pyassem.pyt BUILD_TUPLEscCs | dS(Ni((R R((s&/usr/lib/python2.6/compiler/pyassem.pyt BUILD_LISTscCs"t|d\}}||d S(Nii(R(R targcRR((s&/usr/lib/python2.6/compiler/pyassem.pyt CALL_FUNCTIONscCs|i|dS(Ni(R(R R((s&/usr/lib/python2.6/compiler/pyassem.pytCALL_FUNCTION_VARscCs|i|dS(Ni(R(R R((s&/usr/lib/python2.6/compiler/pyassem.pytCALL_FUNCTION_KW!scCs|i|dS(Ni(R(R R((s&/usr/lib/python2.6/compiler/pyassem.pytCALL_FUNCTION_VAR_KW#scCs| S(N((R R((s&/usr/lib/python2.6/compiler/pyassem.pyt MAKE_FUNCTION%scCs| S(N((R R((s&/usr/lib/python2.6/compiler/pyassem.pyt MAKE_CLOSURE'scCs(|djodS|djodSdS(Niiii((R R((s&/usr/lib/python2.6/compiler/pyassem.pyt BUILD_SLICE*s  cCs|S(N((R R((s&/usr/lib/python2.6/compiler/pyassem.pytDUP_TOPX/s(R i(R i(RHRIRRRR R R RRRRRRRR(((s&/usr/lib/python2.6/compiler/pyassem.pyRsf             (RRRRtcompilerRtcompiler.constsRRRRRR&RReRfRgRhRiRRzRoRRRR(((s&/usr/lib/python2.6/compiler/pyassem.pyts*   " Y2  Bj
