Hello,
Would you please tell me how the intermediate variable names and loop
labels are assigned in GIMPLE SSA representation.
for example, consider the following
i.12_43 = i_4;
j.13_44 = j_6;
i.12_45 = i_4;
j.13_46 = j_6;
D.1888_47 = C[i.12_45][j.13_46];
i.12_48 = i_4;
k.14_49 = k_7;
D.1890_50 = A[i.12_48][k.14_49];
k.14_51 = k_7;
j.13_52 = j_6;
D.1891_53 = B[k.14_51][j.13_52];
D.1892_54 = D.1890_50 * D.1891_53;
D.1893_55 = D.1888_47 + D.1892_54;
C[i.12_48][j.13_52] = D.1893_55;
k_57 = k_7 + 1;
now I want to know how exactly the numbers associated with each variable
are obtained.
If you can suggest me a good reference it would be very helpful.
Thank you,
Adarsha Rao.
