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.
