Hello, I tried to compile a .gcal file using gcalc fe. test.gcal contains only x=2; [root@is010178 Gcalc]# /usr/local/bin/gcal -S -fdump-tree-all t.gcal calc1: note: primary: INTEGER calc1: note: expression: primary calc1: note: expression: expression '=' expression calc1: note: statements: statements stmt when I look at gimple and generic IR I notice that it is not the same structure (as Philip said). I red last year papers in the GCC summit saying that gimple and generic have the same grammar with some restriction in gimple: only 3 adress structure are allowed, ... but I can see here that Generic is a composed of tree codes (function_decl, integer_cst, ...) however gimple is a set of gimple instruction that are different from tree code (gimple_assign, gimple_bind,... ) My questions are: 1. Is this difference due to changes applyed to Gimple that becomes based on tuples rather than trees ? 2. what is the function (in the gcalc fe) that transform generic to gimple ? 3. when I want to generate the executable from x=2 (I omit the -S option) I get this error (linker error) [root@is010178 Gcalc]# /usr/local/bin/gcal -fdump-tree-all t.gcal calc1: note: primary: INTEGER calc1: note: expression: primary calc1: note: expression: expression '=' expression calc1: note: statements: statements stmt /usr/bin/ld: cannot find -lgcalc collect2: ld a retourné 1 code d'état d'exécution thanks Asma
