Walter Bright <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Walter Bright <[email protected]> --- The code generated for symIso() is wrong: 0000: 55 push RBP 0001: 48 8B EC mov RBP,RSP 0004: 48 83 EC 10 sub RSP,010h 0008: 48 89 7D F8 mov -8[RBP],RDI 000c: 83 7D FC 00 cmp dword ptr -4[RBP],0 0010: 0F 95 C0 setnz AL // !!! 0013: C9 leave 0014: C3 ret It should be setz. Curiously, the same code in D gets it right: 0000: 55 push RBP 0001: 48 8B EC mov RBP,RSP 0004: 48 83 EC 10 sub RSP,010h 0008: 48 89 7D F8 mov -8[RBP],RDI 000c: 83 7D FC 00 cmp dword ptr -4[RBP],0 0010: 0F 94 C0 setz AL // correct 0013: C9 leave 0014: C3 ret --
