The line /***/ below doesn't generate any code, how to fix? using MSP432p401R
//a tree is similar to an inverted 'V' with two branches (left and right) of equal length. //it's assumed lightCount % 4 == 0 //typedef struct tree //{ // char eyeCatcher[4]; "TREE" // uint32_t * pData; points to left branch leaf // uint32_t size; // //} Tree; //return zero if failed malloc Tree * growTree(uint32_t treeSize) { Tree * result = calloc(sizeof(Tree) + treeSize * sizeof(uint32_t), sizeof(uint8_t)); if (NULL != result) { memcpy(result->eyeCatcher, "TREE", 4); result->pData = (uint32_t*)((uint8_t*)result + sizeof(Tree)); /***/ result->size = treeSize; } return result; } disassembly: 73: { 0x000006E4 B510 PUSH {r4,lr} 0x000006E6 4604 MOV r4,r0 74: Tree * result = calloc(sizeof(Tree) + treeSize * sizeof(uint32_t), sizeof(uint8_t)); 0x000006E8 200C MOVS r0,#0x0C 0x000006EA EB000084 ADD r0,r0,r4,LSL #2 0x000006EE 2101 MOVS r1,#0x01 0x000006F0 F7FFFDF2 BL.W calloc (0x000002D8) 75: if (NULL != result) 76: { 0x000006F4 2800 CMP r0,#0x00 0x000006F6 D006 BEQ 0x00000706 77: memcpy(result->eyeCatcher, "TREE", 4); 0x000006F8 A103 ADR r1,{pc}+0x10 ; @0x00000708 0x000006FA 6809 LDR r1,[r1,#0x00] 78: result->pData = (uint32_t*)((uint8_t*)result + sizeof(Tree)); 79: result->size = treeSize; 80: } 81: return result; 0x000006FC 6001 STR r1,[r0,#0x00] 0x000006FE F100010C ADD r1,r0,#0x0C 0x00000702 E9C01401 STRD r1,r4,[r0,#0x04] 82: } Build output: *** Using Compiler 'V5.06 update 3 (build 300)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin' Rebuild target 'timer32_periodic_mode_led_toggle' compiling timer32_periodic_mode_led_toggle.c... assembling ledDriver.s... compiling changeTree.c... assembling startup_msp432p401r_uvision.s... compiling system_msp432p401r.c... linking...
