1 @ This test has a partner (ltorg.s) that contains matching 2 @ tests for the .ltorg on linux targets. We need separate files 3 @ because the syntax for switching sections and temporary labels differs 4 @ between darwin and linux. Any tests added here should have a matching 5 @ test added there. 6 7 @RUN: llvm-mc -triple armv7-apple-darwin %s | FileCheck %s 8 @RUN: llvm-mc -triple thumbv5-apple-darwin %s | FileCheck %s 9 @RUN: llvm-mc -triple thumbv7-apple-darwin %s | FileCheck %s 10 11 @ check that ltorg dumps the constant pool at the current location 12 .section __TEXT,a,regular,pure_instructions 13 @ CHECK-LABEL: f2: 14 f2: 15 ldr r0, =0x10002 16 @ CHECK: ldr r0, Ltmp0 17 adds r0, r0, #1 18 adds r0, r0, #1 19 b f3 20 .ltorg 21 @ constant pool 22 @ CHECK: .data_region 23 @ CHECK: .p2align 2 24 @ CHECK-LABEL: Ltmp0: 25 @ CHECK: .long 65538 26 @ CHECK: .end_data_region 27 28 @ CHECK-LABEL: f3: 29 f3: 30 adds r0, r0, #1 31 adds r0, r0, #1 32 33 @ check that ltorg clears the constant pool after dumping it 34 .section __TEXT,b,regular,pure_instructions 35 @ CHECK-LABEL: f4: 36 f4: 37 ldr r0, =0x10003 38 @ CHECK: ldr r0, Ltmp1 39 adds r0, r0, #1 40 adds r0, r0, #1 41 b f5 42 .ltorg 43 @ constant pool 44 @ CHECK: .data_region 45 @ CHECK: .p2align 2 46 @ CHECK-LABEL: Ltmp1: 47 @ CHECK: .long 65539 48 @ CHECK: .end_data_region 49 50 @ CHECK-LABEL: f5: 51 f5: 52 adds r0, r0, #1 53 adds r0, r0, #1 54 ldr r0, =0x10004 55 @ CHECK: ldr r0, Ltmp2 56 adds r0, r0, #1 57 b f6 58 .ltorg 59 @ constant pool 60 @ CHECK: .data_region 61 @ CHECK: .p2align 2 62 @ CHECK-LABEL: Ltmp2: 63 @ CHECK: .long 65540 64 @ CHECK: .end_data_region 65 66 @ CHECK-LABEL: f6: 67 f6: 68 adds r0, r0, #1 69 adds r0, r0, #1 70 71 @ check that ltorg does not issue an error if there is no constant pool 72 .section __TEXT,c,regular,pure_instructions 73 @ CHECK-LABEL: f7: 74 f7: 75 adds r0, r0, #1 76 b f8 77 .ltorg 78 f8: 79 adds r0, r0, #1 80 81 @ check that ltorg works for labels 82 .section __TEXT,d,regular,pure_instructions 83 @ CHECK-LABEL: f9: 84 f9: 85 adds r0, r0, #1 86 adds r0, r0, #1 87 ldr r0, =bar 88 @ CHECK: ldr r0, Ltmp3 89 adds r0, r0, #1 90 adds r0, r0, #1 91 adds r0, r0, #1 92 b f10 93 .ltorg 94 @ constant pool 95 @ CHECK: .data_region 96 @ CHECK: .p2align 2 97 @ CHECK-LABEL: Ltmp3: 98 @ CHECK: .long bar 99 @ CHECK: .end_data_region 100 101 @ CHECK-LABEL: f10: 102 f10: 103 adds r0, r0, #1 104 adds r0, r0, #1 105 106 @ check that use of ltorg does not prevent dumping non-empty constant pools at end of section 107 .section __TEXT,e,regular,pure_instructions 108 @ CHECK-LABEL: f11: 109 f11: 110 adds r0, r0, #1 111 adds r0, r0, #1 112 ldr r0, =0x10005 113 @ CHECK: ldr r0, Ltmp4 114 b f12 115 .ltorg 116 @ constant pool 117 @ CHECK: .data_region 118 @ CHECK: .p2align 2 119 @ CHECK-LABEL: Ltmp4: 120 @ CHECK: .long 65541 121 @ CHECK: .end_data_region 122 123 @ CHECK-LABEL: f12: 124 f12: 125 adds r0, r0, #1 126 ldr r0, =0x10006 127 @ CHECK: ldr r0, Ltmp5 128 129 .section __TEXT,f,regular,pure_instructions 130 @ CHECK-LABEL: f13 131 f13: 132 adds r0, r0, #1 133 adds r0, r0, #1 134 135 @ should not have a constant pool at end of section with empty constant pools 136 @ CHECK-NOT: .section __TEXT,a,regular,pure_instructions 137 @ CHECK-NOT: .section __TEXT,b,regular,pure_instructions 138 @ CHECK-NOT: .section __TEXT,c,regular,pure_instructions 139 @ CHECK-NOT: .section __TEXT,d,regular,pure_instructions 140 141 @ should have a non-empty constant pool at end of this section 142 @ CHECK: .section __TEXT,e,regular,pure_instructions 143 @ constant pool 144 @ CHECK: .data_region 145 @ CHECK: .p2align 2 146 @ CHECK-LABEL: Ltmp5: 147 @ CHECK: .long 65542 148 @ CHECK: .end_data_region 149 150 @ should not have a constant pool at end of section with empty constant pools 151 @ CHECK-NOT: .section __TEXT,f,regular,pure_instructions 152
