1## Ensure that per-page compact encodings (indexes 127 and greater) 2## appear in the output of llvm-objdump --unwind-info 3## Verify that the common encodings table is full at 0x7f (127) entries. 4## 5## TODO(gkm): The input is a binary object file constructed from a 6## large generated assembler file. For sake of expediency and 7## test-time performance, I am following the unfortunate precedent 8## that MachO test inputs are binary. 9## 10## Non-MachO tests largely use YAML inputs. As I understand it, the 11## rationale is that these MachO tests were written prior to 12## availability of sufficiently-expressive YAML processors. 13## 14## I consider YAML a submoptimal input format. Better would be 15## assembler language inputs convertable to binary via llvm-mc. In 16## the case of this test however, the input is very large and the 17## overhead of llvm-mc is terrible (~10s) on a debug build. Overhead 18## for a release build of llvm-mc is acceptable at ~1s. It would be 19## good if there were a way to prefer an installed version of llvm-mc 20## to process tests in debug build trees when not testing llvm-mc 21## itself. 22 23# RUN: llvm-objdump --unwind-info %p/Inputs/unwind-info-excess.macho-x86_64 2>/dev/null | FileCheck %s 24 25# CHECK:Contents of __unwind_info section: 26# CHECK-NEXT: Version: 0x1 27# CHECK-NEXT: Common encodings array section offset: 0x1c 28# CHECK-NEXT: Number of common encodings in array: 0x7f 29 30# CHECK: Second level indices: 31# CHECK: Second level index[0]: offset in section 32# CHECK: Page encodings: (count = 17) 33# CHECK: encoding[127]: 0x01010003 34# CHECK: encoding[128]: 0x01010002 35# CHECK: encoding[129]: 0x01010001 36# CHECK: encoding[130]: 0x0102001d 37# CHECK: encoding[131]: 0x01020015 38# CHECK: encoding[132]: 0x0102000d 39# CHECK: encoding[133]: 0x0102001c 40# CHECK: encoding[134]: 0x01020014 41# CHECK: encoding[135]: 0x0102000c 42# CHECK: encoding[136]: 0x01020013 43# CHECK: encoding[137]: 0x0102000b 44# CHECK: encoding[138]: 0x01020022 45# CHECK: encoding[139]: 0x0102001a 46# CHECK: encoding[140]: 0x0102000a 47# CHECK: encoding[141]: 0x01020021 48# CHECK: encoding[142]: 0x01020019 49# CHECK: encoding[143]: 0x01020011 50 51# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[127]=0x01010003 52# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[128]=0x01010002 53# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[129]=0x01010001 54# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[130]=0x0102001d 55# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[131]=0x01020015 56# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[132]=0x0102000d 57# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[133]=0x0102001c 58# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[134]=0x01020014 59# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[135]=0x0102000c 60# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[136]=0x01020013 61# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[137]=0x0102000b 62# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[138]=0x01020022 63# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[139]=0x0102001a 64# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[140]=0x0102000a 65# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[141]=0x01020021 66# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[142]=0x01020019 67# CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[143]=0x01020011 68
