## Ensure that per-page compact encodings (indexes 127 and greater) ## appear in the output of llvm-objdump --unwind-info ## Verify that the common encodings table is full at 0x7f (127) entries. ## ## TODO(gkm): The input is a binary object file constructed from a ## large generated assembler file. For sake of expediency and ## test-time performance, I am following the unfortunate precedent ## that MachO test inputs are binary. ## ## Non-MachO tests largely use YAML inputs. As I understand it, the ## rationale is that these MachO tests were written prior to ## availability of sufficiently-expressive YAML processors. ## ## I consider YAML a submoptimal input format. Better would be ## assembler language inputs convertable to binary via llvm-mc. In ## the case of this test however, the input is very large and the ## overhead of llvm-mc is terrible (~10s) on a debug build. Overhead ## for a release build of llvm-mc is acceptable at ~1s. It would be ## good if there were a way to prefer an installed version of llvm-mc ## to process tests in debug build trees when not testing llvm-mc ## itself. # RUN: llvm-objdump --unwind-info %p/Inputs/unwind-info-excess.macho-x86_64 2>/dev/null | FileCheck %s # CHECK:Contents of __unwind_info section: # CHECK-NEXT: Version: 0x1 # CHECK-NEXT: Common encodings array section offset: 0x1c # CHECK-NEXT: Number of common encodings in array: 0x7f # CHECK: Second level indices: # CHECK: Second level index[0]: offset in section # CHECK: Page encodings: (count = 17) # CHECK: encoding[127]: 0x01010003 # CHECK: encoding[128]: 0x01010002 # CHECK: encoding[129]: 0x01010001 # CHECK: encoding[130]: 0x0102001d # CHECK: encoding[131]: 0x01020015 # CHECK: encoding[132]: 0x0102000d # CHECK: encoding[133]: 0x0102001c # CHECK: encoding[134]: 0x01020014 # CHECK: encoding[135]: 0x0102000c # CHECK: encoding[136]: 0x01020013 # CHECK: encoding[137]: 0x0102000b # CHECK: encoding[138]: 0x01020022 # CHECK: encoding[139]: 0x0102001a # CHECK: encoding[140]: 0x0102000a # CHECK: encoding[141]: 0x01020021 # CHECK: encoding[142]: 0x01020019 # CHECK: encoding[143]: 0x01020011 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[127]=0x01010003 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[128]=0x01010002 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[129]=0x01010001 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[130]=0x0102001d # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[131]=0x01020015 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[132]=0x0102000d # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[133]=0x0102001c # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[134]=0x01020014 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[135]=0x0102000c # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[136]=0x01020013 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[137]=0x0102000b # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[138]=0x01020022 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[139]=0x0102001a # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[140]=0x0102000a # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[141]=0x01020021 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[142]=0x01020019 # CHECK: [{{[0-9]+}}]: function offset={{[x0-9a-f]+}}, encoding[143]=0x01020011
