xref: /llvm-project/llvm/test/tools/llvm-objdump/MachO/unwind-info-excess-x86_64.test (revision 61a5502a93ab938edc66422e41ad98757a6f920b)
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.
